Automate Database Schema Object Check

Monitoring your database schema changes in MySQL/MariaDB provides a huge help as it saves time analyzing your database growth, table definition changes, data size, index size, or row size. For MySQL/MariaDB, running a query referencing information_schema together with performance_schema gives you collective results for further analysis. The sys schema provides you views that serve as collective metrics that are very useful for tracking database changes or activity. If you have many database servers, it would be tedious to run a query all the time. You also have to digest that result into a more readable and easier to understand. In this blog, we'll create an automation that would be helpful as your utility tool to have for your existing database to be monitored and collect metrics regarding database changes or schema change operations.  Creating Automation for Database Schema Object Check In this exercise, we will monitor the following metrics: No primary key tables Duplicate indexes Generate a graph for total number of rows in our database schemas Generate a graph for total size of our database schemas This exercise will give you a heads up and can be modified to gather more advanced metrics from your MySQL/MariaDB database.   Using Puppet for our IaC and Automation This exercise shall use Puppet to provide automation and generate the expected results based on the metrics we want to monitor. We'll not cover the installation and setup for the Puppet, including server and client, so I expect you to know how to use Puppet. You might want to visit our old blog Automated Deployment of MySQL Galera Cluster to Amazon AWS with Puppet, which covers the setup and installation of Puppet. We'll use the latest version of Puppet in this exercise but since our code consists of basic syntax, it would run for older versions of Puppet. Preferred MySQL Database Server In this exercise, we'll use Percona Server 8.0.22-13 since I prefer Percona Server mostly for testing and some minor deployments either business or personal use. Graphing Tool  There are tons of options to use especially using the Linux environment. In this blog, I'll use the easiest that I found and an opensource tool https://quickchart.io/. Let's Play with Puppet The assumption i have made here is that you have setup master server with registered client which is ready to communicate with the master server to receive automatic deployments. Before we proceed, here's the my server information: Master server: 192.168.40.200 Client/Agent Server: 192.168.40.160 In this blog, our client/agent server is where our database server is running.In a real-world scenario, it doesn't have to be especially for monitoring. As long as it's able to communicate into the target node securely, then that is a perfect setup as well. Setup the Module and the Code Go to the master server and in the path /etc/puppetlabs/code/environments/production/module, let's create the required directories for this exercise: mkdir schema_change_mon/{files,manifests}   Create the files that we need touch schema_change_mon/files/graphing_gen.sh touch schema_change_mon/manifests/init.pp Fill-up the init.pp script with the following content: class schema_change_mon ( $db_provider = "mysql", $db_user = "root", $db_pwd = "R00tP@55", $db_schema = [] ) { $dbs = ['pauldb', 'sbtest'] service { $db_provider : ensure => running, enable => true, hasrestart => true, hasstatus => true } exec { "mysql-without-primary-key" : require => Service['mysql'], command => "/usr/bin/sudo MYSQL_PWD="${db_pwd}" /usr/bin/mysql -u${db_user} -Nse "select concat(tables.table_schema,'.',tables.table_name,', ', tables.engine) from information_schema.tables left join ( select table_schema , table_name from information_schema.statistics group by table_schema , table_name , index_name having sum( case when non_unique = 0 and nullable != 'YES' then 1 else 0 end ) = count(*) ) puks on tables.table_schema = puks.table_schema and tables.table_name = puks.table_name where puks.table_name is null and tables.table_type = 'BASE TABLE' and tables.table_schema not in ('performance_schema', 'information_schema', 'mysql');" >> /opt/schema_change_mon/assets/no-pk.log" } $dbs.each |String $db| { exec { "mysql-duplicate-index-$db" : require => Service['mysql'], command => "/usr/bin/sudo MYSQL_PWD="${db_pwd}" /usr/bin/mysql -u${db_user} -Nse "SELECT concat(t.table_schema,'.', t.table_name, '.', t.index_name, '(', t.idx_cols,')') FROM ( SELECT table_schema, table_name, index_name, Group_concat(column_name) idx_cols FROM ( SELECT table_schema, table_name, index_name, column_name FROM statistics WHERE table_schema='${db}' ORDER BY index_name, seq_in_index) t GROUP BY table_name, index_name) t JOIN ( SELECT table_schema, table_name, index_name, Group_concat(column_name) idx_cols FROM ( SELECT table_schema, table_name, index_name, column_name FROM statistics WHERE table_schema='pauldb' ORDER BY index_name, seq_in_index) t GROUP BY table_name, index_name) u where t.table_schema = u.table_schema AND t.table_name = u.table_name AND t.index_name<>u.index_name AND locate(t.idx_cols,u.idx_cols);" information_schema >> /opt/schema_change_mon/assets/dupe-indexes.log" } } $genscript = "/tmp/graphing_gen.sh" file { "${genscript}" : ensure => present, owner => root, group => root, mode => '0655', source => 'puppet:///modules/schema_change_mon/graphing_gen.sh' } exec { "generate-graph-total-rows" : require => [Service['mysql'],File["${genscript}"]], path => [ '/bin/', '/sbin/' , '/usr/bin/', '/usr/sbin/' ], provider => "shell", logoutput => true, command => "/tmp/graphing_gen.sh total_rows" } exec { "generate-graph-total-len" : require => [Service['mysql'],File["${genscript}"]], path => [ '/bin/', '/sbin/' , '/usr/bin/', '/usr/sbin/' ], provider => "shell", logoutput => true, command => "/tmp/graphing_gen.sh total_len" } }   Fill up the graphing_gen.sh file. This script will run on the target node and generate graphs for the total number of rows in our database and also total size of our database. For this script, let's make it simpler ,and allow only MyISAM or InnoDB type of databases. #!/bin/bash graph_ident="${1:-total_rows}" unset json myisam innodb nmyisam ninnodb; json='' myisam='' innodb='' nmyisam='' ninnodb='' url=''; json=$(MYSQL_PWD="R00tP@55" mysql -uroot -Nse "select json_object('dbschema', concat(table_schema,' - ', engine), 'total_rows', sum(table_rows), 'total_len', sum(data_length+data_length), 'fragment', sum(data_free)) from information_schema.tables where table_schema not in ('performance_schema', 'sys', 'mysql', 'information_schema') and engine in ('myisam','innodb') group by table_schema, engine;" | jq . | sed ':a;N;$!ba;s/n//g' | sed 's|}{|},{|g' | sed 's/^/[/g'| sed 's/$/]/g' | jq '.' ); innodb=""; myisam=""; for r in $(echo $json | jq 'keys | .[]'); do if [[ $(echo $json| jq .[$r].'dbschema') == *"MyISAM"* ]]; then nmyisam=$(echo $nmyisam || echo '')$(echo $json| jq .[$r]."${graph_ident}")','; myisam=$(echo $myisam || echo '')$(echo $json| jq .[$r].'dbschema')','; else ninnodb=$(echo $ninnodb || echo '')$(echo $json| jq .[$r]."${graph_ident}")','; innodb=$(echo $innodb || echo '')$(echo $json| jq .[$r].'dbschema')','; fi; done; myisam=$(echo $myisam|sed 's/,$//g'); nmyisam=$(echo $nmyisam|sed 's/,$//g'); innodb=$(echo $innodb|sed 's/,$//g');ninnodb=$(echo $ninnodb|sed 's/,$//g'); echo $myisam "|" $nmyisam; echo $innodb "|" $ninnodb; url=$(echo "{type:'bar',data:{labels:['MyISAM','InnoDB'],datasets:[{label:[$myisam],data:[$nmyisam]},{label:[$innodb],data:[$ninnodb]}]},options:{title:{display:true,text:'Database Schema Total Rows Graph',fontSize:20,}}}"); curl -L -o /vagrant/schema_change_mon/assets/db-${graph_ident}.png -g https://quickchart.io/chart?c=$(python -c "import urllib,os,sys; print urllib.quote(os.environ['url'])") Lastly, go to the module path directory or /etc/puppetlabs/code/environments/production in my setup. Let's create the file  manifests/schema_change_mon.pp. touch manifests/schema_change_mon.pp Then fill the file manifests/schema_change_mon.pp with the following contents, node 'pupnode16.puppet.local' { # Applies only to mentioned node. If nothing mentioned, applies to all. class { 'schema_change_mon': } }   If you're done, you should have the following tree structure just like mine, root@pupmas:/etc/puppetlabs/code/environments/production/modules# tree schema_change_mon schema_change_mon ├── files │ └── graphing_gen.sh └── manifests └── init.pp What does our module do? Our module which is called schema_change_mon does collect the following, exec { "mysql-without-primary-key" : ... Which executes a mysql command and runs a query to retrieve tables without primary keys. Then, $dbs.each |String $db| { exec { "mysql-duplicate-index-$db" : which does collect duplicate indexes that exist in the database tables. Next, the lines generate graphs based on the metrics collected. These are the following lines, exec { "generate-graph-total-rows" : ... exec { "generate-graph-total-len" : … Once the query successfully runs, it generates the graph, which depends on the API provided by https://quickchart.io/. Here are the following results of the graph: Whereas the file logs simply contain strings with its table names, index names. See the result below, root@pupnode16:~# tail -n+1 /opt/schema_change_mon/assets/*.log ==> /opt/schema_change_mon/assets/dupe-indexes.log <== pauldb.c.my_index(n,i) pauldb.c.my_index2(n,i) pauldb.d.a_b(a,b) pauldb.d.a_b2(a,b) pauldb.d.a_b3(a) pauldb.d.a_b3(a) pauldb.t3.b(b) pauldb.c.my_index(n,i) pauldb.c.my_index2(n,i) pauldb.d.a_b(a,b) pauldb.d.a_b2(a,b) pauldb.d.a_b3(a) pauldb.d.a_b3(a) pauldb.t3.b(b) ==> /opt/schema_change_mon/assets/no-pk.log <== pauldb.b, MyISAM pauldb.c, InnoDB pauldb.t2, InnoDB pauldb.d, InnoDB pauldb.b, MyISAM pauldb.c, InnoDB pauldb.t2, InnoDB pauldb.d, InnoDB Why Not Use ClusterControl? As our exercise showcases the automation and getting the database schema statistics such as changes or operations, ClusterControl provides this as well. There are other features as well aside from this and you don't need to reinvent the wheel. ClusterControl can provide the transaction logs such as deadlocks as shown above, or long running queries as shown below:   ClusterControl also shows the DB growth as shown below,   ClusterControl also gives additional information such as number of rows, disk size, index size, and total size.   The schema analyzer under Performance tab -> Schema Analyzer is very helpful. It provides tables without primary keys, MyISAM tables, and duplicate indexes, It also provides alarms in case there are detected duplicate indexes or tables without primary keys such as below,   You can check out more information about ClusterControl and its other features on our Product's page. Conclusion Providing automation for monitoring your database changes or any schema statistics such as writes, duplicate indexes, operation updates such as DDL changes, and many database activities is very beneficial to the DBAs. It helps to quickly identify the weak links and problematic queries that would give you an overview of a possible cause of bad queries that would lock up your database or stale your database.

@cumaeansibyl​ and I spent ten days in Central Europe in 2019, and one of the places we visited was Lindau. We were staying in Basel and already planning to visit Bregenz, Austria (but that’s another story). The direct path to Bregenz was by a combination of Swiss and Austrian trains via St. Margrethen, along the south bank of the Bodensee (Lake Constance).

The day before, we were at a party and one of the locals told us that we could go via German trains to Lindau, and then take a quick ferry across the lake to Bregenz. The timing was comparable, and because of the Baden Württemberg pass was considerably cheaper. Why take two trains through two countries when you could take two trains and a ferry through three countries?

Thus it was that we found ourselves in Lindau, a charming city in Bavaria, Germany, on the north coast of the Bodensee and the only city on the lake with a lighthouse. There’s regular ferry service to various destinations in Germany, Austria, and Switzerland, plus plenty of trains in all directions.

But most important of all, there was a cheap snack shop at Lindau Hauptbahnhof, and Liz experienced her first doner kebab sitting on a bench at a German train station. As one does.

DevOps, Culture Change and the Brass Ring of Velocity

The globe of technology is except the pale of heart. It can be high-stakes as well as the margin in between wild success and also the other day's news is razor thin at times.

In order to remain one step in advance of the competition in the battle for market share, several technology business have actually begun to essentially shift just how they operate in order to raise the velocity with which they build, test and also launch software. What originally started from the agile motion is now evolving right into a new philosophical means of functioning: DevOps.

DevOps is not a substitute of nimble or lean methods even a supplement to them. It fills in the gaps to assist technology companies break down useful stovepipes, automate as much as possible in the spirit of rate and also quality, and fine-tune functional procedure to enable for speed that was unusual 10 years ago.

The thought of a technology business deploying ten updates to an app in a day was preposterous just a couple of years back. Currently, those who have made the change to a DevOps environment are doing this on a normal basis.

It’s a culture thing.

As a business psychologist that concentrates on workplace society, I locate the topic of DevOps an interesting situation research. Technology business are now testing their enduring ideas and assumptions and also moving deeply held ways of functioning to permit considerably better cooperation and velocity.

As I continuously take into consideration DevOps, at its core, as a society change, I cannot aid yet start to frame my own individual ideas about what DevOps is and also isn't really. Right here's exactly what I've thought of until now:

DevOps is less about just what we do and also a lot more about just how we do it. Modern technology framework and also progressing procedures are important in successfully transforming an organization to DevOps principles. However, at the end of the day, DevOps has to do with how job obtains done, and also exactly how individuals communicate with each various other as well as with modern technology to drive performance.

DevOps is not an off-the-shelf option that could merely be implemented. Sadly, there is no one-size-fits-all technique for just how DevOps ought to be carried out. Again, given that DevOps is basically a social change in the means job gets done, it will certainly take somewhat various forms based upon the organization. That's okay. Chef's CTO, Adam Jacob, does a phenomenal task expressing this nuance in his 2015 write-up in ReadWrite.

The individuals side is vital to the equation. While the majority of the DevOps posts I have actually encountered do make passing mention of individuals side of the DevOps equation, extremely few exceed a brief affirmation that it's essential prior to moving on to the process as well as technology/infrastructure components of the improvement. If we truly wish to alter the method individuals function to drive speed in the tech globe, then we need to take a further appearance at this human side of DevOps, and the ways it could support or derail a sustainable DevOps transformation.

DevOps is not a task, it's everyone's job. A quick work search on Indeed.com included only to the Seattle, WA area located over 500 job openings with the term DevOps in the title. Klint Finley's Wired write-up highlights this fad of tech companies altering job titles to include DevOps. Yet, baseding on Finley, DevOps is not a work. It's a vital way of working with each other to drive performance. If this is real (which I happen to completely concur with), then I will go an action even more to suggest that DevOps isn't really one individual's task, it's everybody's job.

The people part of the version appears to be the component that is the very least defined. I've located several DevOps designs in my research, but none have actually fairly struck residence with me. A lot of make reference of individuals or culture element of a DevOps change, yet they often tend to do so in name just, focusing much more heavily on the facilities components. It's important to realize that even more "stuff" is not the remedy to a successful DevOps shift, or any sort of cultural transition for that issue. I dive deeper right into this idea in one more current article.

A DevOps transition could be likened to any sort of business adjustment in the method job obtains done, whether that be organizations relocating toward a client-focused society, those wanting a culture that stands out at high quality and uniformity, or those that are working toward operating at greater speed. If this is true, after that concentrating on the basic aspects of business society that drive the behaviors one needs to execute on their business technique becomes the coatrack where all the various other systems, process and people adjustments hang.

There is clear evidence to recommend that a DevOps method to technology development could have significant effect on the speed of an IT company. This is sustained in the State of DevOps Record generated by PuppetLabs on an annual basis.

That stated, there is likewise data that recommends that a lot of DevOps improvement efforts cannot supply on assumptions. The existing culture of the IT organization does not enable individuals to act in the methods necessary making the jump to DevOps. Based on this, I send that it's time that we review our approach to sustainable DevOps makeover. We have to begin to create a more extensive technique that considers the different people as well as cultural aspects that assist enhance new methods of working.

The trophy of rate is accessible for these forward believing tech firms. The concern is, could they welcome the business adjustment needed to get hold of it?

「Clojure は商用サービス採用事例が少ない」というのは過去の話です．

Puppet が Ruby から Clojure に移行

DevOps 自動化ツールで有名な Puppet は Ruby 製でしたが， その一部は既に Clojure で書かれていました． で，今回の発表は，「一部だけでなく Puppet master を置き換える Pupper Server をリリースするけど，それは Clojure で書きました」 という発表です．ちょっと驚きました．とはいえ， Puppet Labs で Clojure 用のアプリケーションフレームワーク， TrapperKeeper を作っていたので， ある程度は予想できていたのですが．

これから，「Clojure で書かれた製品は？」と聞かれたら Puppet Server と答えましょう．

赤い Ruby より 3 倍速い緑の Clojure

記事中に Ruby 版 (Apache/Passenger) と Clojure 版 (TrapperKeeper) とのベンチマーク比較が掲載さています．ざっくり言うと， Clojure 版は Ruby 版より 3 倍早くなっているようで， Clojure に移行した成果が早速性能面で出ているようです．

これを見て，「Clojure 速い，Ruby 遅い」と思われるかもしれませんが， 私は，「Clojure の 3 倍遅い程度で済んでいるということは， Ruby って以外と性能悪くないです���ね」と思ってしまいました．

だって，Clojure 速いですから．3 倍程度の差なら別に Ruby のままでも良かったのではと思うのですが，それでも， Clojure を使う理由はきっと別のところにあるのでしょうね．

Clojure で Ruby を使う

「Clojure で Ruby を使う」と書いてしまうと， 個人のブログ記事か Qiita のエントリにありがちな技術ブログ記事タイトルに思えるのですが， Puppet Server では Puppet master との互換性を保つために， Clojure で JRuby のインスタンスを作って，その中で，旧 Puppet mster の Ruby コードを動かしているそうです．このおかげで，Puppet master の Ruby コードを Clojure で書き直すことなく， 既存の資産を活かしつつ Clojure で機能拡張できるという，いいとこどりをしています．

これも，Clojure の Java 親和性の高さと JRuby の完成度の高さのおかげですね． 既存 Ruby プロジェクトを Clojure に移行する際の方式として参考になります．

おわりに

Ruby 製の Puppet master が Clojure に移行して Puppet Server になるそうです． JRuby + Clojure という組み合わせにより，

性能向上 (Clojure + JVM = 3 倍速い)

既存資産の継承 (Clojure + JRuby)

の両取りに成功しました．Clojure の採用事例は，Clojure でのスクラッチ開発より， こういった既存の Ruby プロジェクトからの移行により増えていくのかもしれません．

個人的には Salt いいなあと思っていたのですが，Puppet Server に戻りそうです．

New bike bag - Mission Workshop Sanction

I've been using Chrome messenger bags for about ten years, and I've really liked them.  Mine have been all over the world with me, and at least one of them still looks nearly brand new.  However, my riding these days is basically straight commuting between home and the office, so I rarely need the on-the-bike access that messenger bag gives me.  

Even worse, my left shoulder, which bears the whole bag, has recently decided it hates my guts and would like me to die, or at least share the load across both shoulders.  As much as I like a night on the couch with bourbon, painkillers, and a hot water bottle, I can't afford to get into the habit of that kind of thing.

So, I went to start looking at new bags.  Because I live in PDX, I need something waterproof; because I live in Portland but travel to San Francisco, Palo Alto, NYC, London, and more, I need something that looks good; and because I travel a ton and hate overpacking, I need something small (where my definition of small is I can *barely* fit my daily needs plus an extra shirt/socks/etc for one night away).  All that, plus of course it should be comfortable and last 10 or 20 years.  I've also been trying hard to buy things that don't look quite as plasticky as most, um, everything looks these days, so extra points for natural fibers or something that does a good job of faking it.

I looked at quite a few other bags, but everything seemed to fail really quickly on either 'look good' or 'be small', and many failed on both.  It was obvious right away that I had to give up on buying anything that didn't look plasticky - everything was plastic or nylon, and really obviously so.  One of the other things about most of the bags I found was that they tended to be more like gear and less like everyday bags, and they tended to be very complicated with lots of straps and pockets and things.  This could be done well, but in most cases (heh heh) the bags were either too complicated, with lots of straps and extra pockets, or too simple, with just a big middle pocket and little to no organization.

I decided I had to see a bunch of bags in person, so I set out to some shops in town with my then-day bag full of everything I carry with me every day and a bit of extra clothing to simulate an overnight trip (yes, I pack light).  My first stop was River City Cycles, a fantastic shop for commuters, and that's where I ended up buying my bag.  I was able to try my top contenders there (from Chrome and Timbuk2), but the Chrome bags were, um, gigantic, and the Timbuk2 bags were just to plasticky for me.

The first time I looked at the Mission Workshop Sanction, it looked both huge and plasticky.  However, after trying everything else, I decided to actually load my stuff in one before I left.  Then I noticed that they had two varieties - one made of nylon (linked above) and one made of waxed canvas, which I adore.  It wears kind of like leather, in that it looks better with age, but it's about as waterproof as you can get without plastic bags and has a great feel.

After loading everything into this bag, I realized it was a lot smaller than it looked (it helped that I had tried some truly big bags prior to this).  In fact, it was kind of too small for my torso, given how the straps worked out.  However, I wore it around the shop for awhile, and based on the fact that it was the last one they had in the gray color I liked (along with River City's great return policy), I decided to buy now and try it over the weekend.  In case it's not obvious, I kept the bag after all.

Here, roughly, is how I tested it out.

First, my daily load (with an extra jacket just in case) outside of the bag.  It's mostly laptop, ipad, a cable bag or two, and a bunch of little things:

Then the bag actually loaded up.  This is how I'd use the bag 95% of the time, so it's the most important test:

Here's how the bag looks open, so you can see where it all goes:

And you can see when it stands up that it's really not very full:

I also tried it with a full load of overnight clothing, in an Eagle Creek clothing folder (which I really only use on overnight trips):

You can see that the bag is pretty round with this in it.

I also took a shot that showed two aspects of the bag I wasn't so fond of, and one nice feature:

My cat hair sticks to the bottom, and the bottom part of the straps are too long (I've bound mine with rubber bands).  I do like the loop for attaching a bike light, though.

I was able to fit everything into the bag in all cases, but I barely fit the overnight kit (and in fact, on my first actual overnight trip with the bag, I had to leave some stuff behind, which I consider a feature).  The bag also never got too round or uncomfortable, and after going on a few walks and bike rides, I was comfortable that this was the right bag.

I looked into the bag a bit more (yes, I'm a bit maniacal on my research), and it turns out this waxed canvas version is a special version, so it turns out that one of the best features of this bag is that no one else in my office can have one, because it's all sold out. :)  Yes, the Puppet Labs office is full of bike and gear nuts, with a strong overlap on people who pack really light.  There is another special version of the Sanction, though, that might be worth checking out, and the normal version is still a great bag.

After using the pack for a month, including on an overnight trip, I'm still happy with it.  My only real complaint is that it doesn't have a handle on the side, which I would like for when I can't put it on my bag.  I didn't expect to use the "special" laptop compartment, because it's just a separate pocket behind the main pocket, but it ends up being really convenient - the main pocket can be packed full, but I can still slide my laptop in and out of its pocket.  It also turns out that the little pocket in front perfectly fits my ipad, which is an added bonus.

July 21st-23rd Update? :D

Okay so I've been a bit behind with these updates. It's hard to do so when I don't have my apartment to live in with decent internet :(

Luckily there's not too much to update, mostly been focusing on setting up the PuppetDBQuery module and working out how best to use it in our scenario. That seems to be done and working now. One thing I did notice, which I believe to be an issue with PuppetDB, was that overnight our Puppetmaster process increased it's RAM usage consistently until bu the morning it was high enough to stop itself from successfully updating it's own catalogue. After stopping the process and letting it release it's resources it seemed to keep itself under control again and right up until now, 10PM the following night, it seems to be working fine so maybe it was just a one-off glitch but will have to keep it in mind in the next few weeks.

Not related to either of the above points, but one issue had to deal with lately was the particular syntax for selecting an array item with Puppet.

If it is being used in an ERB template the correct format is <%= @array_name [0] %> The important part being the space between the array name and the index. If this space does not exist, then the parser will not be able to read the variable and will leave it blank.

If the variable is being used via string interpolation, the correct format is $variable="${arrayname[0]}". The important part being the lack of the space between the array name and the index. I found, especially when using Puppet's host resource, that if you put a space, it will fail to read the variable properly and leave it empty, throwing an error if used as the ip property.

The final scenario I came across, was if you were using string interpolation to generate another array. this one sounds a bit complicated so I'll show an example.

$array1=["a","b","c","d","e"] $array2=["${array1[0]}","${array1[2]}","${array1[4]}"]

Is this situation, it doesn't matter if there is a space or not between the array name and the index.

These aren't complicated things to remember but if you don't know about them and suddenly after an update everything's going crazy and you're staring at one of them going "but it looks perfectly fine" you'll kick yourself if it comes down to a simple space in the wrong place!

I don't think there's anything more to update you guys on.

I will say, that tomorrow (Thursday 24th) there is a webinar conducted by PuppetLabs to explain and explore the new features in Puppet Enterprise 3.3 - Link

There is also a webinar by Atlassian tomorrow too, about using Git for Continuous Integration - Link
