KermIT: New filters and Dashboard
KemIT development going ahead adding new functions everyday. Today two new videos showing Tree Filters and Persistent DashBoard.
A problem with big datacenter in the previous KermIT version was all widgets with classed served inside (for example puppet classes widget). If you want to reach a particular class or server you should look for it by hand (search in any folder to find your server). Now you can simply search the resource you need (folder or server name) and you will be pointed out to matching resources.
[video src="http://www.mornati.net/video_kermit/video/KermIT%20-%20Filters%20in%20tree%20views.mp4" width="100%"]
Even if you could move or change dashboard widgets, all mods was not persisted in the previous KermIT version; a simple page refresh restore to default settings. Now any user can personalize the dashboard changing widget position, colors, titles, etc. and all mods will be persisted (any user has a different dashboard). Cookies required to allow this new function.

Stay tuned because we have some other interesting and useful functions... Do you want tp create a new server in a click? You should use KermIT ;)

KermIT: Dynamic Groups for resources
A new interesting feature we are actually coding in KermIT web application is Dynamic Groups. You can define a rule to group servers (and later, all kind of resources) and will be automatically added to this group if they match the rule. In this way, any new server added (or removed) to KermIT network will appear (or disappear) in the correct group with no manual interaction for the admin user.
[video src="http://www.mornati.net/video_kermit/video/KermIT%20-%20Dynamic%20Groups.mp4" width="100%"]
In the video you can see how you can create dynamic groups and how servers are added to a group (with a simple refresh operation) but, as I said, this function is still in development and you can actually create dynamic groups based on faster facts.
Stay tuned for news about this cool feature! :D

KermIT: assign puppet classes to a server within the webui
These days we are working, on the KermIT's master branch, adding some new interersting features (and refactoring lot of our code). Here a video that shows how you can provision the servers, changing the assigned puppet classes directly within the KermIT web interface.
[video src="http://www.mornati.net/video_kermit/video/Kermit-Edit_Puppet_Classes_with_Hiera_backend.mp4" width="100%"]
What you should have is the puppet master configured to use Hiera, that allow you to define the puppet site.pp, not in a statically way, but importing definitions using Hiera. Here my dev file:
node default { include sudo } node centos6 inherits default { hiera_include('centos6.mmornati.lan', '') } node puppet inherits default { hiera_include($hostame, '') }
What will happen when puppet read this file, is a call to hiera to get information using the machine hostname (or the static string 'centos6.mmornati.lan').
To increase the scalability of our infrastructure, KermIT and Hiera store the puppet configuration into a Redis database. So, when you change server information using KermIT, all stuffs are simply stored into Redis db, and, next time puppet agent is fired, it will read the latest configuration from database.
At the moment we don't have a KermIT development RPM, but you can test all these features getting the code directly from github (branch master). On KermIT website an article explains, step by step, how you can install hiera on your system.

Twemcache is the twitter fork of Memcache project released today by Twitter under BSD license. I think, if we need a cache service, this one is largely tested and used with good results :D
Let's test it!
