openITCOCKPIT 3.3 released

Today we have released the next version of openITCOCKPIT 3.3.

System health overview

One of the new features is the System health overview. A cron job is monitoring all important background processes and system metrics. As soon as an issue is detected, System health overview will change its state into warning or critical depending on the possible impact of the issue.

Performance improvement

To avoid complete page reloads, we refactored high-traffic pages like the host and service overviews with AngularJS. Due to the new frontend framework, filter requests or pagination are completely handled by an API request instead of an complete page reload.

Also, the MySQL database is a common bottleneck. With the new version, we added a Redis in-memory database that will cache heavy operations like calculating user permissions.

Enhanced filters

To be able to add more filter options, we developed a completely new filter component and added it to the most visited pages. With every new version, the new filter will be added to more pages.

In the Log entries overview it is now possible to filter by one or more hosts. This makes debugging easier in case of an error, for example if you want to track why a notification was suppressed.

Design Module

Is openITCOCKPIT theme too light or too dark? We adjusted the Design Module and the inbuilt themes, so it’s easier to create your own style.

You now also have the option to add your logo to the top menu bar.
