Version 1.1.3 of Check_MK introduces a new web GUI for displaying monitoring status information called Multisite. It has grown out of "Multiadmin" but is a complete rewrite and goes way beyond.
Multisite brings three major innovations:
Besides that, since Multisite is based on Livestatus, you will experience that it is very fast in large installations with many hosts and services. The response time for most views is almost independent of the size of your monitoring environment.
Multisite allows each user to customize the builtin views or create completely new views. This is done in the GUI by flexibly combining datasources, layouts, filters, sortings, groupings, column-painters and inter-view-links. The idea behind is, that the administrators of the monitoring system should be able to create custom views for their users or customers, while those are presented a GUI as simple as possible.
The elements of views - like layouts, filters and so on - can be extended via Python using a plugin concept.
3. Distributed monitoring
Multisite is very useful in single site installations of Nagios. The most far-reaching innovation, however, is its support for distributed monitoring via Livestatus.
The basic idea behind a Check_MK Multisite setup for distributed monitoring ist that you do not pump all check data produced by your remote sites into one centralized Nagios (using NSCA or similar tools), but that leave your data where it is. Instead, what is centralized is just the visualization. The Multisite GUI retrieves live data from the remote sites on demand via MK Livestatus and merges it into one logical view. The visualization can even be run without a central Nagios server.
This scheme has various advantages, amongst which are:
4. Status of the current release
Please note, that the current release of Multisite is still not considered stable. That means that:
However, Multisite is already very useful and can be used in combination with the classical Nagios web GUI.
