Title: BI state computation: Removed superfluous and expensive livestatus queries
Component: BI
Level: 1
Class: Bug fix
Version: 2.1.0p31
It is possible to restrict the number of computed BI aggregation via filters.
If a filter was specified and no matching aggregation was found, a livestatus query over all aggregations was generated and sent to the core.
A huge response came back to the apache server, which dutifully parsed the response and threw it straight into the bin.

Title: Legacy check_bi_aggr check: Improved performance
Component: BI
Level: 1
Class: Bug fix
Version: 2.1.0p31
The changeover from the (now deprecated) webapi to the REST API introduced a performance problem.
Instead of fetching/computing the state of the single aggregation, all aggregations were computed.
This lead to apache performance problems, especially in environments with a large amount of aggregations.

Title: omd cleanup: Use package manager search without path
Component: RPM Packaging
Level: 1
Class: Bug fix
Version: 2.1.0p31
The real path (canonical path, eliminating any symbolic links ) was used
before, leading to unfound packages in special situations.
We now use "dpkg -l" and "rpm -qa" to find installed packages. A path is not
needed any more.

Title: Fix the dataset for specific "Site/Host overview" dashlets
Component: Multisite
Level: 1
Class: Bug fix
Version: 2.3.0b1
In distributed setups, several dashboards showed the "Site overview" dashlet where the "Host overview" makes more sense.
This is fixed to always showing hosts, i.e. the "Host overview" dashlet in the following dashboards:
LI: all cloud VM dashboards (AWS, Azure, GCP)
LI: most Kubernetes dashboards (Cluster, Deployment, DaemonSet, StatefulSet, Namespace)
LI: site specific dashboards titled: "Site dashboard <tt>site_name</tt>"

Title: omd_diskusage: Seemingly random crashes
Component: Checks & agents
Level: 1
Class: Bug fix
Version: 2.3.0b1
This fixes a seemingly random crash of the plugin <i>Checkmk: Site disk usage</i>.
The plugin would crash if the <tt>du</tt> command on the sites home directory failed.
We now rather omit the metric than crash in this case.

Title: ntop_alerts: populate alert type dropdown list in alerts dashboards
Component: cmc
Level: 3
Class: Bug fix
Version: 2.3.0b1
This werk fixes an issue with the alert type dropdown menu in the alerts
dashboards. Previously, it was only populated with All, meaning you
couldn't filter the alerts on alert type. Now the dropdown is populated
with all possible alert type values.
