Checkmk Werk 14721: Crash using the cmk_site_statistics (core PIDs) filter

ID: 14721 Title: Crash using the cmk_site_statistics (core PIDs) filter Component: Multisite Level: 1 Class: Bug fix Version: 2.2.0i1 When using the cmk_site_statistics (core PIDs) filter with no monitoring data present the view would crash. Note: This filter is not intended to be used in views and should only be used in host and service problem graphs. But due to compatibility the filter is not removed from view filters. Now the view no longer crashes but rather displays a warning.
