Checkmk Werk 14957: fileinfo: Crash on negative timespans

ID: 14957 Title: fileinfo: Crash on negative timespans Component: Checks & agents Level: 1 Class: Bug fix Version: 2.2.0i1 When monitoring files/filegroups with service monitoring rules <i>Size and age of single files</i> or <i>Size, age and count of file groups</i> (i.e., all services basing on the <i>fileinfo</i> agent section, not on the mk_filestats agent plugin), the service evaluation could fail with a crash report containing the error "Cannot render negative timespan". This happened very rarely, and if it did, it was temorary (for one check period). Since the fix consists of a change in the agent section evaluation, you'll have to update agents to apply it on affected systems.
