Checkmk Werk 10123: Fixed race condition when changing host check command.

by Sven Panne

ID: 10123 Title: Fixed race condition when changing host check command. Component: cmc Level: 2 Class: Bug fix Version: 1.7.0i1 When the kind of a host check command was changed, e.g. from an active check to smart ping, there was a small time window for scheduling to go wrong. This resulted in endless log lines of the form "invalid command line '@foo' for bar", and the only way to resume normal operation was to restart the Checkmk Micro Core, reloading was not enough. This has been fixed.

Checkmk Werk 10122: Fixed performance regression for event console history queries.

by Sven Panne

ID: 10122 Title: Fixed performance regression for event console history queries. Component: Event Console Level: 2 Class: Bug fix Version: 1.7.0i1 The event console history queries had a rather serious performance regression in 1.6.0: For common queries, the EC tries to pre-filter the history via egrep before doing further filtering itself. This pre-filtering was broken due to a typo and has been repaired now.

Checkmk Werk 7287: Fixed incorrect processing of SNMP datasource configuration

by Andreas Boesl

ID: 7287 Title: Fixed incorrect processing of SNMP datasource configuration Component: WATO Level: 2 Class: Bug fix Version: 1.7.0i1 Due to an incorrect old configuration conversion routine the snmp datasource setting for a host was incorrectly set/reset to <tt>No SNMP<tt>. This could be observed on the edit host page, for example. It only applied to hosts where the agent tag group was explicitly set. This incorrectly transformed snmp setting was written back to disk, when the host itself was saved or when there were any changes made in the host tags configuration. Changes in the host tag configuration had a greater impact because they forced a complete rewrite of all host configurations.
