Automated downtimes for Checkmk

| ActiveCheck-Plugin for automatically setting downtimes on host/services based on other hosts/service.

If reinstalling the MKP again after a CMK 2.4 update, be sure to re-save existing old rules, if this MKP was in use in earlier versions.

Requirements

• CMK 2.2, 2.3, (2.1 should work but not tested): use plugin version 2.0.x
• CMK 2.4+: use plugin versions 2.4+
• CRE/Raw-edition is sufficent
• Distributed setups are supported

Releases

See exchange.checkmk.com

Changes

• 2.4.5+:

• Fixes in server-side-calls + rule-migration

• Support "hl:" in host-regex-field for manuel target-selection: With this prefix host-labels instead hostnames are used for search

• 2.4.0:

  • !Consider this version as Beta!
  • Screenshot your rules before updating CMK
  • Support for CMK 2.3+ API, tested on CMK 2.4.
  • If plugin is installed/updated afteri a CMK-Update resave the rules (or run cmk-update-config again)

• 2.0.8:

  • Improve support for macros, also on RAW-Editions.
  • Introduce Regex-Replace-Support to allow transform content of macros in rules fields. Expample: Tunnel (?:{{$HOSTNAME$~~([0-9a-z]+).*~~\1}})
    In this sample
    • the preprocessor extracts the content of {{ }}
    • it splits the content by ~~ into 3 parts
      • source macro
      • regex to match the source macro and define capture groups
      • output of the capture group(s)
    • for a $HOSTNAME$ like myhost4711.my.domain the output of {{ }} is myhost4711
    • the resulting rule is Tunnel (?:myhost4711) which allows to match a tunnel like Tunnel MYHOST4711

• 2.0.7:

  • Initial support for a gracetime before removing downtimes after prerequisites are no longer met

• 2.0.6:

  • Spread cache refreshes and other cache improvements

• 2.0.5:

  • Add support for reading the estimated downtime from perfdata. In the rule it is required to define service-output-regex (at minimum ".+") Then specify the perfdata-names which contain unix-timestamps. See the inline-help! Again a 10 minute gracetime before/after the specifed timestamps is added.
  • Fixes for retaining CMK 2.2 compat 2.0.3:
  • Fix param eval for case-insensitive 2.0.2:
  • Improve refreshing of cache in certain circumstances
  • Fixes/Improvements in ruleditor (Thanx to TuneFish41)
