The logging functionality of the Windows agent was rewritten. The key features and changes are as follows:

  • The logs are built incrementally over time and rotated up to 5 copies once the log size of 8 MB is reached.
  • The formatting of the log entries has been changed to include a numeric log level (0...7) and an absolute timestamp with the accuracy of milliseconds (instead of a relative time since the agent started).
  • The naming of agent logfiles has been changed: the agent logs to CHECK_MK_AGENT_INSTALL_DIR\log\agent.log which will then be rotated as agent.log.N, N={1...5}
  • Crash info as subsection [[[Check_MK Agent]]] within the section <<<logwatch>>> was removed. Now that the logs are persistent, information about past crashes can be obtained in the logs.
  • Debug log entries are enabled by setting crash_debug = yes in the global section of check_mk.ini.
  • The names of the various logfiles no longer appear in the output of section Check_MK when crash_debug = yes.
