RSyslog Windows Agent 4.1 Released

Adiscon is proud to announce the 4.1 release of MonitorWare Agent.

Rsyslog Windows Agent is now able to reload it’s configuration automatically if enabled (Which is done by the configuration client
automatically on first start). It is not necessary to restart the service manually anymore.

Performance enhancing options have been added into EventLog Monitor V1 and V2 and in File Monitor to delay writing the last record/fileposition back to disk. This can incease performance on machines with a very high eventlog or file load.

Detailed information can be found in the version history below.

Build-IDs: Service, Client


  • Updated to OpenSSL 1.0.2k.
  • Configuration Reload: This is a big new core feature allowing the
    service to reload itself automatically after a configuration changed has
    been detected. The feature can be turned off in General-General Options if
    this new behavior is not wanted. By default auto reload will be enabled.
    The latest Configuration Client is required for the feature to fully work.
  • EventLog Monitor V2: Added new options to delay LastRecord save.
    Enabling this option will improve processing performance of machines with
    a high event volume.
  • EventLog Monitor V1: Added new option to delay LastRecord save. Enabling
    this option will improve processing performance of machines with a high
    event volume.
  • File Monitor: Added new option to delay LastFilePosition save. Enabling
    this option will improve processing performance when processing large
    growing files.
  • FileConfig: Changed datafile saving method, more reliable when the
    service is stopped unintentionally while updating data state files.
  • Send Syslog Action: Added new option to enable/disable UTF8 BOM. Default
    is enabled like before, but it can be disabled now by configuration so the
    message won’t contain the UTF8 BOM.


  • Property Engine: Fixed SystemID and CustomerID properties.v
  • FileConfig: Due a missing property (FilterVersion), some of the global
    conditions in rule filters could not be used. This automatically fixes
    itself next time the configuration is saved with the Client.
  • Debug Logging: Completely rewritten debug output for Rule Engine
    (Filters) for better readability and analysis.
  • Fixed an compatibility issue on Windows 2003/XP (failed to start because
    WSAPoll API is missing).
  • FileConfig: Fixed an issue with invalid linefeeds when using includefile
  • FileConfig: Fixed EnumRegkey emulation causing EventLog Monitor Services
    to load invalid eventlog channels.
  • Debug Logging: Moved RELP Debugging from minimal to internal
  • FileMonitor: Fixed issue rewriting filepointer updates each time when
    wildcards support was enabled.
