About Icinga 2

What is Icinga 2?

Icinga 2 is an enterprise-grade open source monitoring system which keeps watch over networks and any conceivable network resource, notifies the user of errors and recoveries and generates performance data for reporting. Scalable and extensible, Icinga 2 can monitor complex, large environments across dispersed locations.

Support

Support for Icinga 2 is available in a number of ways. Please have a look at the support overview page at [https://support.icinga.org].

What's New in Version 0.0.6

  • Scheduled Downtimes as configuration object (also known as "Recurring Downtimes").
  • Log command arguments
  • Performance improvements for the config compiler
  • Config validation provides stats at the end
  • icinga2-enable-feature lists already enabled features
  • Add support for latency statistics to IcingaCheckTask
  • Implement support for using custom attributes as macros
  • StatusDataWriter update interval as config attribute
  • Improve performance with fetching data for status.dat/objects.cache, DB IDO and Livestatus
  • Livestatus History Table performance improvements

Changes

  • Generated object names (host with services array) use an exclamation mark instead of a colon as seperator. State file objects with downtimes, comments, etc are invalid (unknown) for that reason.
  • Script variables are set using 'var' and 'const' instead of the previous 'set' identifier
  • ITL constants are now embedded in libicinga
  • Removed the ConsoleLogger object and keep the default console log enabled until we daemonize

What's New in Version 0.0.5

  • Cluster: Implement support for CRLs
  • Implement modified attributes
  • Log messages providing more context
  • Default log is a file (rather than syslog)
  • Improve latency after start-up
  • NSCA-ng support for the Vagrant demo VM
  • Configuration: Recursively include configuration files matching a certain pattern
  • IDO: Improve performance
  • Migration: Add fallback for objects.cache instead of cfg_{dir,file}

  • Package fixes (Note: GPG key of packages.icinga.org has been updated)

What's New in Version 0.0.4

  • IDO: PostgreSQL support
  • IDO: implemented options to filter which kind of events are written to the database
  • Livestatus: implemented support for the log and statehist tables
  • Livestatus: implemented regex filters (~ and ~~)
  • Replaced autotools-based build system with cmake
  • Lots of bug fixes and performance improvements

What's New in Version 0.0.3

  • GraphiteWriter for sending metrics to directly to graphite carbon sockets
  • CheckResultReader to collect Icinga 1.x slave checkresults (migrate your distributed setup step-by-step)
  • ClusterListener for real distributed architecture including config and runtime data (checks, comments, downtimes) sync and replay
