What's new

What's New in Version 0.0.8

  • Add Dependency object for advanced host/service dependency definition
  • Add optional IcingaNodeName for cluster feature
  • Populate check_source attribute with the checker's node name
  • Cluster supports recursive config includes
  • Add Cluster health check
  • Add more performance data to the Icinga health check
  • Add IcingaStatusWriter feature writing a status json file
  • Smoother pending service checking during startup
  • Reduce virtual memory usage
  • Stack traces include file names and line numbers
  • Treat script variables as constants preventing override
  • Fix pending services are being checked with the retry interval
  • DB IDO: Fix deleted objects are not marked as is_active=0
  • DB IDO: additional fields for cluster/checker nodes

Changes

  • {host,service}_dependencies attributes have been changed to Dependency objects supporting new attributes: disable_checks, disable_notifications, state_filter, period. For better readability, there is parent_service and child_service for example.

Note

Update your existing configuration!

What's New in Version 0.0.7

  • DB IDO performance improvements on startup
  • Fix notification_id handling in DB IDO
  • More automated tests (based on the Vagrant VM)
  • New documentation chapters

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 separator. 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}
  • Lots of bugfixes and performance improvements
  • 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

  • StatusDataWriter and ExternalCommandListener (former Compat) and CompatLogger (former CompatLog) for status.dat/objects.cache/icinga2.cmd/icinga.log for Icinga 1.x Classic UI support
  • IdoMysqlConnection and ExternalCommandListener for Icinga 1.x Web
  • IdoMysqlConnection for Icinga 1.x Reporting, NagVis
  • LivestatusListener for addons using the livestatus interface (history tables tbd)
  • PerfDataWriter for graphing addons such as PNP/inGraph/graphite (can be loaded multiple times!)
  • GraphiteWriter for sending metrics 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
  • SyslogLogger, FileLogger and ConsoleLogger for different types of logging
  • Domain support for distributed cluster environments
  • Config migration script supporting easier migration from Icinga 1.x configuration
  • Reviewed configuration options, additional attributes added
  • Enhanced ITL, added sample configuration
  • Enable/Disable Icinga 2 features on CLI
  • Documentation using Markdown (Getting Started, Monitoring Basics, Object Types, Icinga Template Library, Advanced Topics, Migration from Icinga 1.x, Differences between Icinga 1.x and 2, Vagrant Demo VM)
  • Vagrant Demo VM supported by Puppet modules installing RPM snapshots for Icinga 2, Icinga 1.x Classic UI and Web
