Icinga DB Changelog

1.2.1 (2024-12-18)

This is a maintenance release that addresses HA issues and includes a number of other fixes.

Most prominent, crashes caused by an invalid HA state were investigated and fixed mainly by the following changes.

  • Ensure that the crucial HA realization logic is always aborted when its timeout is reached. #800
  • Give up the HA leadership role if it seems another node is also active. #825
  • Reduce database deadlocks in the HA realization domain with exclusive locking. #830

Other notable changes include the following:

  • ACL and database support for Redis®*. #874, icinga-go-library#50, icinga-go-library#52
  • Alter the database schema to allow longer user input. #779, #792, #856
  • Mitigate some NULL values for icingadb-migrate. #767
  • Retry certain database errors for PostgreSQL. icinga-go-library#59
  • Retry Redis® timeout errors for XREAD. icinga-go-library#23
  • Additional tests were written. #771, #777, #803, #806, #807, #808
  • Parts of the code have been moved to our icinga-go-library for use by our other Go daemons. #747
  • Update dependencies. 26 times

Schema

A schema upgrade is available that allows longer user input as listed above. Please follow the upgrading documentation.

1.2.0 (2024-04-11)

This release addresses multiple issues related to fault recoveries, with a particular focus on retryable database errors that may occur when using Icinga DB with database clusters.

Since there may be a large number of errors that are resolved by retrying after a certain amount of time, #698 changed the retry behavior to retry every database-related error for five minutes. This helps Icinga DB survive network hiccups or more complicated database situations, such as working with a database cluster.

The latter was specifically addressed in #711 for Galera Clusters on MySQL or MariaDB by configuring wsrep_sync_wait on used database sessions. Galera users should refer to the Configuration documentation for more details.

In summary, the most notable changes are as follows:

  • Custom Variables: Render large numbers as-is, not using scientific notation. #657
  • Enhance retries for database errors and other failures for up to five minutes. #693, #698, #739, #740
  • MySQL/MariaDB: Use strict SQL mode. #699
  • MySQL/MariaDB Galera Cluster: Set wsrep_sync_wait for cluster-wide causality checks. #711
  • Don't crash history sync in the absence of Redis®*. #725
  • Update dependencies. 27 times

Schema

In addition to mandatory schema upgrades, this release includes an optional upgrade that can be applied subsequently. Details are available in the Upgrading documentation and #656.

All schema changes are listed below:

  • Allow host and service check attempts >= 256. #656
  • Composite INDEX for the history table to speed up history view in Icinga DB Web. #686
  • MySQL/MariaDB: Fix icingadb_schema.timestamp not being Unix time. #700
  • PostgreSQL: Change get_sla_ok_percent to return decimal numbers in SLA overview. #710

1.1.1 (2023-08-09)

This release fixes a few crashes in the Icinga DB daemon, addresses some shortcomings in the database schema, and makes the icingadb-migrate tool handle malformed events and other edge-cases more reliably.

  • Fix a possible crash when the Icinga 2 heartbeat is lost. #559
  • Retry additional non-fatal database errors. #593 #583
  • Make heartbeat compatible with Percona XtraDB Cluster. #609
  • Write a hint for empty arrays/dicts into customvar_flat for Icinga DB Web. #601
  • Warn about unknown options in the daemon config file. #605 #631
  • Don't log a port number for UNIX socket addresses. #542
  • Fix some custom JSON encode functions for null values. #612
  • Documentation: add TLS options to icingadb-migrate example config. #604
  • Documentation: Replace apt-get with apt. #545
  • Update dependencies. #548 #549 #588 #589 #590 #594 #595 #596 #598 #599 #603 #632

Schema

  • Allow longer names for notification objects. #584
  • Add missing indices to hostgroup, servicegroup, and customvar_flat. #616 #617
  • Change sort order of history event types. #626

icingadb-migrate

  • Ignore events that miss crucial information. #551
  • Fix a foreign key error for flapping history with ido.from set. #554
  • Fix a constraint violation for flexible downtimes that never started. #623
  • Show an error for unknown options in the config file. #605

1.1.0 (2022-11-10)

This release adds a tool for migrating history from IDO. Apart from that, it reduces RAM usage and includes updated dependencies.

  • Add icingadb-migrate for migrating IDO history to Icinga DB. #253 #536 #541
  • Reduce RAM usage during full sync. #525
  • Update dependencies. #522 #524 #533 #534 #540
