v1.2.0

a0a65af

Icinga DB v1.2.0

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
