check_patroni 2.1.0 - 2024-10-28

Fixed

• cluster_has_replica now properly accounts for standby leaders (#72, reported by @MLyssens)

Misc

• Update the tests and the documentation to reflect that master is replaced by
  primary everywhere it's visible in Patroni. We didn't use the term so there
  is nothing to change in our code.

check_patroni 2.0.0 - 2024-04-29

Notice

While fixing cluster_has_replica, the definition of a healthy replica was
changed. It's more restrictive now, hence the jump from v1 to v2.

Changed

• In cluster_node_count, a healthy standby, sync replica or standby leaders cannot be "in
  archive recovery" because this service doesn't check for lag and timelines.

Added

• Add the timeline in the cluster_has_replica perfstats. (#50)
• Add a mention about shell completion support and shell versions in the doc. (#53)
• Add the leader type and whether it's archiving to the cluster_has_leader perfstats. (#58)

Fixed

• Add compatibility with requests
  version 2.25 and higher.
• Fix what cluster_has_replica deems a healthy replica. (#50, reported by @mbanck)
• Fix cluster_has_replica to display perfstats for replicas whenever it's possible (healthy or not). (#50)
• Fix cluster_has_leader to correctly check for standby leaders. (#58, reported by @mbanck)
• Fix cluster_node_count to correctly manage replication states. (#50, reported by @mbanck)

Misc

• Improve the documentation for node_is_replica.
• Improve test coverage by running an HTTP server to fake the Patroni API (#55
  by @dlax).
• Work around old pytest versions in type annotations in the test suite.
• Declare compatibility with click version 7.1 (or higher).
• In tests, work around nagiosplugin 1.3.2 not properly handling stdout
  redirection.

check_patroni 1.0.0 - 2023-08-28

check_patroni is now tagged as Production/Stable.

Added

• Add sync_standby as a valid replica type for cluster_has_replica. (contributed by @mattpoel)
• Add info and options (--sync-warning and --sync-critical) about sync replica to cluster_has_replica.
• Add a new service cluster_has_scheduled_action to warn of any scheduled switchover or restart.
• Add options to node_is_replica to check specifically for a synchronous (--is-sync) or asynchronous node (--is-async).
• Add standby-leader as a valid leader type for cluster_has_leader.
• Add a new service node_is_leader to check if a node is a leader (which includes standby leader nodes)

Fixed

• Fix the node_is_alive check. (#31)
• Fix the cluster_has_replica and cluster_node_count checks to account for
  the new replica state streaming introduced in v3.0.4 (#28, reported by @log1-c)

Misc

• Create CHANGELOG.md
• Add tests for the output of the scripts in addition to the return code
• Documentation in CONTRIBUTING.md
