ZendHQ 2.2.0

New features

  • Added the zendhqctl monitoring history command that can be used to query monitoring issues from the monitoring database.

    The command implements list and print sub-commands for listing and printing monitoring issues.

  • Added the monitor.aggregate_ttl directive to the ZendHQ daemon's configuration file that can be used to set the time-to-live value for aggregated monitoring issues.

    The default value is 300 (5 minutes). If a monitoring event repeats within the time-to-live value, then the event is aggregated into a single monitoring issue.

    The monitoring issues aggregation can be enabled with the monitor.aggregate_events directive.

Changes

  • The mon.get_issues JsonRPC method now has an additional filter parameter that can be used to filter issues by severity, event type, time, and rule name.

  • The mon.get_issues JsonRPC method now has an additional last_id parameter that can be used to specify the last seen issue ID value for implementing pagers.

Bug fixes

  • Fixed a bug that caused Job Queue queue starvation if a job was scheduled to run in the far future (24 days and more).

  • Fixed a bug in the ZendHQ daemon's monitoring module that did not store custom monitoring event user data to the database. The user data provided with zend_monitor_custom_event() and zend_monitor_custom_event_ex() functions is now properly stored in the monitoring database.

New API and database schema versions

  • JsonRPC session namespace API version is now 1.10.

  • JsonRPC mon namespace API version is now 1.4.

  • Monitoring database schema version is now 2.2.
