Processing Action Triggers

To run action triggers, an Evergreen administrator will need to run the trigger processing script. This should be set up as a cron job to run periodically. To run the script, use this command:

/openils/bin/ --process-hooks --run-pending

You have several options when running the script:

  • --run-pending: Run pending events to send emails or take other actions as specified by the reactor in the event definition.

  • --process-hooks: Create hook events

  • --osrf-config=[config_file]: OpenSRF core config file. Defaults to: /openils/conf/opensrf_core.xml

  • --custom-filters=[filter_file]: File containing a JSON Object which describes any hooks that should use a user-defined filter to find their target objects. Defaults to: /openils/conf/action_trigger_filters.json

  • --max-sleep=[seconds]: When in process-hooks mode, wait up to [seconds] for the lock file to go away. Defaults to 3600 (1 hour).

  • --hooks=hook1[,hook2,hook3,…​]: Define which hooks to create events for. If none are defined, it defaults to the list of hooks defined in the --custom-filters option. Requires --process-hooks.

  • --granularity=[label]: Limit creating events and running pending events to those only with [label] granularity setting.

  • --debug-stdout: Print server responses to STDOUT (as JSON) for debugging.

  • --lock-file=[file_name]: Sets the lock file for the process.

  • --verbose: Show details of script processing.

  • --help: Show help information.


  • Run all pending events that have no granularity set. This is what you tell CRON to run at regular intervals.

    perl --run-pending
  • Batch create all "checkout.due" events

    perl --hooks=checkout.due --process-hooks
  • Batch create all events for a specific granularity and to send notices for all pending events with that same granularity.

    perl --run-pending --granularity=Hourly --process-hooks
