Daemon component capable of storing IDEA messages into persistent storage. Currently only PostgreSQL database is supported.

It is dependent on services of following modules:

The implementation is based on pyzenkit.zendaemon.ZenDaemonComponent.

cbk_event_database_commit(daemon, args)[source]

Check, whether there are any messages waiting to be committed for greater than configured time period. Commit them if necessary to avoid loss of data.

cbk_event_log_statistics(daemon, args)[source]

Periodical processing statistics logging.

cbk_event_message_process(daemon, args)[source]

Store the message into the persistent storage.

cbk_event_start(daemon, args)[source]

Start the component.

cbk_event_stop(daemon, args)[source]
