All Event processing logs can be found at below path. This will have event spy logging info also, if enabled.
<DCF-Install>/Event-Processing/Event-Processing-Manager/<INSTANCE>(ex:smarts-notifs-events)/logs/processing-0-0.log
Latest processing log name will have "-0-0" appended to its name like above.
To enable logging, change the event processing configuration to push events to event spy like below. And after changing the configuration, operator need to restart the service to see the logging info in processing-0-0.log.
Edit below file as specified below:
File : <DCF-Install>/Event-Processing/Event-Processing-Manager/<INSTANCE>(smarts-notifs-events)/conf/processing.xml --- <processing-element name="Smarts" enabled="true" config="Smarts-Listener/smarts-notifs-events/conf/smarts-listener.xml" data="KAFKA EVENT-SPY"/> ---
For example: Ex: "smarts-notifs-events" is installed management pack name in below example.
To check the status of the installed services:
<DCF-Install>/bin/manage-modules.sh service status all …. * Checking 'event-processing-manager smarts-notifs-events'... [ running ]
To restart the particular service:
<DCF-Install>/bin/manage-modules.sh service restart event-processing-manager smarts-notifs-events * Stopping 'event-processing-manager smarts-notifs-events'... [ OK ] * Starting 'event-processing-manager smarts-notifs-events'... [ OK ]
