Polling HPCC system for events

Questions around writing code and queries

Wed Mar 24, 2021 5:25 pm Change Time Zone

Is there a way to poll the HPCC system for all the events that it is currently monitoring? An ECL job may execute a WAIT action looking for an event with no duration specified, so essentially HPCC will be monitoring for that event forever. Same thing with monitoring for a file. There doesn't seem to be a way to remove said monitoring or to even see if that monitoring is active or not. I can imagine that over time the system could get bogged down trying to monitor for items that are no longer going to trigger the events being monitored for.

John,

When you open ECL Watch, it opens on the Activity tab of that home page.

Just to the right of that Activity tab is the Event Scheduler tab, which lists all the workunits that are currently waiting for events.

On that Event Scheduler tab you can:
  • use Push Event to manually invoke an event instance (for testing purposes usually)
  • select any workunit there and Deschedule that open workunit.
  • open any workunit there and Deschedule, or Abort that open workunit.
HTH,

Richard
