Event processing

When hits arrive in the Short Term Canister, events are evaluated, and any resulting actions are taken.

In the Canister report

  • Review the number of Non Evaluated Hits.
  • Compare the above value to the rate at which hits are entering the Canister. This information is in the DecoupleEx report.
  • If the non-evaluated hits constitutes more than a few seconds of data entering the Canister, the problem is usually associated with event processing. In most cases, the source of the issue is that events have been added or changed in the system to cause the processing backlog.
  • The solution is to increase the number of Hit Processor or Session Processor threads if resources are available. See Hit Processors.
