Enabled
Detects that Worker input SVN queue is very large (greater than 100MB). This indicates that the workers are falling behind in handling SVN files from collectors or from the parser modules. Check the SVN installation.

See if any FortiSIEM process is taking up excessive CPU/memory resources on Worker nodes. Consider adding more workers and/or adding resources to workers. Make sure there are no bottlenecks in storage insertion.
If the following pattern or patterns match an ingested event within the given time window in seconds, trigger an incident.
600 seconds
If the following defined pattern/s occur within a 600 second time window.
AOLargeSVNQueue
This is the named definition of the event query, this is important if multiple subpatterns are defined to distinguish them.
This is the query logic that matches incoming events
eventType = "PH_EVT_HANDLER_SVN_QUEUE_WARNING"
This defines how matching events are aggregated, only events with the same matching attribute values are grouped into one unique incident ID
hostName
This is most typically a numerical constraint that defines when the rule should trigger an incident
COUNT (*) >= 1 AND AVG(totBytes64) > 104857600
This section defines which fields in matching raw events should be mapped to the incident attributes in the resulting incident.
The available raw event attributes to map are limited to the group by attributes and the aggregate event constraint fields for each subpattern
hostName = AOLargeSVNQueue.hostName,
totBytes64 = AOLargeSVNQueue.AVG(totBytes64)
