trix trix.uniqueIds.fields = (user) cepNode.timeframe.limit = (5 seconds)

The complex event will be closed after limit-Time has expired

* in log.audit | 

trix trix.uniqueIds.fields = (user) cepNode.event.timeframe.limitFromStart = (10 minutes)

Only events which are less than limitTimeFromStart from the first event will be added to the transaction.

Max number of events for each complex event

Start and End conditions.

To filter only the ceps which stand by the start and end conditions, add the following:

 | where hasstartevent = true and hasendevent = true

* in log.audit 

| trix trix.uniqueIds.fields = (user) groups = (Thread) enrichments.message.all = (message) | where cep.message contains exception or error

Filter of CE flows that contains in their message column ‘error’ or ‘exception’.
groups = recommended for columns with short contents that may be used for display of the CE flow (user_name, action, etc.)

enrichment = recommended when there are columns that their contents may contain values to be filtered (errors, exceptions, etc.)

* in log.audit 

| trix trix.uniqueIds.fields = (user) groups = (priority) | where cep.groups = ERROR or FATAL

Filter of CE flows that their priority column equals ‘ERROR’ or ‘FATAL’.

groups = recommended for columns with short contents that may be used for display of the CE flow (user_name, action, etc.)

enrichment = recommended when there are columns that their contents may contain values to be filtered (errors, exceptions, etc.)

enrichments.pid.first = (pid)

enrichments.pid.all = (context)

enrichments.<name>.<type> - allows adding additional columns to the meta of the cep.

name - the name of the output column to use.

type - the type of the extraction, currently can be ‘first’ (extracts the first value it encounters) or ‘all’ (extracts all values) - optional
