user column as a unique key - mandatory

pid column as an optional unique key

* in log.audit | trix trix.uniqueIds.fields = (user) trix.uniqueSubIds.fields = (pid) cep.name=(session id)

The name for each complex event will be determined by the session id value

* in log.audit | trix trix.uniqueIds.fields = (user) trix.uniqueSubIds.fields = (pid) cep.name=(session id) cep.groups=(session id)

groups list will be determined by the session id values

types list will be determined by the thread values

* in log.audit 

| trix trix.uniqueIds.fields = (user) | where cep.time < 10000

Trix events that took more than 10 seconds (time is in milliseconds)

Average, Minimum and Maximum time of the Trix events

* in log.audit | 

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.

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.)

* in log.secure 

| trix trix.uniqueIds.fields = (user+pid) endRule = (message contains Connection closed by invalid user OR Disconnecting invalid user OR Disconnected from invalid) cep.name = User | where cep.endEvent = true

Windows events CEPs - Failed Logon Attempts

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
