Monitor Correlation rules

Cortex Cloud audits all correlation executions in the correlations_auditing dataset. The dataset records the query initiation times, end times, retry attempts, failure reasons, and other useful metrics. .

In the correlations_auditing dataset, audit entries are added as follows:

• The rule starts executing. This is audited with the status of Initiated or Initiated Manually.
• The rule completes successfully. This is audited as Completed.
• The rule completes with errors. This is audited as Error.

In the dataset, the Query start time and Query end time indicate the timeframe of the data that was queried. The actual start and end times of the correlation rule execution are recorded in the _time field for the Initiated and Completed entries.

Field descriptions for the correlations_auditing dataset

The following table describes the fields in the correlations_auditing dataset:

Field	Description
_time	Timestamp of the audit. For entries with an Initiated or Initiated Manually status, this is the start time of the correlation rule execution. For entries with a Completed or Error status, this is the end time of the rule execution.
_id	Unique identifier of the audit entry.
Rule ID	Unique identification number for the correlation rule.
Name	Correlation rule name.
Status	The status of the correlation rule query. Possible values are Initiated, Initiated Manually, Completed, and Error.
Query start time	The start time of the query timeframe.
Query end time	The end time of the query timeframe.
Time frame	Time frame for the query.
Failure reason	For correlation rules with errors, this field displays the error message.
Retry attempts	Number of retry attempts before the query initiated or failed to run.
Schedule	Scheduled frequency to execute the correlation rule.
Rule creation time	Date and time that the correlation rule was created.
Rule modification time	Date and time that the correlation rule was last modified.
Description	Description of the correlation rule.
Severity	Defined severity of the correlation rule.
Dataset	Target data set, as defined in the correlation rule
Suppression status	Whether issue suppression is Enabled or Disabled.
Suppression duration	Duration for which to ignore additional events that match the issue suppression criteria.
Suppression fields	Fields on which the issue suppression is based.
Timezone	Timezone on which the scheduled frequency is based.
