The SQLcompliance SQL Compliance Manager Agent runs under the SQLcompliance SQL Compliance Manager Agent Service account on each registered SQL Server computer that hosts the audited instances and databases. To audit events, the SQLcompliance SQL Compliance Manager Agent starts SQL Server traces that run on the target SQL Server. Once a trace starts, SQLcompliance copies events from the SQL trace to trace files, providing a raw audit record.

Trace files are stored in the AgentTraceFiles folder under the install directory (C:\Program Files\Idera\SQLcompliance) on the computer that hosts the SQL Server instance. This folder is secured using ACL settings. You can specify a different location for the trace directory.

The SQLcompliance SQL Compliance Manager Agent compresses the trace files and sends them to the Collection Server. After a trace file is successfully sent, the SQLcompliance SQL Compliance Manager Agent deletes the file.

You can configure how the SQLcompliance SQL Compliance Manager Agent manages these trace files. For example, you can set the maximum trace directory size to limit how much storage space is consumed by unprocessed audit data. When the directory size is reached, the SQLcompliance SQL Compliance Manager Agent stops the SQL trace until the existing trace files can be sent to the Collection Server.

By default, the SQLcompliance SQL Compliance Manager Agent communicates with the Collection Server every 5 minutes. This communication is a heartbeat. During a heartbeat, the SQLcompliance SQL Compliance Manager Agent confirms its health and receives audit setting updates. You can manually apply audit setting updates as needed using the Management Console.

If the SQLcompliance SQL Compliance Manager Agent continues to run without a heartbeat, IDERA SQL Compliance Manager considers the agent to be unattended. By setting the unattended time limit, you can control how long traces are allowed to run until SQL Server stops the trace. Use this setting to automatically stop auditing when the SQLcompliance SQL Compliance Manager Agent is not responding or is deleted.

When you deploy the SQLcompliance SQL Compliance Manager Agent, SQLcompliance installs the SQLcompliance SQL Compliance Manager Agent service on the computer hosting the target SQL Server instance. You can install the agent manually through the setup program or dynamically through the Management Console.
