Use the steps in these documents to enable debug logging for the various components of Symantec Endpoint Protection Manager (SEPM). You can enable logging for all components of the manager, or just the specific components you need to.
Apache server debug logs are needed to trace Symantec Endpoint Protection Webserver service failures/crashes. They are also useful for debugging content distribution from managers to their Symantec Endpoint Protection clients, client-to-server communications failures, or reporting server failures. For more information, see Enabling Apache server debugging for the Endpoint Protection Manager.
