Verify the Database Agent Installation

This page describes how to verify the Database Agent installation.

Review the Agent Logs

After a successful install, your agent logs, located at <db_agent_home>/logs, should contain this message:

Started AppDynamics Database Agent Successfully

If the agent log file is not present, the Database Agent may not be accessing the Database Agent command properties. To troubleshoot, check the application server log file where STDOUT is logged. It will have the fallback log messages, useful for troubleshooting the agent.
