Generating logs for troubleshooting (PHP)

Problem

You encounter problems with your New Relic for PHP installation but are not sure what is the cause.

Solution

Monitoring your New Relic logs may help diagnose the problem. The New Relic PHP agent and daemon have their own logs. To monitor the logs:

1. Check both logs for content:
   • Default agent log location: /var/log/newrelic/php_agent.log
   • Default daemon log location: /var/log/newrelic/newrelic-daemon.log
2. Set the log level for the agent to verbosedebug and set the log level for the daemon to debug. For more information:
   • Setting the agent loglevel to verbosedebug
   • Setting the daemon loglevel to debug
3. Restart your app.
4. Collect 5 to 10 minutes of log time with your log level set to the appropriate values.
5. Examine your logs and use the information to diagnose the problem.
6. When you are finished troubleshooting, reset the logs' levels. Do not keep them at verbosedebug or debug.
