The agent log is located at $<php_agent_install>/logs/agent.log. The log contains the transactions that the agent processes and then sends to the proxy.

The default pattern for agent log naming is the following:

• agent.log : the current log
• agent.log.1 : most recent log
• agent.log.2 : second most recent log
• agent.log.3 : third most recent log
• agent.log.4 : fourth most recent log
• agent.log.5 : fifth recent log.

The agent creates and rotates a maximum of six log files. Maximum log size is 20 MB, which gives you a maximum of the most recent 120 MB of log data at one time.

The proxy log is located at $<php_agent_install/logs/proxy_$date.log. This log contains the transactions that the proxy accepts from the agent and then sends to the Controller. See Proxy Logging and Dynamic Language Agent Proxy.
