traffic_crashlog [options]


traffic_crashlog is a helper process that catches Traffic Server crashes and writes a crash report log to the logging directory. Other than for debugging or development purposes, traffic_crashlog is not intended for users to run directly.

When traffic_server starts, it will launch a traffic_crashlog process and keep it stopped, activating it only if a crash occurs.


--host TRIPLE

This option specifies the host triple for the process that traffic_crashlog should examine. If a supported host triple is specified, traffic_crashlog expects to receive a siginfo_t structure on it’s standard input, followed by a ucontext_t.

--target PID

Specifies the process ID of the crashing traffic_server process. If this option is not specified, traffic_crashlog assumes it should examine it’s parent process.


This option causes traffic_crashlog to log the name of the crash log it creates to the system log.


This option enables debugging mode. In this mode, traffic_crashlog emits the log to it’s standard output.


This option causes traffic_crashlog to stop itself immediately after it is launched. traffic_server will allow it to continue only when a crash occurs.


traffic_crashlog makes use of various Traffic Server management APIs. If traffic_manager is not available, the crash log will be incomplete.

traffic_crashlog may generate a crash log containing information you would rather not share outside your organization. Please examine the crash log carefully before posting it in a public forum.
