# traffic\_crashlog(8)

Traffic Server crash log helper

## NAME

traffic\_crashlog - Traffic Server crash log helper

## SYNOPSIS

**traffic\_crashlog** \[options\]

## DESCRIPTION

**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.

## OPTIONS

- **--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.

- **--syslog**

  This option causes **traffic\_crashlog** to log the name of the crash log it creates to the system log.

- **--debug**

  This option enables debugging mode. In this mode, **traffic\_crashlog** emits the log to it's standard output.

- **--wait**

  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.

## CAVEATS

**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.
