NAME¶
traffic_cop - Traffic Server watchdog
DESCRIPTION¶
traffic_cop is a watchdog program that is responsible for starting
traffic_manager and
traffic_server and monitoring them for
responsiveness. If either of these processes are determined to be
unresponsive,
traffic_cop will kill and restart them.
On Linux,
traffic_cop will also monitor available memory and swap space,
restarting the watched processes if the available memory falls below a minimum
threshold. The memory thresholds can be configured with the
proxy.config.cop.linux_min_swapfree_kb and
proxy.config.cop.linux_min_memfree_kb variables.
OPTIONS¶
- -d, --debug
- Emit debugging messages.
- -o, --stdout
- traffic_cop ordinarily logs to syslog, however for debugging
purposes, this option causes it to print messages to standard output
instead.
- -s, --stop
- Kill children using SIGSTOP instead of SIGKILL. This option
is primarily for debugging.
- -V, --version
- Print version information and exit.
