TRAFFIC_MANAGER(8) | Apache Traffic Server | TRAFFIC_MANAGER(8) |
NAME¶
traffic_manager - Traffic Server process manager
DESCRIPTION¶
The file to which the stdout stream for traffic_manager will be bound.
The file to which the stderr stream for traffic_manager will be bound.
SIGNALS¶
- SIGHUP
- This signal causes a reconfiguration event, equivalent to running traffic_ctl config reload.
- SIGINT, SIGTERM
- These signals cause traffic_manager to exit after also shutting down traffic_server.
- SIGUSR2
- This signal causes the traffic_manager and traffic_server processes to close and reopen their file descriptors for all of their log files. This allows the use of external tools to handle log rotation and retention. For instance, logrotate(8) can be configured to rotate the various Apache Traffic Server™ logs and, via the logrotate postrotate script, send a -SIGUSR2 to the traffic_manager process. After the signal is received, Apache Traffic Server™ will stop logging to the now-rolled files and will reopen log files with the originally configured log names.
EXPONENTIAL BACK-OFF DELAY¶
If traffic_server has issues communicating with
traffic_manager after a crash, traffic_manager will retry to
start traffic_server using an exponential back-off delay, which will
make traffic_manager to retry starting traffic_server from
1s until it reaches the max ceiling time. The ceiling time is
configurable as well as the number of times that traffic_manager will
keep trying to start traffic_server. A random variance will be
added to the sleep time on every retry
NOTE:
