Signals
- SIGHUP
-
This signal causes a reconfiguration event, equivalent to running traffic_ctl config reload.
- SIGINT, SIGTERM
-
These signals cause
traffic_managerto exit after also shutting downtraffic_server.
SIGUSR2-
This signal causes the
traffic_managerandtraffic_serverprocesses 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 thetraffic_managerprocess. 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:
