salt.modules.trafficserver

Apache Traffic Server execution module.

traffic_ctl is used to execute individual Traffic Server commands and to script multiple commands in a shell.

salt.modules.trafficserver.alarms()

List all alarm events that have not been acknowledged (cleared).

salt '*' trafficserver.alarms

salt.modules.trafficserver.bounce_cluster()

Bounce all Traffic Server nodes in the cluster. Bouncing Traffic Server shuts down and immediately restarts Traffic Server, node-by-node.

salt '*' trafficserver.bounce_cluster

salt.modules.trafficserver.bounce_local(drain=False)

Bounce Traffic Server on the local node. Bouncing Traffic Server shuts down and immediately restarts the Traffic Server node.

drain

This option modifies the restart behavior such that traffic_server is not shut down until the number of active client connections drops to the number given by the proxy.config.restart.active_client_threshold configuration variable.

salt '*' trafficserver.bounce_local
salt '*' trafficserver.bounce_local drain=True

salt.modules.trafficserver.clear_alarms(alarm)

Clear (acknowledge) an alarm event. The arguments are “all” for all current alarms, a specific alarm number (e.g. ‘‘1’‘), or an alarm string identifier (e.g. ‘’MGMT_ALARM_PROXY_CONFIG_ERROR’‘).

salt '*' trafficserver.clear_alarms [all | #event | name]

salt.modules.trafficserver.clear_cluster()

Clears accumulated statistics on all nodes in the cluster.

salt '*' trafficserver.clear_cluster

salt.modules.trafficserver.clear_node()

Clears accumulated statistics on the local node.

salt '*' trafficserver.clear_node

salt.modules.trafficserver.match_config(regex)

Display the current values of all configuration variables whose names match the given regular expression.

New in version 2016.11.0.

salt '*' trafficserver.match_config regex

salt.modules.trafficserver.match_metric(regex)

Display the current values of all metrics whose names match the given regular expression.

New in version 2016.11.0.

salt '*' trafficserver.match_metric regex

salt.modules.trafficserver.offline(path)

Mark a cache storage device as offline. The storage is identified by a path which must match exactly a path specified in storage.config. This removes the storage from the cache and redirects requests that would have used this storage to other storage. This has exactly the same effect as a disk failure for that storage. This does not persist across restarts of the traffic_server process.

salt '*' trafficserver.offline /path/to/cache

salt.modules.trafficserver.read_config(*args)

Read Traffic Server configuration variable definitions.

New in version 2016.11.0.

salt '*' trafficserver.read_config proxy.config.http.keep_alive_post_out

salt.modules.trafficserver.read_metric(*args)

Read Traffic Server one or more metrics.

New in version 2016.11.0.

salt '*' trafficserver.read_metric proxy.process.http.tcp_hit_count_stat

salt.modules.trafficserver.refresh()

Initiate a Traffic Server configuration file reread. Use this command to update the running configuration after any configuration file modification.

The timestamp of the last reconfiguration event (in seconds since epoch) is published in the proxy.node.config.reconfigure_time metric.

salt '*' trafficserver.refresh

salt.modules.trafficserver.restart_cluster()

Restart the traffic_manager process and the traffic_server process on all the nodes in a cluster.

salt '*' trafficserver.restart_cluster

salt.modules.trafficserver.restart_local(drain=False)

Restart the traffic_manager and traffic_server processes on the local node.

drain

This option modifies the restart behavior such that traffic_server is not shut down until the number of active client connections drops to the number given by the proxy.config.restart.active_client_threshold configuration variable.

salt '*' trafficserver.restart_local
salt '*' trafficserver.restart_local drain=True

salt.modules.trafficserver.set_config(variable, value)

Set the value of a Traffic Server configuration variable.

variable

Name of a Traffic Server configuration variable.

value

The new value to set.

New in version 2016.11.0.

salt '*' trafficserver.set_config proxy.config.http.keep_alive_post_out 0

salt.modules.trafficserver.shutdown()

Shut down Traffic Server on the local node.

salt '*' trafficserver.shutdown

salt.modules.trafficserver.startup()

Start Traffic Server on the local node.

salt '*' trafficserver.start

salt.modules.trafficserver.status()

Show the current proxy server status, indicating if we’re running or not.

salt '*' trafficserver.status

salt.modules.trafficserver.zero_cluster()

Reset performance statistics to zero across the cluster.

salt '*' trafficserver.zero_cluster

salt.modules.trafficserver.zero_node()

Reset performance statistics to zero on the local node.

salt '*' trafficserver.zero_cluster
