Restarting the performance monitoring tool

If the pmsensor or pmcollector package is upgraded, the corresponding daemon is stopped and needs to be started again.

To start the sensor on a particular node, use the systemctl start pmsensors command. To start the collector, use the systemctl start pmcollector command.

If the ZIMonCollector.cfg file is changed, the pmsensors service on that node needs to be restarted with systemctl restart pmcollector command.

With manual configuration, if the ZIMonSensors.cfg file is changed, the pmsensors service on that node needs to be restarted by using the systemctl restart pmsensors command. No action is necessary for IBM Storage Scale managed sensor configuration.

To restart the collector, use the systemctl restart pmcollector command.

Note:

This command works only for systems that use systemd scripts. On systems that use sysv initialization scripts, you must use the service pmsensors and service pmcollector command instead of the systemctl command.
