4. The collectd IPI configuration:
# cat /etc/collectd/collectd.conf.d/ipmi.conf
Code
LoadPlugin ipmi
<Plugin "ipmi">
NotifySensorAdd false
NotifySensorRemove true
NotifySensorNotPresent false
SELEnabled false
SELClearEvent false
</Plugin>5. Restart collectd.service
# systemctl restart collectd.service
# systemctl status collectd.service -n 100
Code
