Linux Disk PerformanceLast updated on 17 March, 2023
In order to get detailed performance monitoring of physical disk drives, LogicMonitor requires a specific configuration in the net-snmp snmpd agent.
Add this line:
extend diskstats /bin/cat /proc/diskstats
to snmpd.conf, and restart the snmpd daemon.
The Disk Performance datasource will then discover all physical drives and monitor their performance. (You can manually trigger ActiveDiscovery to speed up that process.)
Note: only physical block devices (sda, sdb, etc) are monitored, not partitions (sda1, sdb3, etc). Some systems have partitions, but not block devices – if you need support for such systems, please contact LogicMonitor support.
