Linux Disk Performance

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 DataSource “Linux Disk Performance-” 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.
