C.5.2. Linux::Disk IO Throughput
The Linux::Disk IO Throughput probe monitors a given disk and collects the following metric:
Read Rate — The amount of data that is read in kilobytes per second.
Write Rate The amount of data that is written in kilobytes per second.
To obtain the value for the required Disk number or disk name field, run iostat on the system to
be monitored and see what name has been assigned to the disk you desire. The default value of 0 will
usually give you statistics from the first hard drive connected directly to the system.
Requirements The Red Hat Network Monitoring Daemon (rhnmd) must be running on the moni-
tored system to execute this probe.
