A.5.2. Linux::Disk IO Throughput
The Linux::Disk IO Throughput probe monitors a given disk and collects the following metric:
Read Rate - T he 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 num ber or disk nam e field, run iostat on the system to
be monitored and see what name has been assigned to the disk you desire. T he default value of 0
usually provides statistics from the first hard drive connected directly to the system.
Requirements - T he Red Hat Network monitoring daemon (rhnm d) must be running on the monitored
system to execute this probe. Also, the Disk num ber or disk nam e parameter must match the
format visible when the iostat command is run. If the format is not identical, the configured probe
enters an UNKNOWN state.
