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
iostaton the system to be monitored and see what name has been assigned to the disk you desire. The default value of
0usually provides statistics from the first hard drive connected directly to the system.
Requirements — The Red Hat Network Monitoring Daemon (
rhnmd) must be running on the monitored system to execute this probe. Also, the Disk number or disk name parameter must match the format visible when the
iostatcommand is run. If the format is not identical, the configured probe enters an UNKNOWN state.
