This is part two of our blogs about which counters you use when monitoring your servers. Click here for part one, about memory counters.
Disk space available
The amount of disk space available, in GB, per logical disk.
Logical disk idle time
The percentage of elapsed time that the disk is not servicing any read or write requests
Logical disk average read latency
Average time, in seconds, of a read of data to the disk.
Logical disk average write latency
Average time, in seconds, of a write of data to the disk.
Logical disk transfer/sec
The rate of read and write operations on a disk.
Note: all these counters are for logical disks only. We are not currently proposing to capture any metrics for the physical disk drive. Is this something you’d need to see?
Are these counters useful to you? Are there are any other disk counters that you look at, that we’ve not mentioned here? Let us know!
