How would I configure ntperf to monitor IOPS?
Release : 20.3+
Component : UIM - NTPERF
Please create a new profile, and then choose PhysicalDisk under the Object. There are counters such as
Disk sec/Transfer – the time required to perform one write/read operation with the storage device or disk (disk latency). If the delay is more than 25 ms (0.25), then the disk array cannot handle the I/O operation on time. For high load servers, the disk latency value should not exceed 10 ms (0.1)
Disk Transfers/sec – (IOPS). The number of read/write operations per second. This is the main indicator of the disk access intensity.
Disk Bytes/Sec – Total disk throughput (read+write) per second. Maximum values depend on the disk type (150-250 Mb/s – for a regular HDD disk and 500-10000 for SSD)
Split IO/sec – a disk fragmentation indicator when the operating system has to split one I/O operation into multiple disk requests. It may also indicate that the application is requesting too large blocks of data that cannot be transferred in one operation.
Based on your need you can monitor one or several of them:
