That is, the amount of time in a second for I/O operations, or how much time in a second I/O queue is non-empty, calculation method: (r/s+w/s) * (svctm/1000) %util indicates how busy the disk is. 100% indicates that the disk is busy and 0

Disk IO performance monitoring (Linux and Windows)End South [email protected]>The IO performance of a disk is an important indicator of the overall performance of a computer. Linux provides the Iostat command to obtain the disk in

Zabbix's "template OS Linux" Templates support monitoring mounted disk space utilization, which is implemented using LLD (low-level discovery) without disk IO monitoring. This article describes the method of monitoring

The IO performance of a disk is an important indicator of the overall performance of the computer. Linux provides the IOSTAT command to obtain disk input/output (i.e. IO) statistics, and Windows provides a WMI interface that allows you to write a simple script to get the functionality that is equivalent to Iostat. 1,
