Blk_wrtn/s – Total amount of data written in blocks per second. Blk_read/s – Total amount of data read in blocks per second. It shows the current data transfer per second, the total number of blocks read and write to disk and an average block per seconds.iostat -d 1 5 Details: tps – Transfers per second. To view utilization details of each core individually use -P ALL command.sar -P ALL 1 3 View Device Usage – Use the iostat command to find disk statics. Nowadays most of the CPU’s are multi-core. For example, to view real-time CPU uses for 5 times with the difference of 1 second.sar -u 1 5 You can view the CPU utilization data in more depth. Below is some about various static to view on command line.Ĭurrent CPU Usage – Use -u with the sar command to view realtime cpu staticssar -u You can also view the real-time CPU uses by specifying the time interval and number of times to show data. You can get real time system static with sar command line tool. Edit the following file and save it.Īfter enabling the monitoring, enable the sysstat service and start it by executing: Step 3 – Realtime Monitoring with Sysstat # You need to Let’s enable the sysstat monitoring. To enable the sysstat monitoring, edit the configuration file in text editor: Step 2 – Configure Sysstat #īy default Sysstat monitoring is disabled. If you still want to use package manager just run below commands.

So we recommend to use installation with source in next step. But the default repositories have older version of packages. Sysstat package is available in default package repositories, You can install using the following commands. sar – Used for collects and saves all the system activities and report. cifsiostat – Used for generating reports CIFS statistics. tapestat – Used for the statistics for tape drives attached to Linux system. pidstat – Used for I/O, CPU, memory statistics for Linux processes and generate report. mpstat – Used for processor related statistics and reports.

Iostat – Used for CPU statistics and input/output statistics for the block devices and partitions and generate report. The sysstat package provides a number of utilities for collecting the system use activities and system performance.
