Once you combine this knowledge with the output of iostat, you can make changes to your system accordingly. The practical application is this: if you know what hardware is used, then you know what parameters it should be operating within. Also, note that the tps field is the total number of Transfers per second issued to a specific device. The output includes totals, as well as per second values for both read and write operations.

It also displays I/O stats for each partition on the system. If you run the base command without options, iostat displays CPU usage information. Sysstat-11.7.86_64 Collection of performance monitoring tools for Linux Lm_sensors-libs-3.4.86_64 Lm_sensors core libraries The following packages have to be installed: Install package 'sysstat' to provide command 'iostat'? y NOTE: the command runs automatically after installation.

I am using Red Hat Enterprise Linux 8 here and have included the install output below. iostat is a part of the sysstat package and is not loaded on all distributions by default. For input/output monitoring, we use the iostat command. We know that Linux is loaded full of helpful tools for all manner of issues. I have seen a single replication job take months. If all is well, we are talking hours, if not. However, the throughput of a system can have huge implications for massive data transfers. Now, if you have ever worked in support, you know that there can be many causes for a symptom. Many times, customers would contact me concerned about the speed of the data transfer from production to storage. One of my many tasks in that role was to help customers replicate backups from their production environments to dedicated backup storage arrays. If you have followed my posts here at Enable Sysadmin, you know that I previously worked as a storage support engineer. How well do you know Linux?
