Step 1: Prerequisites

a) You need to have a running RHEL/CentOS 7/8 System.

b) You should have yum tool installed in your Server. You can check Top 22 YUM command examples in RedHat/CentOS 7 to know more about yum command.

c) You need to have root or sudo access to run privileged commands. Please Check How to Add User to Sudoers to know more about providing sudo access to the User.

Step 2: Update Your Server

Before going through the steps to install iostat and mpstat command on Linux Server it is always recommended to update your Server first with latest available release by using yum update -y command as shown below. This step is especially more important for those servers which were not updated from quite sometime.

Step 3: Install Sysstat Package

Sysstat package can be installed by using yum install sysstat -y command as shown below. This will install iostat and mpstat tool in your server.

[root@localhost ~]# yum install sysstat -y
Loaded plugins: fastestmirror
* base: centos.hbcse.tifr.res.in
* epel: epel.mirror.angkasa.id

Step 4: Verify Package Installation

Once the package is installed you can verify the source package of the command mpstat and iostat by querying the RPM DB using rpm -qf <tool_path> command. Please Check 25 Practical and Useful rpm command examples in Linux{cheatsheet} to know more about rpm command.

[root@localhost ~]# rpm -qf /usr/bin/mpstat
sysstat-10.1.5-19.el7.x86_64
[root@localhost ~]# rpm -qf /usr/bin/iostat
sysstat-10.1.5-19.el7.x86_64

Step 5: Check iostat and mpstat version

If you check the current installed version iostat and mpstat command using -Version option then you will see current installed version is 10.1.5 for both of them.

[root@localhost ~]# iostat -Version
sysstat version 10.1.5
(C) Sebastien Godard (sysstat <at> orange.fr)
[root@localhost ~]# mpstat -Version
sysstat version 10.1.5
(C) Sebastien Godard (sysstat <at> orange.fr)

Step 6: Checking I/O Performance Using iostat

To check Linux Server I/O performance you can simply run iostat command as shown below. Here you can get important information like amount of data read from the device, amount of data written to the device, number of read requests, number of write requests and so on. Check more on iostat Man Page.

[root@localhost ~]# iostat
Linux 3.10.0-1160.2.2.el7.x86_64 (localhost.localdomain) 12/06/2020 _x86_64_ (1 CPU)

avg-cpu: %user %nice %system %iowait %steal %idle
0.41 0.01 0.27 0.10 0.00 99.21

Device: tps  kB_read/s kB_wrtn/s kB_read kB_wrtn
sda     7.34 114.72    16.63     373234  54111
sdb     0.04 0.83      0.00      2688      0
sdc     0.05 1.62      0.00      5284      0
dm-0    7.21 104.59    16.00     340287  52043
dm-1    0.03 0.68      0.00      2204      0

Step 7: Checking Processor Stats Using mpstat

To check the Linux Server Processor stats you can simply run mpstat command as shown below. By default it will show information about all the CPUs. Using this tool you can check processor information like cpu utilization at user level, cpu utilization at system level, cpu utilization at user level with nice priority, time spent by cpu to service hardware interrupts and so on. Check more on mpstat Man Page.

[root@localhost ~]# mpstat
Linux 3.10.0-1160.2.2.el7.x86_64 (localhost.localdomain) 12/06/2020 _x86_64_ (1 CPU)

03:34:29 AM CPU %usr %nice %sys %iowait %irq %soft %steal %guest %gnice %idle
03:34:29 AM all 0.41 0.01  0.26  0.10   0.00 0.01  0.00   0.00   0.00   99.21
