Sysstat is a collection of Unix tools used for performance monitoring, the package includes tools such as iostat , mpstat , pidstat , sadf and sar . Along with the real time commands sysstat will install a cronjob that will run every 10 minutes and collect the systems performance information.

Report Sar Data Using Start Time (sar -s) When you view historic sar data from the /var/log/sa/saXX file using “sar -f” option, it displays all the sar data for that specific day starting from 12:00 a.m for that day. Using “-s hh:mi:ss” option, you can specify the start time.

Introduction. The sysstat package contains various utilities, common to many commercial Unixes, to monitor system performance and usage activity: iostat reports CPU statistics and input/output statistics for block devices and partitions. mpstat reports individual or combined processor related statistics.

The old good top command to find out Linux CPU Utilization

1. Top command to find out Linux cpu usage.
2. Say hello to htop.
3. Display the utilization of each CPU individually using mpstat.
4. Report CPU utilization using the sar command.
5. Task: Find out who is monopolizing or eating the CPUs.
6. iostat command.
7. vmstat command.

How to Set Up Automatic Data Collection

1. Become the root role.
2. Run the svcadm enable system/sar:default command.
3. Edit the /var/spool/cron/crontabs/sys crontab file.
4. Uncomment the following lines: 0 * * * 0-6 /usr/lib/sa/sa1 20,40 8-17 * * 1-5 /usr/lib/sa/sa1 5 18 * * 1-5 /usr/lib/sa/sa2 -s 8:00 -e 18:01 -i 1200 -A.

As the Sysstat is a command-line-based system monitoring tool, it provides real-time system info. Furthermore, you can also troubleshoot your system through the Sysstat tool.

If you’re a Ubuntu or other Debian-based Linux user, you can install the Sysstat tool on your system through the official Linux repository. Run the following aptitude command on your terminal shell with root privilege to install it on your system. 2. Install Sysstat On Fedora And Red Hat Linux

Installing the system statistics tool on an Arch-based Linux system is similar to installing it on other Linux systems. You can install the Sysstat tool on your Arch Linux system through the Pacman command. For example, run the following Pacman command given below on your shell to install the system statistics tool.

After compilation process completes, you will see the output similar to above. Now, verify the sysstat version by running following command. By default sysstat use “ /usr/local ” as its prefix directory. So, all binary/utilities will get installed in “ /usr/local/bin ” directory.
