[root@localhost ~]# yum -y update Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.piconets.webwerks.in * epel: mirrors.piconets.webwerks.in * extras: mirrors.piconets.webwerks.in * updates: mirrors.piconets.webwerks.in Resolving Dependencies --> Running transaction check ---> Package NetworkManager.x86_64 1:1.18.0-5.el7_7.1 will be updated ---> Package NetworkManager.x86_64 1:1.18.0-5.el7_7.2 will be an update ---> Package NetworkManager-libnm.x86_64 1:1.18.0-5.el7_7.1 will be updated ---> Package NetworkManager-libnm.x86_64 1:1.18.0-5.el7_7.2 will be an update ---> Package NetworkManager-team.x86_64 1:1.18.0-5.el7_7.1 will be updated ---> Package NetworkManager-team.x86_64 1:1.18.0-5.el7_7.2 will be an update ---> Package NetworkManager-tui.x86_64 1:1.18.0-5.el7_7.1 will be updated ---> Package NetworkManager-tui.x86_64 1:1.18.0-5.el7_7.2 will be an update ---> Package binutils.x86_64 0:2.27-41.base.el7_7.1 will be updated ---> Package binutils.x86_64 0:2.27-41.base.el7_7.3 will be an update ---> Package curl.x86_64 0:7.29.0-54.el7_7.1 install psacct will be updated ---> Package curl.x86_64 0:7.29.0-54.el7_7.2 will be an update ---> Package docker.x86_64 2:1.13.1-103.git7f2769b.el7.centos will be updated ---> Package docker.x86_64 2:1.13.1-109.gitcccb291.el7.centos will be an update ---> Package docker-client.x86_64 2:1.13.1-103.git7f2769b.el7.centos will be updated ---> Package docker-client.x86_64 2:1.13.1-109.gitcccb291.el7.centos will be an update ---> Package docker-common.x86_64 2:1.13.1-103.git7f2769b.el7.centos will be updated ---> Package docker-common.x86_64 2:1.13.1-109.gitcccb291.el7.centos will be an update ---> Package epel-release.noarch 0:7-11 will be updated
Step 3: Install psacct tool
Next step is to install psacct user monitoring tool by using yum install -y psacct
command as shown below.
[root@localhost ~]# yum install -y psacct Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile epel/x86_64/metalink | 7.4 kB 00:00:00 * base: mirrors.piconets.webwerks.in * epel: mirrors.piconets.webwerks.in * extras: mirrors.piconets.webwerks.in * updates: mirrors.piconets.webwerks.in base | 3.6 kB 00:00:00 download.mono-project.com_repo_centos_ | 2.9 kB 00:00:00 epel | 4.7 kB 00:00:00 extras | 2.9 kB 00:00:00 kubernetes/signature | 454 B 00:00:00 kubernetes/signature | 1.4 kB 00:00:00 !!! nodesource | 2.5 kB 00:00:00 puppetlabs-pc1 | 2.5 kB 00:00:00 updates | 2.9 kB 00:00:00 (1/2): epel/x86_64/updateinfo | 1.0 MB 00:00:01 (2/2): epel/x86_64/primary_db | 6.8 MB 00:00:04 Resolving Dependencies --> Running transaction check ---> Package psacct.x86_64 0:6.6.1-13.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ======================================================================================================================================================================== Package Arch Version Repository Size ======================================================================================================================================================================== Installing: psacct x86_64 6.6.1-13.el7 base 93 k Transaction Summary ======================================================================================================================================================================== Install 1 Package Total download size: 93 k Installed size: 199 k Downloading packages: psacct-6.6.1-13.el7.x86_64.rpm | 93 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : psacct-6.6.1-13.el7.x86_64 1/1 Verifying : psacct-6.6.1-13.el7.x86_64 1/1 Installed: psacct.x86_64 0:6.6.1-13.el7 Complete!
Step 4: Check and Start psacct Service
If you check psacct service immediately after installation using service psacct status
command then it will show in inactive
state as you can see below.
[root@localhost ~]# service psacct status Redirecting to /bin/systemctl status psacct.service ● psacct.service - Kernel process accounting Loaded: loaded (/usr/lib/systemd/system/psacct.service; disabled; vendor preset: disabled) Active: inactive (dead)
You need to start the service by using service psacct start
command.
[root@localhost ~]# service psacct start Redirecting to /bin/systemctl start psacct.service
Now if you again the psacct service status using service psacct status
command then it will show in active and running state as shown below.
[root@localhost ~]# service psacct status Redirecting to /bin/systemctl status psacct.service ● psacct.service - Kernel process accounting Loaded: loaded (/usr/lib/systemd/system/psacct.service; disabled; vendor preset: disabled) Active: active (exited) since Sun 2020-04-05 09:21:10 EST; 5s ago Process: 24115 ExecStart=/usr/sbin/accton /var/account/pacct (code=exited, status=0/SUCCESS) Process: 24112 ExecStartPre=/usr/libexec/psacct/accton-create (code=exited, status=0/SUCCESS) Main PID: 24115 (code=exited, status=0/SUCCESS) CGroup: /system.slice/psacct.service Apr 05 09:21:10 localhost systemd[1]: Starting Kernel process accounting... Apr 05 09:21:10 localhost accton[24115]: Turning on process accounting, file set to '/var/account/pacct'. Apr 05 09:21:10 localhost systemd[1]: Started Kernel process accounting.
Step 5: Verify the Package Installation
If you want to verify the psacct package installation in RPM DB then you need to use rpm -qa | grep -i psacct
command as shown below.
[root@localhost ~]# rpm -qa | grep -i psacct psacct-6.6.1-13.el7.x86_64
Step 6: Enable psacct service
If you want psacct service to be enabled on Run Level 1 and 3 then you need to use chkconfig --level 13 psacct on
command as shown below. You can also use systemctl enable psacct
command to enable the service at the boot time.
[root@localhost ~]# chkconfig --level 13 psacct on Note: Forwarding request to 'systemctl enable psacct.service'. Created symlink from /etc/systemd/system/multi-user.target.wants/psacct.service to /usr/lib/systemd/system/psacct.service.
Step 7: Check ac and sa version
If you want to check the ac command version then you need to use ac -V
command as shown below. As you can see from below output current ac command version is 6.6.1
[root@localhost ~]# ac -V ac: GNU Accounting Utilities (release 6.6.1)
If you want to check the sa command version then you need to use sa -V
command as shown below. As you can see from below output current sa command version is 6.6.1
.
[root@localhost ~]# sa -V sa: GNU Accounting Utilities (release 6.6.1)
Step 8: Using ac User monitoring tools
If you want to print the total hours for each user then you need to use ac -p
command as shown below.
[root@localhost ~]# ac -p root 3460.19 total 3460.19
p : Print time totals for each user in addition to the usual everything-lumped-into-one value. More on ac command Man Page.
Step 9: Check Package details of ac and sa utility
If you want to check the package details of ac utility then you need to first find the complete path of ac utility using which ac
command as shown below.
[root@localhost ~]# which ac /usr/bin/ac
Then you need to query the RPMDB for package details using rpm -qf /usr/bin/ac
command.
[root@localhost ~]# rpm -qf /usr/bin/ac psacct-6.6.1-13.el7.x86_64
Similarly, for sa utility also you need to first query the command path using which sa
command.
[root@localhost ~]# which sa /usr/sbin/sa
Then you need to query the RPMDB using rpm -qf /usr/sbin/sa
command to know about the package details.
[root@localhost ~]# rpm -qf /usr/sbin/sa psacct-6.6.1-13.el7.x86_64
Step 10: Remove psacct package from Server
If you want to remove psacct package from your Server then you need to use yum remove psacct -y
command as shown below.
[root@localhost ~]# yum remove psacct -y Loaded plugins: fastestmirror Resolving Dependencies --> Running transaction check ---> Package psacct.x86_64 0:6.6.1-13.el7 will be erased --> Finished Dependency Resolution Dependencies Resolved ======================================================================================================================================================================== Package Arch Version Repository Size ======================================================================================================================================================================== Removing: psacct x86_64 6.6.1-13.el7 @base 199 k Transaction Summary ======================================================================================================================================================================== Remove 1 Package Installed size: 199 k Downloading packages: Running transaction check Running transaction test Transaction test succeeded Running transaction Erasing : psacct-6.6.1-13.el7.x86_64 1/1 Verifying : psacct-6.6.1-13.el7.x86_64 1/1 Removed: psacct.x86_64 0:6.6.1-13.el7 Complete!
