![]() This will not calculate the swap memory in results. cd /usr/lib/nagios/plugins/Įdit NRPE configuration file and add a command to check memory uses like below. On CentOS/RHEL 64-bit systems this local will be /usr/lib64/nagios/plugins. Download check_mem.pl using the following command and copy it to the Nagios plugins directory. e.g., Ubuntu and CentOS, where the command doesnt work (always indicates 100, because parsing fails due to the. To get the current value top (or similar tool) must be used. This could be very different from the current CPU usage. You can download the check_mem.pl and configure with NRPE daemon. NOTE: this is not the current CPU usage, but the overall CPU usage in all the cores since the system bootup. And obviously your script now wants you to talk (via keyboard) to the remote server. At regular intervals, it shows system-level activity related to the CPU, memory, swap, disks, and network layers, and for every active process it shows the CPU utilization, the memory growth, priority, username, state, and exit code. Monitor Memory UsesĪ Nagios plugin is available to monitor memory uses on Linux systems. Another thing that could be causing the high CPU load is a cron job or any other scheduled task. After the SSH command, you are on the remote server, in an SSH shell. The requests go to the remote host and the NRPE server checks for the command defined as check_load and execute it. ![]() regular Ubuntu and Ubuntu Server Reply AmSoDoneWithThisShit. sysstat will collect background CPU usage data every minute, saving it to /var/log/sysstat/. Ubuntu 20.04 LTS: RAM: 780 MiB, CPU: 9, Storage space used: 7.6 GB Kubuntu: RAM: 0.47 GiB, CPU: 4, Storage space used: 7 GB. You can generate a real-time report with the following command: sar -u 1 3. docker stats awesomebrattain 67b2525d8ad1 CONTAINER ID NAME CPU MEM. Let’s verify the configuration by running the check_nrpe command from the Nagios serverĪs per the above screenshot, the Nagios server sent NRPE requests to the defined host (192.168.1.15) to execute command check_load and send results back. Edit: Might actually check my ram usage later and update this. On Linux, the Docker CLI reports memory usage by subtracting cache usage from the. Command =/ usr/ lib/ nagios/ plugins/ check_load - w 15, 10, 5 - c 30, 25, 20
