Check Processes and Ports

Project Notes

Heavily based on check_linux_procs. A script that checks if processes and TCP ports are up. Tested on Redhat Enterprise Linux 3/4, Fedora 4, Solaris 6,7,8,9 and HP-UX 11.11, 11.23 Process checks are divided into two different levels, warning and critical. This way you may monitor less important processes and critical processes at the same time. The part that checks if ports are up uses netstat. It will mostly detect if an server application does not start up correctly, and thereby does not open up it's port. If you want to be sure ports are up and that the application is listening on it, use more specialized socket check scripts or check_tcp. Usage: Edit the check_system_pp script and add whatever processes and ports that you want to monitor. For example: ---snipp---- PROCLIST_RED="sshd crond klogd" PROCLIST_YELLOW="less_critical_process other_stuffd" PORTLIST="22 25" ---snipp---- Command line example for nrpe.cfg: commandcheck_system=/path/to/nrpe/libexec/check_system_pp FAQ: Q: I do not have Bash installed. What to do? A: Just use regular bourne shell (sh). Edit the first line in the script to the path of sh. For example: #!/usr/bin/sh
