Hi all, I've looked at the documentation, at the mailling lists, and googled around, and don't explicitly see it so thought i'd try here.... On our system, I've set up nagios and it's monitoring a few things (http, etc) just fine. However, one of our applications is giving us grief and sometimes starts consuming >80% of a cpu (it's a quad-core machine). So i'd like to set up a monitor to see how often this happens and to get notified. Looking around, it seems like 'check_procs' with the CPU metric should do what i want. However, it doesn't seem to behave quite as I'd expect. If I look at 'top' on this linux system, for our 'problem' application, i see this (and it will be constant like this for > 1 hour): PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 20022 ourapp 18 0 1428m 1.0g 13m S 104 25.7 442:18.39 java So when I run this command, I'd expect to see 1 process flagged: [root@ours libexec]# ./check_procs -w 10 -c 20 --metric=CPU CPU OK: 173 processes I've tried adding the '-u' flag but made no difference. Is there something I'm missing if I want to capture and be notified when a process goes above a certain CPU usuage (ie. 80%)? Any help or information you could provide would be appreciated. Thanks
