Re: OT: Nagios/ OpenNMS

Totally agreed - we have 1500 line bash scripts running that call 20 system level commands to a list in a seperate file of 30+ machines at an exchange and save them to a log or mysql database - sending an email if certain conditions are met... With linux its like the bee gee's -

"How deep is your love"

It comes down to is your time doing something else worth more or less than the cost of doing nagios at a very high level.

Like how can nagios (or any nms) start up a tshark or tcpdump for exactly 60 seconds, count the number of multicast messages sent to a group, and if that number is too low or high, send an email to the team - that's one of a hundred things we have to monitor - so all this becomes an art. I do like the fact nagios has an agent - no nms can really do everything just polling mibs.

Nagios has many add ons that can enhance feature set. I used MRTG for bandwidth statistics and threshold alerting. Nagios is very flexible for alerting via email, SMS, and IM. Virtually any MIB that can be walked can be trapped and alerts sent. It takes intermediate knowledge of Linux... Including every disto can be a little different. But I would argue that Nagios can do virtually anything a paid NMS can do minus IP SLA recording/reporting.. That may have changed as well.

Exactly good points Marc - we use logicmonitor.com<http://logicmonitor.com>, opmanager & smokeping. The only open source one we invest lots of time in is smokeping for real-time alerts and some very custom high frequency bash scripts that track and alert ntp and ptp clock and timing issues.

thanks

We use both to some extent. I find nagios great for setting alerts but not really a full NMS. OpenNMS is ok. It can monitor and provide graphs but unless you spend a long time building custom views it is hard to use it from a network perspective. Our systems guys like it because they can easily drill down on one host. From a network perspective though I couldn't find any good views to give me stats on the various uplinks etc. Basically if I was hunting an issue I would have to go look link by link.

I have purchased Solar Winds and it is much more useful from a network perspective.
