I previously used Nagios and because of the painful configurations, I found OpenNMS. It does all I need and more, being more easier than Nagios. It uses PostgreSQL and runs on top of Tomcat4.
Here is how I installed OpenNMS and it's prereqs. It's rough, but it works.

A bit off topic, but I keep looking for an answer to this question and coming up with nothing... so I thought I would go to the gurus. :-)
Can anyone recommend a good package for pinging other devices and sending an email/alert when they go down? I'm aware of all kinds of more complex things with GUIs and a zillion other bells and whistles we aren't looking for, but we just want a simple tool (could be daemon or something run from cron) that runs every 1 - 5 minutes and alerts us when stuff disappears. Would need some basic logic like only sending one email/alert when something goes down (vs sending an email every 1-5 minutes until it comes back up). :-) We need to avoid a requirement for an X-windows GUI, but a web-GUI would probably be fine (a GUI-less command-line thing would probably be best).
This probably isn't the best anymore, but I've had it running with no particular problems for 5 or 6 years - before any of the others like it were available. It is all-perl, has one server process to collate the responses and rate-limit the alarms, one network probe for all the remotely checks, and optional local clients for some things that can only be tested locally. It is fairly easy to add custom tests for local applications. http://spong.sourceforge.net/

Do any of these alternatives combine the ability to monitor current status with a grid-like display of many systems and services with notification alarms and also keep long-term historical graphs of values? I'm currently running spong for notifications/status and cacti for history/graphs, but I'd like to find something that does both with one snmp query.
Hi everyone,
Great thread. Thanks to all for their input!
Bryan asks a good question about whether we are looking for a full SNMP tool. Actually, we have some pretty big systems that already handle those functions. For this project, we are just looking for ping-type "is it up or down" information on a "subset of the overall network."
It looks like Jacob's recommendation for Mon could be spot on. But, that being said, OpenNMS and Zabbix look pretty cool and worth a look (possibly for other projects with more complex needs). Re a script, I was going to do something like that if I couldn't get anything here :-) but I was trying to avoid having to add in the "don't send and email every time it checks during a prolonged outage" (just send at the beginning and maybe the end).
Let me know if folks think of other ideas.
Thanks again, Kennedy

Hi all,
I haven't seen anybody mentioning Argus: website: http://www.tcp4me.com online demo: http://www.tcp4me.com/cgi-bin/argus?func=login&name=manager&passwd=x...
It does exacly what was asked in the thread starter post (ping and alert with rate limits) and even more if needed (monitor services, or even webpages :) ). I use it for over a year now, and am very happy with it.
Hope it helps, Alex
