OpenNMS comparison
Thank you, Vincent. We are big Nagios fans but eventually chose OpenNMS for our primary monitoring system but it was truly neck and neck with great admiration for both. I'd be curious to hear how others have fared who have evaluated both.
We were as much concerned with trending and autoremediation as monitoring. We also wanted to standardize on SNMP rather than introduce NRPE. All of that can be done with Nagios and, believe it or not, the Nagios configuration is much easier and more flexible. However, OpenNMS seemed to edge it out on SNMP support, auto-discovery (for better or worse!), scaling to very large infrastructures, and lower network overhead (though much higher management server overhead). But, as I said, OpenNMS edged out Nagios by just a nose. Where have others come out in similar real world comparisons? - John
