Observium vs. OpenNMS Meridian

• If you are on a budget, this is one heck of a tool for the price (including the ~$200/year for the Pro subscription).
• If you are OK with maintaining and updating open source tools, this is a great tool.
• If you are afraid of the Linux command line or live in a Windows-centric world, this might not be the tool for you.
• If you can't stand things occasionally not working, this is probably not a good fit.

I would recommend all system administrators use some form of network monitoring if they are not already doing so, and I'd definitely recommend people consider OpenNMS if they're shopping around. Small businesses will benefit from the low-cost of entry (it's free!), whilst getting all the enterprise features. Larger businesses can benefit from paid support plans.

However, there's no getting around the fact that you will require some advanced networking and sysadmin knowledge to get the most out of OpenNMS, or at least, be prepared for a steep learning curve. If you don't have the resources to devote this time initially, you may struggle.

• We've had a few issues with delayed alerting.
• I haven't quite figured out how to make topologies work yet, but I haven't spent a ton of time on it either.
• We've also had a bit of trouble importing some MIBs, but that usually boiled down to working with the vendor to make sure we had the right MIBs and dependencies.

It's open source. Your mileage may vary. Sometimes the provided documentation is beyond frustrating, other times it's right on the mark.

I haven't used other products that are similar to Observium. Observium is an open tool, with a robust feature set. There are elements of comparable monitoring across other tools, but nothing I've seen that is a complete parallel in terms of feature set and visualizations. If I were asked, I wouldn't have another tool to recommend over Observium.

OpenNMS's more attractive GUI and its price break were the main reasons our company chose to explore and use this product. However, it never managed to actually replace Nagios which had a much more established hold within the company. Perhaps we were over-monitoring, but our company claimed a $100k loss per hour of downtime.

• It is good for DC admin.
• Only positive impact.
• Highly recommended.

• Initial adoption required quite a lot of resources and time to get everything right. Totally worth it for us; just be prepared for a gradual process that will get better and better with time.
• Once setup and running smoothly, it provides us with all the reporting we could hope for, at near zero cost.
• With OpenNMS, we're able to offer a much more reliable service to our customers, and spend a lot less time dealing with issues.
