OpenNMS Meridian vs. vRealize Operations (discontinued)

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.

With the introduction of API-based event alerts, there is no need for a proxy, which is a good option. Its ability to manage infra on a real-time basis is a good option that helps monitor, administer and troubleshoot virtual machines.

• 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 has a good GUI to monitor real-time logs for cloud applications. This is quite a useful tool and preferred over most of the competitive applications in the market.

The support is pretty good however some of the KB articles still reference different versions of the product so it can be hard to find answers to common questions

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.

SCOM was quite overwhelming when we first set up a POC for it. There was just too much for one person to handle. With vROPs I can manage the product and provide the support needed for my environment. We also have a Solarwinds environment that provides us with a level of detail and alerting we have come to rely upon. vROPS takes it to another level because it links directly into vCenter to provide you with a complete picture of your virtual environment.

• 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.

• We believe that the ability to preplan deployments with vRealize has proven its return on investments.
• Our troubleshooting time has been reduced with vrealize because its constantly collecting performance data. typically vrealize will tell us cause of fault before we can determine it ourselves.
