ManageEngine NetFlow Analyzer vs. OpenNMS Meridian

Identifying network traffic anomalies. Identifying applications, devices, or users that are utilizing high bandwidth. Capacity planning for network links and internet circuits. Detecting potential security threats or breaches. Network performance and troubleshooting. Reporting network utilization.

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.

Easy to implement, it does not require much hardware for installation, it is very accurate in the process of discovering and analyzing network packets and traffic consumption, as well as its graphs and best practices to implement. On the other hand, we can keep track of network devices and identify security vulnerabilities.

The support is always on point, fast, reliable, and their employees go above and beyond to help when we need it. I have yet to call them on any product we use and not get the issue resolved in a fast and timely manner. Also, they are also very pleasant while on the phone and/or in teh email chain. Overall I just couldn't ask for better.

Each of these solutions does what they aim to do. Based off of cost and need, ManageEngine fit better with our organization. We already use multiple ManageEngine products so bundling was a no brainer.

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.

Incentivized

• Lot of positive impacts
• Low Budget
• Great results

• 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.
