OpenNMS Meridian vs. SolarWinds Database Performance Monitor

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.

Computing resources consumed by the DB instance, DPA queries & wait time, deadlock conditions, virtual infrastructure resources. The addition of NPM & DPA integration as well as cross-correlation in the identification of issues with the network or server or DB is all stupid-proof. Monitoring is more than just health and resource consumption, it's also performance. DB performance analysis is key to maintaining healthy DB instances.

• 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.

I would say it is a very good tool from overall perspective compared to what I have used till now, still I will give it like 9 just for the sake of the interface and the integration which they should be doing soon with the main module which is SAM , NPM etc.

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.

SolarWinds DPA gives you a very deep analysis and monitoring of the devices which these tools will not give you neither Datadog or ManageEngine. It even gives you job rate , db locks and all other parameters to monitor which we usually do manually by going in to the DB and not from the tools. It also creates a dashboard out of the same.

• 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.
