OpenNMS Meridian vs. Pandora FMS

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.

I believe Pandora FMS is a solution that adapts to any type of scenario; it's useful for small businesses as well as large organizations. It more than meets the need to have a comprehensive monitoring system capable of sending alerts instantly and consulting historical data, logs, and trends. Additionally, for small businesses, the free version will be more than sufficient in most cases. And for those who do not want to deploy the service on-premise, there is an option for MaaS (Monitoring as a Service).

• 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.

• The interface is not intuitive due to the number of options it has and its organization.
• It has a free version with limitations, and another paid version. The commercial one has a quite high cost.
• It has a certain learning curve.

The support team answers very quickly. They are always willing to find a solution to any need that is required by us or one of our clients.

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.

We considered Pandora FMS to be the solution that offered more features at a lower cost. We were particularly interested in the abundance of options available in Pandora FMS's free version and the ability to monitor practically anything in an extremely heterogeneous environment like ours. We also considered Pandora FMS for its management capabilities and the possibilities offered by its web interface.

• 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.

Incentivized

• It is a tool with an appropriate cost that allows to have results in a very limited time.
• Having a health dashboard and alerts of important business in the company is an important differential with any other monitoring solution on the market.
• Monitoring can be adjusted to the business, considering service SLAs and adjusting the platform according to the needs of each department of the company.
