Entuity vs. OpenNMS Meridian

I think that if your organization is network-oriented (such as telecom or ISP) deploying Entuity should be considered a mandatory step. Big organizations will benefit from the ITSM (ticketing, monitoring and CMDB) integrations.

However, if your goal is to ensure that the server layer is monitored in great level (process and service monitoring, log parsing etc.) then Entuity will not suit your needs.

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.

Entuity support has always been quick to respond and the majority of the calls I had were resolved on the first call. In addition, the product documentation is easy to read and goes into great detail of how the product works. This is probably a reason why a support call is literally the last call for Entuity (no pun intended).

The list above shows you some of the products that Entuity replaces.

The good product and excellent support behind it make it a better choice from the admin's and EA's perspective. My customers have praised the short learning curve and the swift and professional support staff. From my own experience I can tell that this product is delivered with one of the finest sets of documentation I have ever seen.

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.

• Reconciling multiple tools (netflow, configuration, monitoring and discovery) into one tool simplified the support agreement.
• Root cause analysis (RCA) time has been greatly reduced thanks to having all information in a single interface.
• Security of the network devices has improved thanks to the discovery provided by Entuity.

• 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.
