OpenNMS

We've been using OpenNMS for network monitoring and have been fairly happy with it. There can be a bit of a learning curve to the setup and installation which might turn some people off, but if you can work through the learning curve it's a pretty powerful tool at the awesome price of free (paid support is available).

Zenoss

Perfect for multi-vendor infrastructure monitoring. Excellent end-to-end troubleshooting, due to real-time dependency mapping.The new Cloud platform is perfect for widely distributed companies, and those looking to minimize administration requirements for the monitoring platform. The prem-based Zenoss platform would be a better fit for organizations not willing to use a cloud-based monitoring application. Zenoss isn't currently a true app performance monitoring platform, so it would need to be used in conjunction with something like AppDynamics.

Pros

OpenNMS

  • When we used OpenNMS you could download the base package for free and configure it fairly easily for your own environment. You can't beat that kind of price break.
  • OpenNMS had a very nice looking GUI that was easily navigated and fairly straightforward to understand and configure.
  • There were a wide variety of add-ons available for download and implementation.

Zenoss

  • Multi-platform support across a wide range of hardware and software infrastructure. Truly a vendor-agnostic platform.
  • Vendor-specific feature/configuration support, via ZenPacks, providing much better end-to-end visibility as compared to most legacy monitoring platforms -- especially for devices such as firewalls, middleware gateways, and load balancers.
  • Modern, cloud-native software architecture, as compared to legacy monitoring platforms. As a result, Zenoss Cloud should prove to be more scalable and easier to upgrade than legacy platforms such as SolarWinds, IBM, BMC, etc.

Cons

OpenNMS

  • 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.

  • Support for streaming data is on the roadmap must currently be addressed via a third-party app.
  • For some customers, a hybrid on-prem/cloud model may be a better fit than a pure cloud model. The onsite collectors offer some, but not all, of this functionality.
  • Tighter integration with third-party (AppDynamics, etc) and/or built-in app performance tools.

Alternatives Considered

OpenNMS

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.

Return on Investment

OpenNMS

  • We've been able to improve our customers' experience.
  • Because we're able to respond to issues quicker, we're able to better meet our SLAs.
  • We are able to see smaller problems and address them before they become big problems.

Zenoss

  • We're a reseller/Integrator, so this question has a somewhat different meaning to our business. For us, Zenoss Cloud allows us to provide a single Cloud-based monitoring platform that can address virtually all our clients' use cases, dramatically simplifying our training and staffing requirements. Instead of training Engineers on several platforms, including the installation of physical hardware/software, we can focus on a single platform.
  • The faster time-to-deployment and always-on cloud platform is a great fit for DevOps environments and newer software-defined data center platforms. The ability of Zenoss to support these environments solves what has been a major blind spot, slowing adoption of platforms that have been difficult to effectively manage with legacy monitoring platforms.
  • For clients, the ability to consolidate from multiple prem-based tools to a single cloud-based platform is huge. Eliminating multiple licenses and ongoing hardware & administration costs can show a 1-2 year ROI.
