DX Spectrum vs. OpenNMS Meridian

As I said before, not only for Spectrum, but for any monitoring tool, you need to know what is critical in your environment and think about how exactly you should monitor and treat it. If you have done that, everything will work just fine.

• Well Suited - Networking Monitoring
• Less Appropriate - When you need to customize some monitoring and to update the version

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.

• Polling and traps can be configured to take heartbeats at specified intervals and notify on an event in real-time, respectively.
• Topology of devices gives a high-level overview of network architecture.
• Discovery of devices is simple and secure with the use of community strings.
• Details can be added per device or alarm type for actions to be taken to make troubleshooting easier.

• 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.

Other tools I have used are more server/application-centric. CA Spectrum seems to work effectively and efficiently for network devices. Notification delays can be set to grant grace periods in case of network blips or false positives, which occur ALL the time. Other monitoring tools send event notifications immediately and would clear instantly, which while on-call can wake a technician for no reason.

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.

• Proactive monitoring for networking
• To many times to plan an update

• 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.
