OpenNMS Reviews

It supports all the device models unlike cisco products

We need to compile and set everything manually ... nothing comes as predefined

Vendor neutral is the major benefit... use friendly and couple of code related issues and bugs I am working with OpenNMS

It has a very good UI.

With what I worked, alarms , polling were very well implemented.

It has very vast functionality.

Eclipse integration wasn't made easy.

Without IDE , its very tough to navigate through code base.

However, I tried to import it in Eclipse, but failed with so many errors in hand.

And I had to use it without IDE.

We were using it for showing packet data, polling , alarms, charting etc.

It was the front end .

It is open source resources, that easily permit to resolve all the appeared issues by yourself.

Sometimes is difficult to acquire a full coverage of desired infra.

Network infrastructure monitoring

Infrastructure monitoring. It helps to find the critical points.

It's very easy to configure. Onboarding a server is pretty much easy. Just give IP address/Hostname and provision. That's it.

UI can be more realistic and colorful like Ops-Genie.

Nothing.

Monitoring of different servers and switches. Getting alerts and usage in meaningful graphs.

The usage of powerful SNMP protocol, often no so appreciated, gives an amazing way to monitor and collecting data and alerts from different kind of devices. ONMS helps enterprise architecture to have all in control.

Some configurations can be a bit hard and not intuitive for who in new inONMS usage.

The UI can be re-arranged in a more modern way.

Fortunately problems are not so much, but the UI is the one that I’ll change. Often some devices are not so intuitive via SNMP and users can have difficulty to monitoring them as is simple to collect a Linux box.

Forecasting resources by analyzing collected data, is one of the benefits, but cold be improved.

Monitoring platform to monitor networking products

Nothing to be honest..all good ..its worth product

Network device monitoring

There is a lot of helpful documentation. So, it's most likely to find answers to the questions we have during the customization of the OpenNMS system for the first time.

There is a steep learning curve to use opennms. At times, we get overwhelmed with all the features. The XML configuration files are a bit too much at times.

Prepare the requirements well before. Opennms is really useful when you know most of the requirements before.

Its a open source. So, we used it to test the devices that are not posting for the last 24 hours. As we need to report on these devices. Its advantage is, it comes with a rich UI. I personally liked to notification system.

Lot of features like performance management,path outage,discovery,dashboards

Delay in alerting system, interface limitation,limited resources for development, here nagios will come in rescue

Go for it

Network discovery,trend analysis, performance

It allows you to add numerous devices, wide range of monitoring services and date analytics features.

Delayed alerts, not so gOod UI & limited development community.

It helped to identify issues in the network effectively. Traffic & date monitoring services are invaluable.

Very powerful open-source monitoring solution; relatively easy set up, clear dashboard.

Would not run when Tomcat was already running; had to start prior to starting Tomcat. Setting up JMX monitoring proved difficult. Current documentation (for Windows) lacking.

Considering its open-source status and fairly easy setup, I would recommend trying OpenNMS when looking for monitoring solutions.

Monitoring internal servers, instances of Tomcat, and web applications.
