ManageEngine OpManager vs. Nagios Core

Manage Engine OpManager is better suited to serve server and network admins at organization to monitor their servers and network devices. It helps us with compliance with the reports available like utilization reports and capacity planning reports. It helps you to keep track of what all process are consuming the resources. It helps you in monitoring what is happening in your switches, routers and firewall

Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.

As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.

Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.

• It measures the CPU utilization of hosts, the network bandwidth utilization of links, and other aspects of the operation
• It often sends messages—sometimes called watchdog messages—over the network to each host to verify if it is responsive to requests.
• Set Up Notifications And Reports.
• OpManager offers a set of advantages that allow it to adapt to the needs of the company, guaranteeing effective monitoring of the application networks used in our organization.

• Monitoring of services is one of the biggest benefits for our company. Being able to respond in a timely fashion keeps business smooth.
• Hardware and device monitoring are easy to set up with proper parameters.
• Notification to key staff to be able to respond quickly makes issues go away faster.

• Alerts has to be configured correctly otherwise unnecessary bombarding of alerts can cause inconvenience.
• The server on which ManageEngine OpManager is to be deployed should have higher resources as monitoring a large number of devices may slow down the performance of the system.
• Configuring the advanced features may require a learning curve.

• Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need.
• Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical.

This product works very well for our organization, and it would be hard to not have a tool like this going forward

We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.

The rating I provided is based on the product quality, experience (I have been using OpManager for almost the last 4 years), and relevance of the information/response I generated through Manage Engine OpManager. I have also received good support from OpManager.

The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.

At first, we were not able to add our Avaya switches to the configuration backup module, our partner tried to help, but they did not find the solution, we had one remote session with tech support of ME and they solve the problem.

I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.

During our competitive analysis, we found ManageEngine OpManager was not expensive compared to other vendors. At the same time, there was no compromise on the features such as customized reporting or configuring alerts per our clientele's unique requirements. These are our client words "Other vendors ask us to pay more $$$ for enabling additional email alerts".

Because we get all we required in Nagios [Core] and for npm, we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].

• I don't know if you can calculate ROI with a monitoring solution, there are more factors to calculate.
• We found a really big problem with a network switch (faulty transceiver) in a trunk configuration with OPManager. this caused us serial troubles with the overall network stability.
• We are loosing around € 3.000 to 5.000 per hour if our network is not working so this was a great help to fix this issue
• Our label printers are really important to monitoring in our warehouse system, this makes OPManager a great solution for that

• With it being a free tool, there is no cost associated with it, so it's very valuable to an organization to get something that is so great and widely used for free.
• You can set up as many alerts as you want without incurring any fees.
