What is most valuable?

The most valuable features to us are the ability to improve memory usage, disc space usage, and the PDU load of each node.

How has it helped my organization?

Before using this solution, sometimes Jenkins went down and we didn't know the reason. We eventually discovered that the issue was disc space that exceeded a certain percentage. Now that we have Nagios to monitor the servers, we know if… more»

What needs improvement?

It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through. In addition, I would appreciate an FNP server for sending emails, which now depends on the resting servers for Nagios Core… more»

What's my experience with pricing, setup cost, and licensing?

Nagios Core is free to use.

What other advice do I have?

I would rate Nagios Core as seven out of ten because it was hard to configure and the implementation process itself took about two weeks. Also, the UI is not friendly. Other products have features that aren't included in Nagios Core. I… more»

What is most valuable?

The most valuable feature is the performance parameters of the system. Nagios Core ill continuous monitor the endpoint for most common parameters on an obsessive mode and… more»

How has it helped my organization?

Nagios Core informs me when my network elements are misfiring.

What needs improvement?

The core version is no match for the XI version. But the OEM should consider introducing some of the features of the XI version in the core version so that potential… more»

What's my experience with pricing, setup cost, and licensing?

Zero cost for the core edition but you need to know linux based apps configuration a=in general but in this case the installation and configuration guides make things a… more»

If you previously used a different solution, which one did you use and why did you switch?

What other advice do I have?

Definitely try it out if you have zero budget Even if you don't have a budget restriction please do give it a try

Which other solutions did I evaluate?

Tried many other similar products all demo versions hence did not take to production

What is most valuable?

* GUI interface * Notification capabilities * Real-time reporting

How has it helped my organization?

The benefits are that it's free and it allows us to monitor all of our production. So it gives us a comfort level of knowing that if there is a problem that pops up, we get notified.

What needs improvement?

In terms of any further features, that would bump us into their paid product. For what we get and what we use, and all the libraries that are available, it's pretty robust. However, for the version we're using, making it a little easier to… more»

If you previously used a different solution, which one did you use and why did you switch?

I had used this solution before and there wasn't anything in place here that was any good, so it was a no-brainer for me. My most important criteria when selecting a vendor are * flexibility * supportability * scalability.

What other advice do I have?

We have the ability right now to see and create reports to tell whether or not we're meeting our SLAs on our production servers, through it. That is something that we wrote and implemented as a plug-in. I would rate this solution a nine out… more»

What is most valuable?

* Historical Alert records/data * Plugins * Data sources (MySQL) * Grouping of services and servers We use the Alerting and Graphing to minimize the downtime. The old RRD… more»

How has it helped my organization?

It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place.

What needs improvement?

The GUI of the Core is still a long way off, but the features are 100 percent above average. It would be great to see better UI themes which could be configured by… more»

What's my experience with pricing, setup cost, and licensing?

The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server.

If you previously used a different solution, which one did you use and why did you switch?

We did not previously use a different solution. Nagios was the first solution that we started using 10 years ago.

What other advice do I have?

There are thousands upon thousands of plugins. This is a winning product. Nothing can match the plugins, even I have contributed about six plugins.

Which other solutions did I evaluate?

10 years ago, there were not too many options.

What is most valuable?

I like the way the solution sends alerts and how it keeps on escalating them. I also find the plugins by which you can easily add the divisions valuable.

What needs improvement?

I am satisfied, but I think there is a little bit of improvement that can be made. Lessening the price point would be an improvement. I would like to see more training videos. It is a vast product and it covers so many areas and so many kinds of devices, so I do understand that it's a challenge when… more»

If you previously used a different solution, which one did you use and why did you switch?

No, this is the first one that we started using. There was nothing that we have to complain about here from the past experience.

What other advice do I have?

In terms of advice, I'd say that you need to know what the plan is and try to understand from which direction you are going to monitor. And, to understand what additional things you'll probably want to do from your side, like putting in scripts and other kinds of automation. So the planning is… more»

What do you think of Nagios Core?

What is our primary use case?

Monitoring the critical services and network environment for a large multi-site company.  It is also used for troubleshooting issues and capacity planning.

How has it helped my organization?

Nagios allows IT staff and end-users to see the status of critical services on the network. It also can alert and notify selected users if critical services fail, reducing the mean time to recover.

What is most valuable?

Availability of additional plugins like SNMP for instant alerts and PNP4Nagios for graphs make this a powerful solution.

What needs improvement?

This is the open source product, so it's a toolkit rather than a complete solution. See Nagios XI for a more complete version. 

For how long have I used the solution?

More than five years.
