Nagios Core Reviews

It is stable and fit for purpose. Various plugins are available as per your need in the open source marketplace to use and customize according to the need.

We use other enterprise products for most monitoring activities. However, Nagios has been the product to go to if we need a cost effective solution that can directly fit our needs. We use it in our business operations center to view dashboards (i.e. it provides a Google map view) of critical systems within stores.

Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source.

We use only Nagios Core.

We have had no issues with the deployment.

Stability wise it just works without any major maintenance.

It's highly scalable and will scale according to your needs.

It is an open source tool which provides capability to customize it according to the needs. So internally you need to have expertise to consume its servers unless you go for the paid options.

You should be sure that you have the expertise to customize it, and I would recommend the paid-for Nagios XI for the additional support.

This is a fit for purpose product which means that if you have a definite list of requirements and are not willing, or unable, to spend money on big enterprise tools, then Nagios is a tool to go to. Also, any changes to the customization means that you need to have the skill sets internally within the organisation to effectively use it. Otherwise it's a great open source product.

We mostly use Nagios Core to integrate with Python and Bash Script. If there is a requirement from the client to monitor these services, and Nagios Core does not have the features, we integrate Python and Bash Script with Nagios Core to monitor the services.

Nagios Core does not have a graphic display.

My company has worked with Nagios Core for the last six years.

I rate Nagios Core ten out of ten for stability.

I rate Nagios Core ten out of ten for scalability.

Nagios Core's initial setup was not difficult for me.

Nagios Core is a cheap solution.

Nagios Core is a world-famous open-source monitoring tool. It is easy for us to showcase a Nagios Core demo to the client.

Overall, I rate Nagios Core ten out of ten.

Our main goal with Nagios is to keep a close eye on our servers and the services running in our AWS environment. We’ve got a mix of Windows and Linux systems, each running specific services, and Nagios alerts us whenever something isn’t quite right. It’s also great for monitoring the sites we host on IIS. We've relied on Nagios since 2013, and it’s been a real game-changer when you have so many moving parts to track.

I can say Real-time Monitoring and Alerts, Comprehensive Coverage, Cost-effective Solution, Historical Data and Analysis, and Reliability and Stability

The value of the solution is that we get timely notifications if there are any issues and they can be solved immediately. Nagios provides all the plugins required. 

The UI is a little outdated so it's not as user-friendly as it should be and the graphics should be displayed in a better way. 

I've been using this solution for 10 years. 

The solution is stable and reliable. 

The scalability of this solution is impressive, particularly because it allows us to expand our monitoring capabilities as our infrastructure grows. With Nagios Core, we can easily add new hosts, services, and devices as needed, ensuring that we maintain visibility across an increasing number of systems. While configuring additional checks can require some setup time, the flexibility it offers makes it well-suited for scaling. Additionally, the open-source community provides plugins and resources that help address scaling challenges, making it adaptable for both small and large environments.

Because the solution is open source, there's no direct support from Nagios. We post our questions to the community and that provides sufficient support. 

Positive

The initial setup is easy and straightforward. Deployment probably took us an hour or two and was not implemented all at once. New areas come up all the time that require monitoring so we research which plugin will be useful and implement that. It's enhanced gradually whenever we have a specific requirement. The implementation was done in-house. There is some maintenance involved, including for the upgrades. I manage the solution but there's a development team to monitor the services, around eight to 10 people. 

The product is open-source, so it’s completely free to use. We have it deployed on an Amazon server, which costs us a small amount approximately $30 per month for AWS hosting

We tested ManageEngine and another open-source product like Zenoss but we found Nagios easier to set up and manage. 

I recommend this solution because it’s very user-friendly. There are excellent resources available online, and it provides everything we need to meet our requirements.

I rate this solution nine out of 10. 

It is used for monitoring services on a bunch of virtual machines.

In terms of the version, we're fairly up to date. We are perhaps not the most up-to-date, but we're fairly current.

It provides visibility of the platforms.

It is fairly easy to set up, and we can monitor pretty much everything we want to.

We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier.

In terms of new features, we're just using it for what it is. We are using what we've got now. We don't have any additional requirements as far as I'm aware.

I have been using this solution for four or five years.

It is fine. There are no concerns there. Our biggest challenge is that we get a lot of timeouts, but that seems to be because of our network setup. There are a whole bunch of spurious events being reported, but they're more timeouts in getting to the Nagios agents.

It seems to be all right at the moment. We don't seem to be having any problems with that. We have upwards of 20 users, and it is being used on a daily basis.

I have not contacted them for a long time.

Nagios is the first one.

From what I heard, it didn't seem difficult to set up. It was quite straightforward.

We're still rolling out and deploying new instances of VMs that we want to monitor. It's an ongoing process.

We deployed it ourselves. Its maintenance is done by one or two people.

We are using the free version.

I would recommend it to others. It does what it is supposed to. It is pretty good. 

I would rate it an eight out of 10.

We use Nagios to monitor hundreds of CentOS cloud servers (and a few Legacy Windows servers). Nagios is monitoring well over 5000 service endpoints. Some plugins were handwritten in PHP, Perl, Python, Java and Bash.

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.

• 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 Graph module is now used by Grafana. We outgrew the old PNP4Nagios a few weeks back. 

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 Netadmin or instructions that help combine graphs and Nagios.

I have never had stability issues. Nagios has been stable for over 10 years. Although, we never left it running for more than two weeks without uploading new services, plugins, and threshold changes, then restarting it..

No scalability issues, though it is a bit slow due to latency. However, after tweaking the Nagios and off-loading the graphing to NPCD, I was able to scale the Nagios to more than 5000 services checks with 0.5s latency.

The end-users love quick alerting and Grafana dashboards.

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

Since its Nagios, it is a bit time consuming, but worth the effort. It took a few hours setting up the entire environment, including RRD, PHP, Apache, Nagios, PNP4Nagios, Perl, Python, OpenSSL, etc.

We did an in-house installation.

We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting.

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. 

10 years ago, there were not too many options.

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

Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs.

Cloud monitoring is an area for improvement because there aren't too many plugins available.

I've been using Nagios Core for almost two years.

It is a stable solution, and I would rate the stability at eight out of ten.

I would rate the scalability at five out of ten.

Nagios Core is an open source solution, and there are no licensing fees.

Nagios Core is a good tool overall, and I would rate it at six on a scale from one to ten.

I'm primarily using Nagios Core to monitor infrastructure like servers, virtual machines, and telephone usage like IP-DECT antennas. I don't use all of Nagios Core's data functionality. I only use the monitoring features.

The dashboard and monitoring features could be improved.

We've been using Nagios Core for about five years. 

Nagios Core is stable.

The Nagios Core setup is complex, but I can handle it all myself. 

I rate Nagios Core seven out of 10. Nagios Core is not easy to use, so I don't recommend it for everyone.
