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 use the product to monitor server applications. 

I am impressed with the product's alerts and reports. 

The tool needs to improve the integrations. 

The tool is stable. I would rate its stability a six out of ten. 

The tool's setup is straightforward. 

I would rate the solution's pricing an eight out of ten. 

I would rate the product a six out of ten. 

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.

We use Nagios Core to detect any issues in our infrastructure, software, system service, and network issues. It is a centralized monitoring service.

The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want.

Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI.

I have been using Nagios Core for approximately eight years.

Nagios Core is stable.

The scalability of Nagios Core is very good. We can add as many hosts as we like, and we can work with the concept master and client. It's very scalable and we have added the SentryOne as another layer. It's become very easy to use.

This solution is used by two engineering and three technicians. It is not used for end-user.

We use the open-source version of this solution and there is a large community that can provide support for any of our issues.

I am using SCOM in parallel to Nagios Core, it's a monitoring solution by Microsoft. However, I prefer Nagios Core.

Nagios Core is deployed in a Linux operating system and it is simple to do. For a medium-sized infrastructure, the deployment can take a day.

The enterprise version has technical support. The version we are using is free.

The free version of the solution does not have an interface, but the paid version does.

I would recommend this solution to others.

I rate Nagios Core an eight out of 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.

We used Nagios Core to monitor our servers in other countries. Our main server is in Cairo, while we monitor other servers in Germany, which are hosting Jenkins and other web services to make sure that the infrastructure is stable and if anything goes wrong it reports it automatically.

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 anything goes wrong it can solve the problem before it happens.

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

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. If it comes with its own FNP server, it would be much better. Also, if it can be installed in other cores, that would be awesome but right now it only uses Linux.

Alias excavation and configurations from the wall rather than the server itself would be great improvements. Also, general UI enhancements and better UX, user experience.

It's stable because it's a Linux based code, which is very basic. It doesn't have many big features, so it's stable. You can add a node in less than half an hour, I think.

We're only currently using Nagios Core on one to ten servers. In the future, we may add more nodes.

I haven't tried to contact support. I was searching on the support forums, but that was not for me. I tried many solutions from the support forums. One of them is working, but only after a long time.

The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to. I had to install them one by one on the app to configure the complication on the app that was solved to authenticate Nagios on the central app. It comes with regular users in files and in order to authenticate, you have to make a lot of confirmations, using Apache as well as Nagios. This was all very hard, and it took me a week to configure it.

I think deployment took about two weeks at the most. We did the deployment by ourselves. We have two people for deployment and maintenance.

Nagios Core is free to use.

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 think that one was the easiest to restore. Also, Nagios supports only Linux, not A/UX. It can't be installed on the servers. If they supported all of these things, it would be much better.
