Nagios Core Reviews

We primarily use the solution for monitoring ops for computers and our server. We're considering adding other device monitoring as well and at points of sale.

The solution is quite efficient.

The system's alerts are quite good.

The solution is very complete and mostly easy to manage.

The latest version is a bit more difficult. There have been some changes that have not really improved the solution.

We have a new manager coming in, and they will watch and see over the course of the year if the solution needs any specific improvements. We're still in the process of testing the solution.

The implementation and deployment might need to be slightly improved.

It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly.

It would be good if the solution had some sort of alarm system to alert managers to any issues. We get good alerts, they just need to get to the right person more efficiently.

We've used the solution over the last 10 months or so. It's been almost a year. We initiated the product in 2020.

The stability of the solution is quite good. We haven't had any issues per se. It's been reliable.

We haven't had any issues with scalability. If a company needs to expand it, it should be able to.

We have about 100 hosts and about 10 servers at this point and maybe 19 at the point of sale.

We don't really have technical support from the solution. We rely instead on learning the solution and focusing on documentation if we need assistance. There's also a community online that's quite helpful.

Their documentation is very complete and they have pretty good policies in place.

We did previously use a different solution. We still use it. It continues to monitor our network. We have a new CTO that is looking to make changes. We're evaluating more economical options.

The installation is initially a little bit complex.

The process took several months. Originally, we were using Linux systems.

We didn't have installers or another company assist us. We handled the implementation ourselves.

We're just customers and end-users. We don't have a business relationship with Nagios.

We're using the latest version of the solution.

We're still in the early days in terms of usage. We're still feeling the solution out and testing it for its acceptability within the greater framework of our organization's requirements. We're looking to test it at the point of sale to see how successfully it operates.

Overall, I would recommend the solution to other organizations.

I would rate the solution eight 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 for one of our customers to monitor all the servers, firewalls, routers, and cameras. While monitoring the server we get alerts, this enables us to raise a ticket and notify end users that we are aware of the issue before they need to notify us.

We have 80 people using the dashboard and getting the alerts. Depending on the number of servers, routers, and firewalls we are monitoring in current clusters. When one cluster goes down, it will automatically take data from another cluster. 

We support 24/7 because our client is a financial company, if the critical servers go down, they would face financial issues. 

The features of Nagios Core that we find most valuable are the plugins we use, we can check the uptime and see how many servers and routers and create groups accordingly. From these groups, we can check how many servers and routers go down. 

We also like the alerting features. One of the dashboards they provide monitor total assets and how many are up and how many are down.

If we need to process quicker, we use third party plugins to avoid downtime.

Nagios Core would benefit from aggregations if a particular server goes down. 

Comparing Nagios UI and Nagios Core, in Nagios Core we need to do some coding while Nagios XI has everything in UI. If you go with Nagios XI the developer task is minimized because they help provide the UI. With Nagios Core, we need to log into the Linux servers and we need to change that particular directory. We need to write a code for each and every server.

I have been working with Nagios Core for two years.

We deploy Nagios on a cloud, so there are features like plugins. The help desk tickets plugins so we can monitor the lock files as well from main server and create dashboards.

The security-related features also are there to monitor antivirus and install or not on each and every server. 

We were working with ELK. Due to costing we switched to Nagios Core because it is free for the alerting feature. 

The initial setup of Nagios Core is straightforward. We installed as per the steps mentioned in Nagios' documentation. It can be deployed in a day.

I completed the installation myself.

Most of the features in Nagios Core are free. Most plugins are free. 

When considering Nagios Core you should consider how many servers, firewalls and routers you need to monitor. Then determine which services need to be monitored by Nagios Core and how many service alerts are needed so you can create clusters and keep your gig size and RAM size accordingly.

I would rate Nagios Core a 7 out of 10.

The most valuable features are the reports and the way it generates the report in a graphical manner. The creating availability, the ratios, the uptime, downtime, and the outages.

Most of the issues have been covered through Nagios XI, but they could select some of the small features that are in the paid version and include them as part of Nagios Core.

Especially the graphical user interface in terms of configuration when you add in hosts, you have to use CAC and CLI to add hosts. You could use the GUI to add hosts instead.

The scalability needs improvement, it's not scalable at this time.

I have been working with Nagios Core for a couple of years.

We are using the latest version.

Nagios Core is a stable solution.

This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it.

It's not scalable, which is important these days when you want to see more data and how your network is performing.

We have not contacted technical support. Most of the online documentation is helpful.

The initial setup is pretty straightforward.

I can't say how long it took to deploy as we had several deployments at the same time, but it was not a problem at all. We didn't have any issues.

We are using the open-source, unpaid version.

I would recommend it for small network deployments or if you have other open source applications or other metrics like utilization, CPU. So if you're running alongside other open source applications and in the small space, it works. But anything beyond that is not recommended.

I would rate Nagios Core a six out of ten.

We are using Nagios Core mainly for servers. We check the network hardware connectivity. We check for the availability of the network and for hardware failures.

We have deployed Nagios Core on a VM and it's working very well. The specs of the VM are very low because it doesn't require so much storage

The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good.

Nagios Core can improve the graphical interface, it would make things a little easier.

I have been using Nagios Core for approximately five years.

The stability of Nagios Core has been good in our usage.

Nagios Core is scalable for our needs. We don't have many servers and network activity, we have approximately 200 nodes, and it's fulfilling our requirements.

We do not have plans to increase our usage of the solution this time but maybe in the future.

We do not have support for this solution, it is free.

I have not used another solution previously.

The initial setup of Nagios Core is not complicated, once you are used to it, it can be easy. The full implementation took us approximately three hours.

I rate the initial setup of Nagios Core a three out of five.

We maintain Nagios Core in-house.

We are using the free version of Nagios Core.

I have evaluated other solutions.

This solution can meet basic requirements. If someone is using it on a larger scale they might have difficulty managing it.

I rate Nagios Core a seven 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.
