Nagios Core Reviews

Our company is sales based and we offer a test service to our enterprise-level customers. We use the solution to monitor our test servers and have 25 users throughout our company. 

Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work. 

The user interface could be more interactive because it is pretty basic. 

I have been using the solution for two years. 

The solution is very stable so stability is rated a nine out of ten. 

The solution is scalable with no issues. 

We have not needed technical support. 

The setup process is very simple. 

We implemented the solution in-house. 

The solution is expensive so pricing is rated a one out of ten. 

I rate the solution a nine out of ten. 

I use Nagios Core for basic monitoring of my systems and services.

What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services.

I have found Nagios Core to be challenging in terms of its centralized architecture and configuration complexities, especially in a Microsoft environment. Making optimizations or changes often requires reinstalling the server, which can be inconvenient.

I have been using Nagios Core for over a year.

It is a very stable product. I would rate the stability as a seven out of ten.

Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers. However, it is scalable in sizing, allowing for easy updates and upgrades without much complication. Just need to adjust settings in the software during the process. I would rate the scalability as a six out of ten.

I have worked with Centreon in my organization as well.

The installation of Nagios Core was relatively straightforward with no major complexities. My team managed to install it within a day. Maintaining it is straightforward for us. We don't do frequent updates; it is a one-time install. The only ongoing task is occasional security adjustments, mainly related to access control. 

I would recommend Nagios Core for CentOS organizations, especially for simpler evaluations or smaller projects where a significant investment isn't required. It is suitable for those without extensive monitoring needs. Overall, I would rate the solution as a six out of ten.

Our primary use case for this solution is an APM for application performance monitoring. For example, we deployed the solution on-premises so we could observe the solution. We look at the threats at the web containers, the data source, and all these components under this monitoring.

The application performance monitoring feature is valuable. We primarily use it for user experience monitoring and determining which layer the problem happened to resolve it.

The initial setup process could be improved.

We have been using the solution for one year.

The solution is stable.

The solution is scalable but we are still familiarizing ourselves with tool and have not scaled largely yet.

We do not have experience with customer service and support.

The initial setup process could be easier. For example, the setup for infrastructure monitoring is straightforward, but in the case of application monitoring, it is more complicated.

We primarily implement through vendor teams.

I rate the solution an eight out of ten. The solution is good, but the initial setup process could be easier. I recommend the solution to users who want a more diverse environment for monitoring.

We use Nagios to monitor networking infrastructure and services.

The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful.

The mapping is a little hard.

I've been using Nagios Core for three to five years.

Nagios is 100 percent stable.

Nagios is appropriate for companies of all sizes, but a larger enterprise might require a bigger IT team. The largest team I've seen was 50 people. You can easily scale Nagios up, but I've never done it. 

Nagios support is good. They also have a complete knowledge base, so if you need to figure something out, you can find everything about the solution in one place.

I used Pandora about seven years ago, so I can only speak about the capabilities of the solution as it existed at the time. Pandora was excellent, but the documentation was too complicated.

It depends on infrastructure, but normally Nagios is easy to deploy, and I could do it by myself. It usually takes two or three days, but I needed a week for one deployment. You need to install and configure everything and deploy the agents on various servers.

After deployment, you need to do periodic updates and patching. You download the latest pack from the Nagios server with the client. You can do an ATT update depending on if you have Red Hat or Windows between the platforms.

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.

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. 

Our primary use case is for Infrastructure monitoring.

Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well.

Nagios Core is very configurable. Whatever you want, you can do it. We have multiple agents and scripts available with the Nagios Core portals and the internet. The cost is also very acceptable.

Datadog provides the compatibility to integrate with these big data platforms like Cloudera and others. These services are very efficient and they provide customer support with it. In this case, I believe Nagios Core will need to provide an option for big data platforms in the future.

I have been working with Nagios Core for the past five or six years.

Nagios Core is highly stable.

Nagios Core is scalable for our purposes.

The implementation was completed in-house because previously it was an open source tool. We can configure it to our own needs, based on our own requirements. The only task we had to complete is creating the script and using the tool. We had alerts created for our mobile phones, email and dashboard.

When we look at pricing version eleven requires purchasing a license. With version seven no license was required since it was open source. When you upgraded to the licensed version only then did you pay for a license

I would rate Nagios Core a nine out of ten.

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.
