There is room for improvement in the graphics.

Another are of improvement is the ability to host and service by other web interfaces rather than configuration files.

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.

Considering my utilization of Nagios on a daily basis, it would be really great if Nagios can concentrate on the following areas of improvement:

  • Custom availability report and export as PDF
  • Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems. In my present configuration, I've observed PHP level coding issues. I'm able to fetch all Nagios data into the Nagios Digger database (mariadb in rhel7) successfully, but found difficulties fetching and replicating it into the PHP front end. I've already contacted its author and coordination is in progress to make it available for the community.
  • SMS tool integration with Nagios

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.

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.

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 configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do.

Dashboards and HUDS could use a facelift to be more in line with next generation monitoring tools that really have amazing UI’s. Sadly, many people may think that Nagios itself as a tool may not be sophisticated because it lacks the typical definition of a sophisticated UI.

Nagios has significant capability and opportunity for customizations to really “dial-in” the implementation to suit your specific enterprise requirements. But, enabling many of these capabilities requires an SME and to sustain and support the implementation requires effort and manpower. The larger the implementation and more extensive the customizations- the more resource intensive the deployment will become.

Application level monitoring is limited.

Partner Technical Support & Escalation Manager at a tech vendor with 51-200 employees

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.

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.

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.

Generally, it does what I need it to do, but better error reporting would be great. It's so flexible that I do not use half the capability that it has. Also, Nagios 4 does not work with NConf or Adagios so we haven't upgraded yet.

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.

Computer Engineer at a tech services company with 501-1,000 employees

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 you want some kind of integration, or add a plugin, to always have documentation. But, yeah, as much as possible on the documentation, if it can be done better, that would be good.

If there was more application monitoring, it would be much better.

I like to have the option to configure Nagios using the web interface. Although I agree that the CLI gives a lot of customization options, I'd like to take a break from looking at lines of words. Also, configuration via a web interface could be expanded to not-so-Linux-literate users.

Nagios was not built with scalability in mind. It does not work in a distributed fashion, and fixing this issue would probably require rewriting a big chunk of its code. There are other solutions, born as a fork of Nagios, that do this but it would be great if Nagios could do it.

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 customers are actually compelled to to consider upgrading to the enterprise version

Nagios' great customizability is also one of it's greatest drawback. In the early days, installation and configuration of nagios was not for the faint of heart. You need a lot patience and system administration skill to figure out what gets into what file. This is still true today, as some still install nagios from source. Aside from installation, configuring nagios from the command line is very tedious, time consuming and prone to user errors. The core nagios installation from source does not provide an integrated management system for nagios, and you have to install these systems separately from nagios.Nagios is a great product. I would highly recommend this to organizations which requires a great deal of flexibility in terms of customizing their network monitoring system.

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.

Default interface is clunky and slow. Can be a steep learning curve if you haven't worked with it before. Adding devices or services requires reloading the config or restarting the service. Would like for this to be more dynamic. It seems that most of the new development is going towards Nagios XI(paid enterprise version) rather than the opensource nagios. Would like to see some of the newer ideas in Icinga and/or MK livestaus integrated into opensource nagios. View full review »
