Harrison Bulley - PeerSpot reviewer
A stable, scalable and cost-effective solution that helps with inbuilt scripts for easy modification
I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built.
Nishith-Vyas - PeerSpot reviewer
Valuable reporting and alert system with room for PDF export improvements
The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"There's a module called Icinga Director, which helps us configure the product using an intuitive interface through clicks instead of creating a text configuration. It's very helpful for us."
"We have found the solution to be stable."
"I like the ability to amend and adjust things really easily, which is useful in a case where you could make it auto-discover and then set a template to say all of these applications or servers under this template have an automatic threshold set that you’d set up manually."
"The apply rules feature saves a lot of time."
"The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated."
"Macros and the ability to connect it to Google Maps are valuable features."
"Icinga has multiple automation and integration features. There is an API for everything and a web UI for configurations. The APIs enable you to automate tasks in Icinga. We can also use plugins to talk to the API. The Icinga Director talks to a database in the background, and you can import settings from the CMDB to all systems in Icinga."
"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"I would rate the overall solution ten points out of ten."
"Dashboard provides monitor of total assets."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"It is fairly easy to set up, and we can monitor pretty much everything we want to."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"The reporting structure and the feature set are valuable to me."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
 

Cons

"We have found some problems with Nagios, and support isn't very responsive."
"The solution lacks many features important to higher-level IT management and network support."
"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."
"Icinga’s automation could be improved."
"Icinga is a complex solution that's hard to learn. It's a powerful product for monitoring, but new users will have a hard time figuring out what to do."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built."
"The tool currently fails to provide notifications to users."
"The initial setup process could be easier."
"It is a bit slow due to latency."
"There is room for improvement in the graphics."
"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."
"The tool needs to improve the integrations."
"The user interface could be more interactive because it is pretty basic."
"The dashboard should be improved."
"I would like to see more training videos."

"Nagios Core is a cheap solution."
