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

"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"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."
"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."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"An affordable solution for small organizations to do basic network monitoring."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"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."
"The apply rules feature saves a lot of time."
"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 good thing about Nagios Core is it covers everything."
"I like the way the solution sends alerts and how it keeps on escalating them."
"Dashboard provides monitor of total assets."
"The application performance monitoring feature is valuable."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
 

Cons

"The installation and configuration are very complex."
"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"The user interface 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."
"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."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"The tool currently fails to provide notifications to users."
"The scalability needs improvement, it's not scalable at this time."
"The interface could be improved."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"The UI is a little outdated and graphics could be displayed in a better way."
"I would like to see more training videos."
"Would benefit from aggregations if a particular server goes down."
"The alerting mechanism in Nagios Core could be improved."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
