Featured Reviews

Harrison Bulley - PeerSpot reviewer
Senior Infrastructure Engineer at Net Consulting
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.

Senior System Administrator at Interactive Group
Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Quotes from Members

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

Pros

"Macros and the ability to connect it to Google Maps are valuable features."
"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."
"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."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"The best thing about the solution is how it highlights errors, the issues, and what needs my attention. The solution directs me to areas that I should look for first."
"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"An affordable solution for small organizations to do basic network monitoring."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
"The solution is quite efficient."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"I would rate the overall solution ten points out of ten."
"Dashboard provides monitor of total assets."
"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."
 

Cons

"The installation and configuration are very complex."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"Icinga’s automation could be improved."
"The user interface should be improved."
"We have found some problems with Nagios, and support isn't very responsive."
"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."
"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."
"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."
"The mapping is a little hard."
"The dashboard should be improved."
"There is room for improvement in the graphics."
"t was a little hard to get our setup represented in the configuration."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"The dashboard and monitoring features 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."
"The scalability needs improvement, it's not scalable at this time."
