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

"We have found the solution to be stable."
"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"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."
"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."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"Icinga does the job and is fairly stable."
"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 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."
"I would rate the overall solution ten points out of ten."
"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."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."
"The reporting structure and the feature set are valuable to me."
"Provides timely notifications."
 

Cons

"We have found some problems with Nagios, and support isn't very responsive."
"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."
"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 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."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"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."
"Application level monitoring is limited."
"The mapping is a little hard."
"The interface could be improved."
"There is room for improvement in the graphics."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"I would like to see more training videos."
"The scalability needs improvement, it's not scalable at this time."
"t was a little hard to get our setup represented in the configuration."
