Quotes From Members

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

Pros
"The dashboards are valuable because they ease troubleshooting and viewing. It becomes easier to locate the source of a problem... The dashboards make it easier to communicate with our clients. They don't want to see the alert console, they want to see a beautiful dashboard representing their network and their business and to watch it in case something is wrong in their environment.""The single-pane view provides us a view of all of our network infrastructure, and it is one of the most important tools that we use to see the status of our customers' networks.""Centreon helps me detect where the problem is quickly. When we resolve a problem quickly, this lowers our overall costs.""We have the business activity monitoring, the map, and the MBI modules and they are all very good.""The customizable reports and dashboards are really flexible. We started this partnership with Centreon, when we were looking for a solution, because of the flexibility of the reporting. That's what we found to be most attractive in the solution. You can display the data as you want.""You can concentrate and orchestrate several other solutions from other vendors. You can consolidate those solutions all in one place, then maintain and monitor from that single point. This creates ease of use. It is a very powerful solution from this point of view."

"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.""The most valuable features are the reports and the way it generates the report in a graphical manner.""The solution is quite efficient."

More Nagios Core Pros »

"It monitors and continuously tests everything that is of importance to you and your users. It could be everything from monitoring disk space to CPU usage to memory. It could include determining if the response time in your e-commerce platform is quick enough, or whether you have too many bounces from some of the pages on your website. You want to monitor anything that could cost you money or time or resources. You can do that with this system. It's very flexible.""The API makes it pretty easy to integrate with any system."

Cons
"Opening a ticket on the website of Centreon can be difficult for my colleague, but not for me because my English is good. However, my colleague doesn't speak English well, as our company is in Quebec and our first language is French.""Currently, we have to go through all of the different templates and take a look at how the template is configured, and how specific parameters may change across different templates with different precedents, megatons, etc. It's a lot of work and involves trial and error. I wish they could simplify the process.""Improvements are needed in the area of cloud monitoring, as that's a newer feature.""Centreon is actually missing an easy way to create a trendline for the metrics. Actually it is possible to create it, but you need a good knowledge of math, Centreon, and RRD.""I would like to see more plugins. That is something it needs. There is also room for improvement through dynamic thresholds, or self-discover thresholds. I would also like to see a discovery feature that could map the whole network environment and automatically suggest things.""During the initial setup we faced some issues. Part of it was because we had to become more knowledgeable in the solution. There are some gray areas and if you don't know the product well you may have issues. Another part of it was some bugs that we came across, although that's part of every software solution in IT nowadays. But the initial setup could be easier."

More Centreon Cons »

"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.""The scalability needs improvement, it's not scalable at this time.""Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."

More Nagios Core Cons »

"IT environments today are in constant flux. This is driven by the newer cloud technologies such as Kubernetes and Docker, etc. The whole Nagios-based monitoring system that OP5 is created on top of, is based on a host-service model. There is a need for a strategy on what to do with more dynamic environments. There is some cool stuff going on in that direction.""The user interface is not what we are used to these days, and should be improved."

Pricing and Cost Advice
"If you need basic monitoring without dashboards, just monitoring, the plugins are very useful and really cheap. If you want a more complete solution with dashboards and reporting, the EMS solution is great and it is not that much more expensive. It's a good value. Really good.""Their licensing model is really easy. You have one license and you have access to all the features, compared to other tools where you have to purchase add-ons.""The pricing works out well for us, given our environment and where we are.""Centreon is better than Nagios XI in regards to cost and support response times, when you have a problem. If you have a problem, it costs money to contact the Nagios XI support.""Centreon is always available to develop new plugins when needed. The most important thing is that their maintenance account yearly subscription fee includes the fact that they will maintain the new plugins that you requested them to deliver."
