Experience enhanced monitoring with real-time alerts and efficient support

I would like to see automation in the poller features, as currently, the poller is not automated. If we could automate the addition or removal of hosts in the poller, it would improve efficiency. Sometimes, Centreon does not show the status of services as updated, which should be addressed. Additionally, enhancements are needed in identifying configuration issues, providing real-time alerts in case of issues, and improving the HTTP configuration tasks, as Centreon does not currently display issues with HTTP links, requiring manual investigation.

Monitoring ease and cost-saving benefits enhance operational efficiency

The monitoring in OP5 Monitor is very easy because we can directly use custom plugins. We can write custom scripts and use those scripts directly. It's very low cost, open, and the dashboards are easy to see. We can extract the reports easily, and this is very easy to compare. Real-time monitoring in OP5 Monitor provides data every one minute or every five minutes, enabling us to get live data from the last one minute or last five minutes. OP5 Monitor gave us proper server availability, so we can always check whether a server goes down or the server CPU and memory decreases. Before reaching a particular bottleneck situation, we identified and fixed the issue, which helped us from a cost-saving business perspective. It helped us avoid application downtime.

Quotes from Members

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

Pros

"Centreon's most valuable feature is Opsgenie."

"The most valuable feature is the ability to build an abstraction of service visualization. You can add services to an entity called Business Activities and you can see the state of these activities."

"The downtimes feature is helpful. If the ISP is doing some maintenance on its network, we have the option to put downtime on the devices or the services, so we won't get any false alarms."

"The product is available in ISO image format, ready for deployment. Centreon also has a comprehensive guide and documentation that are simple and easy to follow."

"Another feature we use is Business Activity, which provides us with an end-user perspective when a service is down or isn't working correctly. This is helpful when monitoring the KPIs. When we see a device or server that isn't working, we find the root cause."

"The most valuable feature of the solution is that most of its plug-ins are free."

"What we like about it is that, whereas with Nagios, by design, if you have five or six data centers, you have to open five or six web pages to see what's going on, In Centreon, this is all included in one page, a single site, one dashboard. You don't have to jump from one specific dashboard to the other."

"During the day it probably saves us 50 percent of our time, and during the night it's even more."

More Centreon 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."

"We can also observe whatever we want, and there are no limitations."

"The API makes it pretty easy to integrate with any system."

"With limited hardware or a virtual machine, you can address a huge network, hundreds of thousands of elements that need to be monitored. Other commercial software is not on that level."

"OP5 Monitor is a great choice due to its being built on an open-source monitoring tool and provides ample opportunity for customization based on specific support requirements. It is also user-friendly and easy to manage with a wide range of plugins available for use. In comparison to other enterprise tools, such as Micro Focus, OP5 Monitor stands out for its features and cost-effectiveness, making it the best tool in the market. Customization is one of the key strengths of the tool and provides a lot of capabilities. Additionally, it is easy to find support and plugins for the tool through online resources."

"The best feature is that it is very relatable, stable, and scalable."

"Especially with the API, where I can use the data with many other systems, it's great."

"The monitoring in OP5 Monitor is very easy because we can directly use custom plugins; we can write custom scripts and use those scripts directly, it's very low cost, open, and the dashboards are easy to see."

Cons

"I went through a few things with them to do with Centreon MAP, to do with active polygons, being able to draw an area and make that active. The functionality was in the older version of Centreon MAP and in the new version, which was a complete rewrite, they dropped it."

"I would like to see a better UI, one which is more responsive."

"Centreon technical support is only available during Central European business hours. When it comes to critical business solutions, there should be a 24/7 hotline that customers can rely on."

"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."

"This solution lacks service monitoring in the cloud."

"To get it started is a lot of work, since it comes empty. We had to push information into it to make it work."

"The pricing setup costs and licensing weren't very good in the past."

"The Home view could be improved by adding customization functions that allow users to change the size of the widgets for a more uniform layout."

More Centreon 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."

"OP5 Monitor could include application monitoring in addition to infrastructure monitoring. If application business transactions were monitored, it would be helpful."

"The user interface is not what we are used to these days, and should be improved."

"They need to improve the dashboard interface."

"The user interface is not what we are used to these days, and should be improved."

"We do not get performance reports properly, which needs improvement."

"We do not get performance reports properly."

More OP5 Monitor cons

Pricing and Cost Advice

"The pricing is acceptable."

"The price is not too high. Licensing is driven by how many hosts you monitor, but because you can run the agentless version, you don't have to declare every host to Centreon, one at a time. That means you can drive your infrastructure supervision with a very low number of declared hosts."

"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."

"For more complex tasks, we use prepaid support days and ask Centreon to come onsite."

"It is perfect and very cheap if you are a little company or startup. After that, it is quite expensive for a big company."

"The solution is very effective, despite the low price."

"Centreon is an open source product. Thus, there is no need for licensing."

"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."

More Centreon pricing and cost advice

"OP5 has a very low price as a solution, compared to many other solutions out there."

"The cost of the license and support are separate. If you want platinum call support, it will cost more than a regular call. I did not opt for it, as it is an additional cost."

"It was not expensive. And because it's less demanding in terms of hardware, you don't have to pay for another SQL or other database license, and you can have a huge installation on one machine..."
