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

"Once everything is set up correctly, it reduces our MTTR by 50 percent."

"Centreon's most valuable features are preventative maintenance and cost-efficiency. Everything is monitored, and we get a log before the system fails. We have an opportunity to fix the issue and avoid downtime."

"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."

"In addition, the flexibility, customizability, and analytics of Centreon's dashboards are all very good. The dashboards help us see the whole network map, and that is quite valuable for us. In addition, the dashboards have helped to improve our visibility and ability to proactively ensure the right data is available at the right time... The flexibility has given us the ability to add in our own monitoring metrics and that has been quite interesting and very useful for us."

"Centreon allowed us to do it without having to look for another solution."

"Centreon provides timesaving and costsaving benefits as it lets us manage multiple devices on a single platform."

"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."

"It's a great product, it's very flexible."

More Centreon pros

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

"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."

"The best feature is that it is very relatable, stable, and scalable. The logger is a part of the software, but it's not the most important point of it."

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

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

"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."

"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."

More OP5 Monitor pros

Cons

"The reporting has room for improvement."

"They only sell four hour slots for support, so if you have just one question, then you need to pay for four hours."

"The most important issue is the capability to interconnect with other systems. It already exists for some of them. For example, the Stream Connector is something we use to populate data in another system. This kind of facility for connecting should exist for all products that it makes sense to have connected to a monitoring solution."

"It is necessary to improve service monitoring of database services in the free version."

"There are improvements that they need to make to their API. When we're using different systems and we want to disable monitoring for a specific server, we still can't do that through the API. That's something that's lacking."

"Where Centreon is weaker is that the initial deployment could be easier."

"Now that we got it, I haven't had time to work on it since it is a paid solution that is quite expensive."

"There is room for improvement in the area of artificial intelligence. The product gives us a lot of information, but it's only information. We want the product to do more auto-remediation."

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."

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

"They need to improve the dashboard interface."

"We do not get performance reports properly."

"They need to improve the dashboard interface."

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

"OP5 lacks some visualization, a feature that makes some other products nice. Op5 is built for purpose, which is fine, but if you compare it with some new products, the visualization is not so appealing, especially for management... If you don't need fancy visualizations, OP5 is fine."

More OP5 Monitor cons

Pricing and Cost Advice

"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."

"In terms of licensing, you have to think through if the components that need licensing are really needed. For example, the Map module: If you don't need a map to be shown, I don't see a point in paying for those licenses, if you just use it a couple of times a month or a couple of times a week... You can use the Centreon free version and get the main features. The licensing part is, I would say, only for bigger customers who have the option to pay more and who really need those kinds of modules, fancy reports, etc."

"The tool is cheaply priced."

"You purchase a package. You have a support contract (there is also a platinum support contract) and it is per module. That means you have to pay, e.g., for the MBI module or the BAM module. Or, if you want to save a lot of money, you can pay for IMP, which is the complete package."

"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."

"They only sell four hour slots for support, so if you have just one question, then you need to pay for four hours. Or, you need to wait until you have enough questions to fill those four hours. They are not flexible in this."

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

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

More Centreon pricing and cost advice

"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..."

"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."

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