Sulesh PK

Monitoring and Operations Pilot at Egis S.A.

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.

Quotes from Members

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

Pros

"We use the remote server functionality on some customer sites, because you can see an independent view and are not dependent on a single connection. If you have branch offices or bigger office outside your headquarters, you can use remote servers because if the connection is broken or disrupted, then remote server will obtain a view of your environment and server availability. This is a good point against using other solutions. Because with other solutions, you don't have this feature. Then, you will be blind if you have this type of a situation."

"We have all our tickets inside Centreon in real-time and can monitor a lot of ELP and CLN in real-time for application purposes."

"Centreon is a solution, and it is very good and efficient if you put all your infrastructure inside."

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

"What I like most about Centreon is that it is very flexible and customizable, based on the user and/or business needs."

"For servers and for applications, it was very, very efficient."

"It is decentralized, which is better, because you can reduce the load from a single system. Also, you get a better view because it's more independent. Then, for the management, it's nice because they have one central system. With that, they can manage all the other systems, as well. This means they don't have to configure each system by system. They can configure it from one single interface."

"This product provides comprehensive reporting for our top management."

More Centreon pros

"Being open source lets us customize it for our monitoring needs, saving us money."

"It's very easy to manage and monitor it."

"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."

Cons

"Improvements I would like to see include a discovery solution, better reports, and end-to-end monitoring."

"Sometimes, Centreon does not show the status of services as updated, which should be addressed."

"I would like to see an improvement of the communication with big data systems, because Centreon is a monitoring system. In our point of view, Centreon should be a part of a source for a big data system, not a big data system itself. So, it should be easier to add data from the Centreon system to a big data system. For example, it should be able to teach machine learning."

"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."

"Centreon supports officially 10,000 services per poller. That is not much for larger customers, because this limit is reached very quickly. We use it with three times the limit without any problems, but Centreon says, "Okay, we are only supporting it with 10,000 services." We are aware that increasing the limit has different impacts because they need to support it. However, for most customers, it would be be very good if they could increase the limit of services."

"This solution lacks service monitoring in the cloud."

"Centreon introduced network discovery in the most recent update. However, it doesn't work well. Our previous monitoring tool could discover networking equipment on the network and identify the relationships between the devices."

More Centreon cons

"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."

"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."

"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."

"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."

Pricing and Cost Advice

"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 pricing works out well for us, given our environment and where we are."

"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."

"I would like to see improvement in the licensing model. You can purchase X number of licenses, up to 1,000 devices or 1,000 instances. Your next batch is 2,000. But what if you only need, say, 1,200? The model could be changed a little bit."

"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."

"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 solution has a free part and after that threshold, you will need to pay. For example, if you believe you can create an interesting map, most of the time, you will have to pay 10,000 Euros per year for having access to these components."

"The pricing is quite reasonable, especially when compared to the broader market."
