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

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

"Predetermined templates allow for simple and fast service monitoring configuration."

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

"E-mail alert notifications are valuable."

"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."

"It provides visibility into the network."

"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."

"We picked Centreon because, after an open-source comparison, and given what we want to do, and our skills and experience as well, it was the best solution for us, the most reliable for our services."

More Centreon pros

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

"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."

Cons

"The most important issue is the capability to interconnect with other systems."

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

"Sometimes, when the GUI and some of the search fields are being reset, and I return to the page, then I have to set them again. Therefore, some improvement on the UI and the filtering is needed."

"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."

"The product collects the information, but it fails to send them via SMS, WhatsApp or Telegram."

"Centreon needs to improve the granularity of the data as well as the graphical data. It would also be better to if there was improvement to the filtering/grouping system as well as the creation of views."

"The reporting has room for improvement."

"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."

More Centreon cons

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

"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."

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

Pricing and Cost Advice

"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."

"Open-source solutions like this can be very cost effective for an organization looking for a product that they can quickly implement, as there is no initial cost and there are no license renewal fees. However, it is important to take into consideration some of the related costs that may come along as needed, such as training, support, and product enhancements."

"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."

"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."

"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."

"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 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."

More Centreon pricing and cost advice

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