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

"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 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."

"I can't point to one valuable feature. All of Centreon is good."

"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."

"Centreon's real-time monitoring, despite having some manual aspects, supports us in managing our operations effectively."

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

"It provides visibility into the network."

More Centreon pros

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

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

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

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

Cons

"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."

"I think Centreon's security could be improved by leveraging AI. That's where things are heading in the industry."

"I would like them to improve their documentation. When I faced some issues, I was looking for more documentation on the Internet. There is official documentation on Centreon's website, which sometimes is useful. Sometimes it is not very useful, as you cannot find the information or enough examples of configuration. The answer for me was to contact the support, who helped me, but I was not able to find all the information by myself on Centreon's website. A Centreon community or blog would be helpful."

"Improvements are needed in the area of cloud monitoring, as that's a newer feature."

"There are times when we face issues with Centreon being in development mode. Sometimes we do not receive alerts, causing business impact, and users ask why no alerts were received."

"Release management and quality of testing need improvement, because with each major upgrade we have many issues coming in. Then, it takes several minor upgrades to get rid of them."

"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."

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

More Centreon cons

"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."

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

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

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

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 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."

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

"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 starts at around 5000 euro. However, this depends on: Your environment, the size of your host, how many hosts you have, how many remote pollers you have, and if you want to use the Monitoring Business Intelligence or Centreon MAP functionalities."

"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."

"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."

"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."

More Centreon pricing and cost advice

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