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.

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

"If they have the same issues that we had, which means a lot of pollers spread across the whole infrastructure and no central view to look at the entire status with the need to manage everything together, then it is a good solution."
"During the day it probably saves us 50 percent of our time, and during the night it's even more."
"The most valuable feature of the solution is that most of its plug-ins are free."
"It provides visibility into the network."
"What I like most about Centreon is that it is very flexible and customizable, based on the user and/or business needs."
"The most valuable feature is that we can manually configure everything we need. After it comes inside the interface of Centreon, you can display it. Because the interface is quite user-friendly, you can manually configure the configuration very deeply, which is very pleasant and useful because you can monitor and see everything on your service list, dashboard, or MAP. The most useful feature for me is that you can create your own plugin and monitoring query."
"Once everything is set up correctly, it reduces our MTTR by 50 percent."
"We are alerted on service impacts and not when something is down. We have saved a lot of time on non-business-hours intervention."
"Especially with the API, where I can use the data with many other systems, it's great."
"Its open-source environment is accessible to everyone."
"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."
"Instead of checking the logs each Monday, or checking that applications are running, and checking your ticketing system for angry users, you put this system in place and it monitors and continuously tests everything that is of importance to you and your users."
"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."
"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."
"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."
"We can also observe whatever we want, and there are no limitations."
 

Cons

"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."
"Centreon is actually missing an easy way to create a trendline for the metrics. Actually it is possible to create it, but you need a good knowledge of math, Centreon, and RRD."
"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."
"Now that we got it, I haven't had time to work on it since it is a paid solution that is quite expensive."
"I think Centreon's security could be improved by leveraging AI. That's where things are heading in the industry."
"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."
"The problem with the reporting is you have to configure the report, and after that, you will have the same report every month, every week, every day. You have to sync it in order to have a great report."
"We do not get performance reports properly, which needs improvement."
"They need to improve the dashboard interface."
"The user interface is not what we are used to these days, and should be improved."
"The solution is useful for tweaking. However, there have been some negative experiences, such as limited report capabilities. The only report available is in PDF format, making it difficult for teams managing multiple servers to extract data in Excel format. The speaker recommends that the team improve the report capabilities to better serve users."
"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."
"OP5 Monitor could include application monitoring in addition to infrastructure monitoring. If application business transactions were monitored, it would be helpful."
"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."
 

Pricing and Cost Advice

"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."
"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."
"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."
"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."
"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."
"It's quite expensive when you use the Enterprise version, but if you compare it to other providers, it's more like a middle-of-the-line product. It's always good to have a price that is lower, but I would say the price is okay because we get very good support and if we have any other issues we can always contact them. There has never been a time when I didn't get help from them."
"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."
"The solution is very effective, despite the low price."
"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."
"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..."
