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

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

"What I like most about Centreon is that it is very flexible and customizable, based on the user and/or business needs. Centreon is very flexible when it comes to monitoring parameters. We can use scripts found on the internet or scripts created by our infra/apps team. Also, the data visualization features are very simple and straightforward, yet very informative."

"What we like about it is that, whereas with Nagios, by design, if you have five or six data centers, you have to open five or six web pages to see what's going on, In Centreon, this is all included in one page, a single site, one dashboard. You don't have to jump from one specific dashboard to the other."

"It's the best tool on the market for that at the moment."

"The most valuable feature is the monitoring of servers and networks, because we have a lot of them and need to maintain control."

"It supports active monitoring so we don't have to use traps. From time to time traps are not very useful because we never know if they are actually working or not. The reporting part is also valuable as are the event logs. Using them we can check right away if something has had a hiccup."

"When we started to work with Centreon, there were about 30 people in our company and now there are 90 people, so our company has been growing and growing with Centreon."

"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."

More Centreon pros

"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."

"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."

"The API makes it pretty easy to integrate with any system."

"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 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."

"With limited hardware or a virtual machine, you can address a huge network, hundreds of thousands of elements that need to be monitored. Other commercial software is not on that level."

More OP5 Monitor pros

Cons

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

"I would like to see more plugins. That is something it needs. There is also room for improvement through dynamic thresholds, or self-discover thresholds. I would also like to see a discovery feature that could map the whole network environment and automatically suggest things."

"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."

"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."

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

"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."

"The reporting has room for improvement."

"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."

More Centreon cons

"We do not get performance reports properly, which needs improvement."

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

"They need to improve the dashboard interface."

"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."

"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."

"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."

Pricing and Cost Advice

"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."

"I think Centreon's pricing is fair, especially given the criticality of our system. They were cheaper than the other solutions. The licensing terms were pretty straightforward. I believe it was based on the number of hosts."

"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 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."

"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."

"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."

"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."

More Centreon pricing and cost advice

"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..."
