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

"The customizable reports and dashboards are really flexible. We started this partnership with Centreon, when we were looking for a solution, because of the flexibility of the reporting. That's what we found to be most attractive in the solution. You can display the data as you want."
"It's the best tool on the market for that at the moment."
"Centreon's most valuable feature is Opsgenie."
"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."
"We and our customers have saved so much time that we are acting instead of reacting to a situation in a positive way."
"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."
"I really like the filtering capabilities of it. You can easily tell what's critical next to what's okay, the state of the services. It's very easy to get the whole picture quickly."
"During the day it probably saves us 50 percent of our time, and during the night it's even more."
"We can also observe whatever we want, and there are no limitations."
"Its open-source environment is accessible to everyone."
"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."
"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."
"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."
"Especially with the API, where I can use the data with many other systems, it's great."
"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."
 

Cons

"It is necessary to improve service monitoring of database services in the free version."
"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."
"The most important issue is the capability to interconnect with other systems. It already exists for some of them. For example, the Stream Connector is something we use to populate data in another system. This kind of facility for connecting should exist for all products that it makes sense to have connected to a monitoring solution."
"The reporting has room for improvement."
"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."
"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."
"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."
"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."
"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."
"The user interface is not what we are used to these days, and should be improved."
"They need to improve the dashboard interface."
"OP5 Monitor could include application monitoring in addition to infrastructure monitoring. If application business transactions were monitored, it would be helpful."
"We do not get performance reports properly, which needs improvement."
"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."
"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

"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."
"It is perfect and very cheap if you are a little company or startup. After that, it is quite expensive for a big company."
"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."
"The pricing works out well for us, given our environment and where we are."
"The pricing is acceptable."
"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."
"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..."
"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."
