Features: Icinga offers a modular architecture for seamless integration with plugins, robust alerting capabilities, and customization options. OP5 Monitor provides extensive network performance monitoring tools, advanced reporting, and detailed system performance visualization.

Room for Improvement: Icinga could improve its user interface, enhance out-of-the-box functionality, and provide better documentation for advanced features.

Easy to use, and it's possible to customize the product as per the needs we may have but average multi-tenancy aspect

It's supported by the community. We use Icinga, which is not part of the Open-Source platform but is wrapped into a commercial solution from another provider, a local provider in Italy. Icinga is an open-source platform, so it is supported by the community. It's quite easy to use, and it's possible to customize the product as per the needs we may have. So it's not expensive, and it's quite a general purpose. We can easily monitor any kind of infrastructure we encounter. The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated. The alerting is the same as any other monitoring platform. It's not a "wow" feature that has changed our lives, but it's perfectly adequate.

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

"I like the ability to amend and adjust things really easily, which is useful in a case where you could make it auto-discover and then set a template to say all of these applications or servers under this template have an automatic threshold set that you’d set up manually."

"The most valuable feature is one that not many are even aware of, as Icinga has a self-healing event handler where if the service is down, it is automatically restarted, and you can configure the handler to take action after the critical alarm without human interaction."

"The apply rules feature saves a lot of time."

"Macros and the ability to connect it to Google Maps are valuable features."

"I use it for monitoring infrastructure and it was very good for that issue."

"If you have a small infrastructure or a small number of devices that you want to monitor, then I think it's a good solution."

"People should know that it is simple and advanced."

"Icinga has multiple automation and integration features. There is an API for everything and a web UI for configurations. The APIs enable you to automate tasks in Icinga. We can also use plugins to talk to the API. The Icinga Director talks to a database in the background, and you can import settings from the CMDB to all systems in Icinga."

More Icinga pros

"Its open-source environment is accessible to everyone."

"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."

"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."

"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."

"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 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."

More OP5 Monitor pros

Cons

"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."

"Icinga’s automation could be improved."

"One of the areas that are frustrating is remote monitoring for more than one machine."

"It is not really adequate for our current needs. It causes additional issues which we have to work around and takes us time that a better solution would not."

"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."

"Icinga is a complex solution that's hard to learn. It's a powerful product for monitoring, but new users will have a hard time figuring out what to do."

"We have found some problems with Nagios, and support isn't very responsive."

"Network Discovery capabilities would be extremely helpful."

More Icinga cons

"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."

"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."

"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."

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

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

"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."

Pricing and Cost Advice

"The solution is free to use."

"The product is inexpensive compared to other DBM products."

"The solution is cheap."

"It's an open-source solution."

"This is an open-source solution with paid support."

"We're using the free version of Icinga."

"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."

"It is cost-effective, and the return on investment can be very interesting because the price is low."

"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..."
