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

"Flowmon is more easy to understand and helps find network issues more quickly."
"Flowmon is more easy to understand and helps find network issues more quickly."
"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"The solution is stable."
"It is an open platform, so in terms of integration, we are quite happy. We can integrate it with other SNMP solutions. We can also integrate it with security solutions, such as a SIEM solution."
"We can also observe whatever we want, and there are no limitations."
"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."
"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."
"The API makes it pretty easy to integrate with any system."
"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."
"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."
 

Cons

"I do not know the detailed pricing."
"It would be helpful to have more details about the monitoring of the infrastructure. It should have support for SNMP. This is something that is currently not there in the product."
"The licensing price could be better."
"If there was better visualization in Flowmon Solution it would be good."
"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."
"We do not get performance reports properly."
"They need to improve the dashboard interface."
"The user interface is not what we are used to these days, and should be improved."
"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."
 

Pricing and Cost Advice

"The licensing fee accrues only once, but that of support is annual."
"The price of the solution could be better."
"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"OP5 has a very low price as a solution, compared to many other solutions out there."
"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."
"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..."
