Useful online resources, customizable, and highly effective monitoring

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. If there are corrupt files the data can be extracted from them. Anyone who wants to see the performance of memory usage, such as whether it's at 80 to 90 percent, can use this tool. However, other tools can provide this information in two minutes, this tool is more time-consuming and the report it provides is not very effective for practical use. When it comes to reports, the tool falls short. During a recent call, it was noted that while the company has distributed servers across the globe, only the master server can accommodate the reports and events, causing delays. If other servers experience issues, the team cannot view the reporting or tag things, such as for troubleshooting purposes. If this aspect was improved it would be an excellent tool.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"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."

"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."

"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."

"We can also observe whatever we want, and there are no limitations."

"The email notifications are helpful, and the dashboards are user-friendly for people with little network monitoring knowledge."

"The most valuable feature of PRTG Network Monitor is its ease of use."

"It is a very stable solution. There are no bugs, glitches and we have not experienced any crashing."

"Network Discovery is a feature that our customers like a lot."

"The simplicity is what I appreciate about PRTG Network Monitor."

"The real-time monitoring and alerting are its most valuable features."

"I really love the activity library. It gives the flexibility to discover data and metrics about my interface and data server."

"There was only one feature I liked about PRTG Network Monitor a lot, and that was bandwidth monitoring, though, in the newer versions of the tool, that feature is now a bit lacking. Pricing for PRTG Network Monitor is also not as expensive. It's a good tool, even for beginners."

Cons

"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."

"We do not get performance reports properly."

"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 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."

"They need to improve the dashboard interface."

"They could improve the process of updating the license."

"With custom sensors, there is a lot of work which needs to be done in the background, just for it to be tailor-made for the specific thing that we are actually monitoring. We take a lot of time with the custom sensors. I would like to see the customer sensor be more robust and a bit more varied."

"PRTG Network Monitor should improve the NetFlow dashboard, there is no flexibility, and the NetFlow is not meeting the business needs. Additionally, they are missing part of the configuration management."

"I would like a more straightforward ability to create dashboards and maps. The network maps should be a bit more flexibility in the GUI to do what we need to do."

"I would like the ability to monitor Cisco IRS devices."

"When you email the support team, they take three to seven days to respond and resolve simple issues."

"PRTG Network Monitor can improve the reports. In the reports, you have to give an alert for that SMS and email, the emergency calls and downtimes have to be reported accordingly. You have to enable email services or an SMS gateway service to receive more alerts at the proper time."

"PRTG's documentation could be improved."

Pricing and Cost Advice

"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..."

"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."

"We pay for PRTG Network Monitor annually. The price is approximately 10,000 rupees annually."

"When you buy PRTG, everything comes in one bundle. Licensing is very easy."

"Licenses are very expensive, so I would like to see cheaper licensing."

"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."

"The licensing fees are billed annually and there are no costs in addition to this."

"We looked at PRTG and SolarWinds. From a cost side perspective, compared to PRTG, and from what you get back from it, PRTG was sort of a hands down the winner."

"I rate the price of PRTG Network Monitor an eight on a scale of one to ten, where one is a high price, and ten is a low price."

"On a yearly basis, I believe it's between £1,200 and £1,500."
