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

"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."

"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 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."

"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."

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

"The feature I like is that it can easily do a lot of mapping."

"PRTG is integrated on Windows."

"Stable and scalable network monitoring tool. Installation is simple and straightforward."

"My opinion is that this solution is not very expensive."

"We like the alerting system, the SNMP monitoring and the customization of the bandwidth."

"Stability-wise, I rate the solution a ten out of ten."

"We use the remote probes a lot for our branch offices. Instead of deploying the full instance of PRTG, we'll put a remote probe out there. This simplifies the whole deployment for us."

"The solution provides us with needed feedback on our IT infrastructure. It gives us really good quality of service when it comes to monitoring of available space and available resources. It allows us to preempt issues before they become a problem for the business."

Cons

"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."

"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."

"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."

"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."

"PRTG's documentation could be improved."

"The only sort of limitation is the actual probes. So, if you don't have enough probes on there, you can over flip them and cause the WMI sensors and SNMP sensors to sort of overload. Sometimes, they might timeout for a minute, but they do come back."

"The technical support could respond a little bit quicker."

"Integration into service management ticketing systems could be better. They should simplify the integration into big service management platforms like ServiceNow, Remedy, and Cherwell. They're really into monitoring, but they don't do any self-resolution. It would be better if the company moved more into the AIOps space so that you could actually kick off some remedies. I know that you can execute some commands from the tool, but you need to develop those all yourself. It would be really handy if they had some auto-remedy scripts that they could develop on top."

"The solution could be better and faster when it comes to performance."

"They just released a newer version of the desktop app, a beta version, that I have been trialing out. I prefer the older version, only because of how the layout is designed"

"If PRTG could help me see the bandwidth for each host I have on my network, either for a wireless or a wired network, that would be very helpful."

"I would like to see Office 365 monitoring. Essentially, it doesn't do it. I assumed not at all, but apparently it does it slightly. However, due to issues with APIs, they currently don't provide full monitoring for O365."

Pricing and Cost Advice

"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."

"The price of PRTG is reasonable. PRTG's competitors like SolarWinds and ManageEngine charge more for the same functionality."

"Our licensing costs are 10,000 euros over three years."

"The pricing for PRTG in our case is reasonable because we have a lot of applications to monitor within PRTG. It is not that expensive."

"All monitoring system is close to the same pricing scheme."

"We have unlimited devices and sensors, and it is a bit pricey, but we do have unlimited sensors. With all things considered the price is fine, related to the solution itself. PRTG Network Monitor is good value for money."

"At the moment I'm only using 500 sensors. I pay yearly, so it's a cost that's easily swallowed."

"We pay for a perpetual license and we have a support fee."

"It's an annual license that is based on the number of endpoints that we're tracking and using."
