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

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

"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."

"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."

"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 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."

"PRTG Network Monitor is easy to set up. Within a few minutes, it is operational."

"PRTG gives us true visibility of the downtime of particular circuit functions. So if a circuit is up but not routing traffic, I will know with this tool. I can write a customized script for a sensor to detect specific things."

"I think net flow is PRTG's most valuable feature because it doesn't cost much for us because the net flow sensor is already included in the PRTG license. We can monitor our traffic in our proxy and router."

"It is easy to use and intuitive, which is really important. It does what it says on the box by giving you a visual of the state of what is going on at any one time."

"The most valuable features of PRTG Network Monitor are user-friendly, and the graphical interface is good for all the network devices that are mapped in this organization. It's very easy to find reports for any devices that we are looking for."

"PRTG has improved our visibility and response time to issues related to remote sites."

"From a network point of view, we can see the state of the network, as well as bandwidth usage and downtime."

"It is a central solution in terms of how to actually use it. It has a very easy dashboard. Everything is concise. We are able to create custom sensors. For different parts of the business, we have many products across many environments, and it works for everything."

More PRTG Network Monitor pros

Cons

"They need to improve the dashboard interface."

"We do not get performance reports properly."

"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."

"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."

"OP5 Monitor could include application monitoring in addition to infrastructure monitoring. If application business transactions were monitored, it would be helpful."

"Users need to buy the more expensive licenses if they expect to be able to scale."

"The dashboarding definitely needs improvement."

"Mostly, this software has sensors for devices to monitor specs and you can build or develop or modify various sensors, according to your company's needs. But you may need to do that with coding or plugins or with the support of Paessler AG, the manufacturer."

"The desktop app is the one area where it do with some improvement. From a user's perspective, I would like to be able to get more out of the desktop app as opposed to where we are now with it."

"Needs ability to monitor standard notification time (notify after X time)."

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

"PRTG Network Monitor should provide syslog monitoring since it is not available at this time."

"PRTG Network Monitor could improve by having a feature to allow uploading of preset standard network switch configurations and the ability to monitor the SLA configuration, such as uptime for the switches or internet connectivity. This would be very useful."

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..."

"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."

"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"

"While I am not the person who deals with pricing, I would say that we pay around 1000 pounds a year."

"The price is pretty comparable."

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

"We pay nothing for it. Its 100 sensors have allowed us to put a magnifying glass on some systems, providing an extra layer of detail. Therefore, our outgoing is nothing and our incoming is a lot of useful data that we can react to proactively."

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

"The ability to use the base version with 100 free sensors is great. The cost on other packages can be very reasonable."

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