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.

Proactive monitoring has reduced network downtime and enables rapid incident response

The main benefits PRTG Enterprise Monitor provides for us include helping us respond quickly to network problems. For our virtualization switches, we normally use a different vendor, but I am not in charge of that particular system. I have not really used the pre-configured sensors feature in PRTG. A different team handles reporting. For now, nothing really comes to mind regarding additional functions for PRTG. I think it is good for what we use it for. I cannot really say much about technical support because I have never had a situation where I have to reach out. I would give PRTG Enterprise Monitor a final rating of eight. I would definitely recommend PRTG Enterprise Monitor to other users. I am an end user of the product. I am quite satisfied with the alerting part of PRTG, as it is quite good.

Quotes from Members

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

Pros

"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."

"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."

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

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

"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."

"The product is easy to use and you don't need to have any training. You can use it even if you don't have an IT background."

"The product is easy to understand."

"It can identify downtimes and disruptions."

"If an event is detected, such as a resource running low on storage or RAM, the product will notify you via email. Upon receiving the notification, action must be taken to address and resolve the issue. The feature I find most effective is its comprehensive nature. It's like having a permanent eye monitoring the network and all its nodes. Instead of manual monitoring, it detects anomalies automatically and alerts us accordingly."

"It provides a vast array of options for dashboard creation and monitoring of the activities within the environment."

"The solution's ability to monitor each and every aspect of our devices, such as memory utilization and port connectivity, is valuable."

"The product's most valuable feature is network analysis."

"What I really appreciate about PRTG Enterprise Monitor is that it is very easy to set up, especially the configuration, which is not complicated, and it is very straightforward to go in and change things."

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."

"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."

"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."

"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."

"There could be more security features included in PRTG Enterprise Monitor."

"When it comes to dashboard customization in PRTG Enterprise Monitor, there are not too many options, and I think that would not be a strong point for PRTG, but for our use cases, we do not really need that kind of customization."

"They should work on minimizing false positives by sending alerts promptly and confirming errors with minimal troubleshooting requirements."

"The solution could be improved by introducing security features similar to those available in Teams, as the current version only monitors devices and does not integrate IoT or OT devices."

"The solution could be improved by including a processing monitor, possibly with a language interface like Lua, allowing for writing custom sensors and processing outcomes of inputs."

"The solution could be improved by introducing security features similar to those available in Teams, as the current version only monitors devices and does not integrate IoT or OT devices."

"There is no unified monitoring in PRTG. It needs a lot of improvement in terms of integration."

"In my opinion, one area that could be improved in PRTG Enterprise Monitor is the capability to send SMS notifications. Notifications are crucial for alerting us to areas that require attention."

More PRTG Enterprise Monitor cons

Pricing and Cost Advice

"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..."

"PRTG Enterprise Monitor's pricing is reasonable."

"The pricing is $2,149 for software without maintenance, and licenses are sold in the minimum bundle of 500 interfaces."

"The solution is affordable."

"PRTG Enterprise Monitor is an expensive product."

"I rate the product's pricing an eight to seven out of ten."
