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

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

"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."

"Its open-source environment is accessible to everyone."

"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."

"The best feature is that it is very relatable, stable, and scalable."

"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."

"Instead of checking the logs each Monday, or checking that applications are running, and checking your ticketing system for angry users, you put this system in place and it monitors and continuously tests everything that is of importance to you and your users."

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

More OP5 Monitor pros

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

"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."

"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 solution offers perfect real-time bandwidth monitoring and SNMP functionality."

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

"The product is easy to understand."

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

"PRTG is good and very easy to use."

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."

"We do not get performance reports properly."

"We do not get performance reports properly, which needs improvement."

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

"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."

"They need to improve the dashboard interface."

More OP5 Monitor cons

"PRTG Enterprise Monitor should include more functionalities and features that are similar to SolarWinds."

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

"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."

"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 licensing policy needs to change. The current model requires customers to purchase a minimum of two thousand licenses, which is not flexible for all customers."

"The support must be improved."

More PRTG Enterprise Monitor cons

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."

"PRTG Enterprise Monitor is an expensive product."

"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's pricing is reasonable."

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