Flexible device polling times and extensible modules are key features for me

There are lots of reasons why I'm using it. The installer itself is basically something that can be used as a no-questions-asked type of installer. I can use it with automation tools like Chef and Puppet. I don't have to answer some random questions. I can worry about all that stuff later on in the configuration. It allows for variable polling times of devices on the network. Because it's all in text, in general, that obviously makes it easier from the automation perspective as well, to modify configuration on the fly, using Puppet and those kind of tools. It does have different modules, so you can extend the solution as you need it, or get as little as you need in the beginning, so you don't have to buy a full set of modules. You just buy what you need and expand later on.

Alerting precision has reduced incident response times and improved department-level network visibility

The auto-pause sensor during the maintenance window is good without any false alerts, and it prevents me from getting flooded with alerts during planned maintenance, helping department heads understand their own network usage better. It has reduced incident response time by giving clearer ownership of each alert, ensuring alerts go to the proper recipient. SNMP testers and auto-pause are among the best features of PRTG Network Monitor, which is particularly useful for different departments such as HR and finance, where alerts can be filtered accordingly. The alerting features and dashboard of PRTG Network Monitor are very helpful, especially in our industry. However, the dashboard can look cluttered on smaller screens, which is one negative aspect. PRTG Network Monitor has impacted us positively; we have stopped getting flooded with alerts during planned maintenance or unplanned outages. Compared to others, this gives specific alerts very quickly and helps department heads understand their own network usage better, thus reducing incident response time so that each alert has clear ownership.

Quotes from Members

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

Pros

"The installer itself is basically something that can be used as a no-questions-asked type of installer. I can use it with automation tools like Chef and Puppet. I don't have to answer some random questions. I can worry about all that stuff later on in the configuration."

"The big thing is the event management engine, which is really, really nice to use, and it comes at a reasonable price, unlike some of the competitors like Netcool from IBM. Those kinds of tools are hugely expensive and they come as resource-heavy types of solutions. This obviously doesn't require as much hardware, but it does offer similar benefits where you can manage all the events."

"It does have different modules, so you can extend the solution as you need it, or get as little as you need in the beginning, so you don't have to buy a full set of modules. You just buy what you need and expand later on."

"In my case, I prefer to only poll interfaces that have descriptions, and the ones that don't have descriptions, I don't really want to know about them. It does allow for all these bits and pieces and adjustments, and fine tuning to get it to a point where it works for my needs."

"It allows for variable polling times of devices on the network. Because it's all in text, in general, that obviously makes it easier from the automation perspective as well, to modify configuration on the fly, using Puppet and those kind of tools."

"The scalability is good. You can improve a remote host or the clustering. This gives it the flexibility to monitor another infrastructure remotely."

"It is able to satisfy all our requirements in terms of email notifications and specific errors on the devices."

"PRTG Network Monitor helped prevent incidents by creating an alert to the DL when servers go down, notifying me before it became a bigger problem."

"The most valuable feature of this solution is being able to see things graphically."

"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 remote probe feature in PRTG Network Monitor helps you monitor remote systems or your network at a lower cost than other solutions."

"PRTG Network Monitor has positively impacted my organization as the hourly basis has been reduced, making a significant impact."

"One of its valuable features is the fact that it handles multiple operating systems... And I like the fact that it tells me when things are about to fall over, which means I can preempt it and not have to wake up at three in the morning to fix it."

Cons

"These kinds of solutions are more node- or device-based solutions. It would be nice in the future if they could be more data-oriented, so it would be easier for me to pull different stats based on ad-hoc requirements; but in a big, centralized database where I can pull specific things, and mix and match the way I want to."

"In a very few cases, customers want more detailed reports, which we cannot meet."

"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."

"I've encountered a challenge in my functions, particularly in adding and printing."

"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."

"The technical support service should be improved."

"PRTG Network Monitor can be improved as there is a lot of manual cleanup needed, which could be reduced."

"We need something that is more predictive. We would prefer if it wasn't a solution that was corrective and instead offered predictive insights so that we can handle problems before they even occur."

"The product could be improved by being cross-platform friendly."
