Easy to set up with good documentation and helpful support
I'm using it for a customer The packet flow switch is the most valuable aspect of the solution.  It's an easy product to set up. We can scale the solution if we need to. It's stable.  The documentation is well-written and quite useful. It's compatible with other products.  Under the pocket flow…

Has reduced troubleshooting time and improved issue detection through sensor alerts and team collaboration
PRTG Network Monitor can be improved because the dashboard themes feel outdated. It should be updated to a newer version for the new Gen Z customers. The notification sound options are limited unless customized. Restarting probes after Windows updates is necessary, and there should be some kind of automatic restart. The initial auto-discovery added too many unnecessary sensors, so auto-discovery should only take the necessary sensors into consideration.

Quotes from Members

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

Pros

"An issue that used to take days is now fixed within minutes to an hour."
"I love the single pane of glass view. It makes it easier to not have to navigate everywhere. It allows more simplistic visibility, without having to go from tool to tool to tool, or from window to window to window."
"It has cut our group's troubleshooting time down significantly, e.g., depending on the issue, what would normally take maybe a couple of hours will now take minutes."
"We are attracting customers in good sized numbers as we advertise and market this solution."
"From a troubleshooting perspective, it allows us to quickly search all data TAP points in the network and helps our network engineers get to root cause quickly."
"The tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."
"It's an easy product to set up."
"We use it for monitoring whenever we update a new circuit or site."
"Ease of set-up – it is quick and easy to add a probe and start collecting data from a device."
"Accessibility, ease of use (Web GUI, MobileApps). In general, compared with other software"
"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."
"I would recommend this solution because it's great for monitoring network traffic and producing reports."
"We have been extremely satisfied with PRTG's capabilities overall."
"The sensors and remote probes are phenomenal. We use them for all of our global sites. The problem with our global sites are that they are all VPNs. If the link goes down, you can't monitor other solutions, as it just goes off the grid. Having remote probes allows them to still carry on and get the information that we need when it comes back up, sending the information to us."
"The solution is very easy to use and the web provides information with ease."
"It helps the entire organization become digitally enabled."
 

Cons

"We don't use the single pane of glass view, even though we own it."
"The scalability has some limitations and quirks to it. I would like to be able to upgrade rather than replace the whole thing."
"I'd like them to make the product more user-friendly."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM. I don't like when devices go end-of-life on us so quickly. If we can get more of an advanced notice of when an end-of-life is brought up, because our certification process within the organization takes a while."
"There is a timeout feature that we have been asking for awhile."
"It's not able to communicate with our probes."
"The solution is not great, but it is not bad."
"I would like to see an improved level of stitching between IPs."
"There seems to be a big jump from the basic scan to the really thorough scan. There is a big jump in the quantity of sensors it uses for certain things. One minute you might get ten and then the next you get 200. There seems to be a big jump between the two at times."
"Sometimes the error messages are too vague and don't directly tell me what went wrong."
"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 icons on PRTG's network diagram are hard to find. For example, finding the icons for firewalls and servers is difficult, so we're struggling to create the network topology."
"Dashboards can look cluttered on smaller screens, and the UI can feel crowded when there are hundreds of sensors in one group."
"There are some vendor-specific sensors in PRTG Network Monitor, particularly for older hardware, that don't always provide consistent results."
"I'd like to see the inventory of the device improved."
"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."
 

Pricing and Cost Advice

"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
"I would like it to be more scalable with less spend."
"This product could be cheaper."
"The price is a little high."
"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
"The price of PRTG Network Monitor is reasonable for the features that the solution provides. They charge you per monitoring, not per node, it is per port that you need for a device."
"The price of PRTG Network Monitor is reasonable."
"It's a cost-efficient tool."
"We've got 1,000 nodes and I believe it's a few hundred quid a month."
"While I am not the person who deals with pricing, I would say that we pay around 1000 pounds a year."
"The price is actually on the cheaper side. If you're going with the unlimited license code, it's very cheap compared to competitors unless you're going for something free, like Zabbix. But you get what you pay for, and it doesn't have the full suite of products or tools like SolarWinds or a ScienceLogic."
"The licensing fees are billed annually and there are no costs in addition to this."
"The price was pretty good, very competitive."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
