PRTG Network Monitor Reviews

PRTG is a very versatile and flexible tool. We have a vast number of users spread over more than 300 installations in India and neighboring countries. We have many different types of customers who use this tool for project control monitoring and other types of network monitoring.

PRTG Enterprise Monitor comes with built-in analytics capability. This means that if there is an incident, it not only tells you that there is an incident, it will also tell you the root cause.  For large networks, this is beneficial as the network team can easily home onto the problem directly without spending time searching for the root cause, which allows them to attend to the problem as the alerts come in. 

Having an Alliance program is very valuable. The Paessler Uptime Alliance Program focuses on making the core network product, which is PRTG, progressively better. It also combines capabilities from any partners in the ecosystem. For example, we have UVexplorer (a US-based company), taking care of network discovery, network topology mapping, and network asset mapping and we have other partners, like CORP-IT, that provide us with the plug-in to monitor SAP and sensors. In other words, it's an ever-expanding network management system.

If you can get everything into a particular environment, you can monitor your factory automation systems; however, they also need to be monitored for maintenance purposes. If you intend to automate factory information, you cannot afford to fail. Monitoring the equipment and receiving dashboard alerts for maintenance is highly advantageous. This is a great feature of PRTG. Currently, we are competing in the market with SolarWinds and ManageEngine. They are good, but we come out winning.

From a security perspective, PRTG provides you complete Secure Socket Layer-based access. If you're monitoring your network or a private network using a BLS cloud, security is automatically ensured because of the way you're deployed.

I don't believe there is much need for improvement. The product is constantly improving. I used to think that the reporting could be quicker, but presently, there is a solution for that, thanks to the SLA plug-in from CORP-IT. The basic reason why PRTG reportings were slow is due to the fact that the reporting engine is built-in as a functionality in the PRTG application. The application does a lot of things, like monitoring and managing the database and it updates your dashboard in real-time.

The last priority goes to the reports. Typically, reporting can wait if there are demands on other aspects of the product, but because of this, the reporting was becoming too slow because it was always the last priority. I used to think that needed to be improved but the formal plug-in has solved this issue. Some customers don't mind the slow reporting, as not everything is urgent. However, if you want faster reporting, the options are available. 

Maybe in the future there will be room for improvement, but currently, there is nothing pressing that I can think of. 

I have been using this solution since 2003. Previously, I used CA, IBM Tivoli, BMC Patrol, and HP OpenView. 

I have not come across any situation which was so bad that PRTG has crashed.  

The stability and security of this solution are intertwined. PRTG is not static, it's always evolving and updating. Basically, the security situation at any given time makes PRTG's functionality vulnerable. Thankfully, they take this as a top priority, providing new solutions all the time. Paessler releases 7 to 8 updates a year to combat this issue. Because of this, I would say we're in lockstep with our security needs which also tie into the stability of the solution.

Presently, PRTG is extremely scalable. In fact, I would boldly say that this is the most scalable network monitoring tool that I know of. 

If you have PRTG on a single server, the server can perform many functions. PRTG has a local probe that probes according to the configuration settings; however, even the best servers cannot take on an infinite load. Thankfully, PRTG offers a remote probe as part of their license return. This has multiple advantages including lessening the load of the server.
For example, should the communication link between the remote probe and PRTG server break down, the local probe will keep on accumulating data locally. When the link to the server is established, all the collected data is then flushed into the core. That is one way of scaling, but keep in mind, that adding multiple remote probes will eventually saturate the core because now you have to manage the data from so many sensors.

 Depending on the types of sensors and monitoring frequency, as your network expands, you can keep adding PRTG digit codes. You can keep adding servers and sensors to focus on monitoring. In my opinion, I don't know of another product where you can do this. Even if you've applied PRTG on multiple servers, you can still manage all of them using a single dashboard.

The initial setup was very easy. What you pay for this product encompasses everything. When we sell this product to a customer, we say "You can do it yourself, you don't need to pay for installation". So far, at least 70% of our customers are able to manage and there are some that don't need our help at all; however, there are occasionally a few customers who email or call us looking for support, in which case, we are always quick to help at no charge. This is all included in the price you pay for this solution. There are no hidden costs and the customers appreciate this.

Downloading and installation take less than five minutes, but after downloading, there is configuration to be done. Installing the software is only one part, about 30 to 35% of the whole picture. Our networking team needs to be organized because this is how we guide our customers in the right direction before the product arrives, which saves them a lot of time. We have a network team, server team, and a storage team. They are very structured and know how to do their job well — they can install some of the largest networks in just three to four hours. In the best-case scenario, it would take them less than a week to install PRTG Excel.

We encourage our customers to use the trial version first, to build a rating. By doing so, when they are ready to purchase the full commercial license, they will be ready to be productive from day one. 

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

PRTG is available as a service network monitoring service in the cloud, with the option of purchasing up to 1000 sensors. For small companies, it's more of a network tool because smaller organizations like to focus on their code builders. Smaller companies cannot afford or attract very technical people to monitor the network with cloud hosting. PRTG can fix that, but it's only good for small workloads.

The process of network management itself has to be organized. You have to organize yourselves in terms of how your network is structured: how do you want to monitor and manage it? Even that has to be organized as well. For example, if there is a problem with the database, PRTG should be able to alert the data administrators, not anybody else. Only they should take care of any pressing issues; if they don't, the method will go to the wrong person, which can be very damaging. There is a lot of human organization required in administering a method between technologies and that needs to be organized well for the network monitoring process to be effective.

Overall, on a scale from one to ten, I would give this solution a rating of nine because everything has room for improvement. 

We use it to monitor services, things like hardware usage and whether hard drive space is running out. We use it for quite a lot of our networking solution as well. If there's a glitch in the network, anything that's abnormal, being able to see that show up is quite good.

The historical data provided by the solution helps optimize our network performance. We can see what's going on in our network infrastructure, more so in terms of our core networking. We can see which fiber links have been used heavily and, if they are used heavily, we can introduce more links to particular buildings or particular areas. It's more around the networking that we use the historical data. 

Also, if we have any issues with particular hardware, we can monitor those. We can monitor the network on those ports and come back with any issues or see if anything is flipping out or has stopped working. It's helpful being able to see that historical data.

It makes us more proactive, as opposed to reactive, with any issues. We tend to see issues occur before anyone else even knows about them. That's really useful for us. Particularly if there's any abnormality on the network, because of the historical data, we tend to know about it. PRTG tells us about anything that's out of the ordinary, which is good.

The sensors work well.

The remote probes seem to be a little bit buggy at times. They just stop working or they say they can't communicate. What we tend to do to is install the remote app onto the servers that we use. That seems to clear it up. As long as the app is there, all the probes seem to work fine.

It would be nice if, for the maps view - what you can lay out on the screens - there were a bit more functionality. It would help to be able to add titles to the top or to be able to change text sizes. There's not much you can really do with that in terms of configuration at the moment.

The stability has been good since it went in. It's never had any issues. It has just worked. It updates itself, it's easy to manage, easy to maintain.

It's difficult for me to judge the scalability. For what we use it for - I think we've got 1,000 sensors and we use about 800 or 900 at the moment - it all runs fine. I'm sure it would scale very well if we needed it to go any further than that. But for what we use it for, it's relatively small.

We haven't used the tech support or the online resources. It has always just worked; it's always been fine.

We have a third-party we go to if we get stuck with our network and they recommended PRTG. They actually started using it to troubleshoot some issues on our site, and from that, we decided it was something we wanted, so we invested in it from that point and set it up from scratch.

There wasn't really any system downtime which factored into our decision, but there were a few performance issues which PRTG helped us to solve. That was another reason to get it put in place, long-term.

The initial setup was surprisingly easy, the way the menus are all laid out. I set it up myself and it explained what to do, where to go. There were little pop-ups on the screen saying, "This is where to go for this, that's where to go for that." It made it all really easy to do. 

Also, adding servers or switches, it was auto-discovery, so I didn't have to do any config on that. You could just let it discover everything and then delete what you don't want.

It took about two days from the time I set up the solution until it provided feedback on our IT infrastructure.

PRTG was recommended to us and we went with it on the free basis to start with and then we moved to the paid version, for more sensors. We haven't really compared it to anything else, because it was recommended. Overall it seems very good.

Just install it, follow the instructions, and off you go. It just seems to work.

We do use the Desktop app and it's good, it works very well. It's very similar to the web-based system. It gets a little bit annoying sometimes because there are quite a lot of pop-ups. I'm sure we could turn them off but that's not something we've looked into. I actually find myself exiting the Desktop app, just to stop the pop-ups.

I wouldn't say that it has made our IT department more cost-effective at this point because, although we pay for it and we use it, we haven't really made any changes on the network because of PRTG. I don't think we've had any cost savings anywhere.

I would rate it eight out of ten. The desktop app seems a little clunky sometimes. There are a lot of pop-ups saying things are offline when they're not necessarily. That's more due to those probes. When we install the app on the servers there're no issues there, so we can get around that.

We use it for network monitoring, mostly. We look at any metrics that the sensors pull back for us, such as availability, performance. We have some custom sensors for service monitoring.

The solution's historical data helps us optimize network performance. We can find issues by looking at historical data and benchmark it against what it should be.

It's given us metrics which we can then pass on to customers, availability statistics and things like that. It's really added value to the services we provide. From that point of view, it has definitely improved things.

It makes our IT department more cost-effective because we can detect failures faster, we can do something about them. We can get early warnings on things that are going to go wrong, be proactive about dealing with them, and have less downtime.

It gives us the needed feedback on our IT infrastructure, such as utilization of disks on a server. We get that information back and are able to act on it.

One of the valuable features is the diversity of metrics available to us to monitor. It's all there, it's all in the box. It's all made very easy, by virtue of it being pre-configured. You point it at the box, pull your credentials in if you need to, and off it goes and does it. A lot of solutions do that, but this just has it all in one box, which is what makes it really good.

The solution’s sensors and remote probes are great, spot on. They keep improving them. It's only a problem from time to time when old sensors get deprecated and you have to replace them with a new one, but other than that it's a very good selection.

The overall feature set is good. It's diverse, it's all there.

I don't think the Desktop app is that great. I don't like it. I would like to see cross-compatibility on different platforms. Also, the window management isn't that great, and the refresh rates aren't that great.

Their roadmap is good and the features that they're releasing are good, but our main ask is around the scalability issue that I've mentioned elsewhere in this review.

If you have enough resources the stability is fine, fairly rock-solid. We're at double the recommended capacity in terms of sensors for our instance, and it's running fine.

Scalability is the only major sticking point for me. There is a recommended number of sensors, which is around 10,000, and we're double that. We're not comfortable putting any more than that, even though the server might be able to handle it. It's already well outside the support boundaries for the solution. 

The only option we have to scale is to buy another core, which would be a separate, stand-alone instance, would not be managed through the same interface, and we would have to be looking in two different places. We love the product, but at the moment that is the main sticking point for us.

There have been no real problems with tech support. We don't really need to go to them, the product takes care of itself. When we have needed them, they have been very responsive and gotten back to us quickly.

We did have system downtown before implementing the solution, but it didn't really influence our decision to get PRTG. We needed a monitoring system anyway, by virtue of the nature of our business.

We would have been using an open-source solution before PRTG but we needed a more feature-rich product to work with, given the number of solutions we were operating.

The initial setup was very easy. There's nothing much to do, honestly. You just install the software on the core server and then you can install remote probes in any private sub-nets that you need and they will speak back to the core. It's very straightforward.

Within about a half an hour of installing it, we had information back.

We did it ourselves.

Subjectively, it probably has saved our organization money, but it would be difficult to quantify it.

We pay for a perpetual license and we have a support fee.

We've had PRTG in place for a number of years, so what we evaluated was in the early days, a lot of open-source solutions: Zabbix, Nagios, Cacti, etc. PRTG is differentiated because it caters to all platforms and endpoints, has features for Windows, and WMI sensors which aren't necessarily available out-of-the-box in the other solutions. That would have been a determining factor.

It will do the job, more than anything I can think of. It will give you really useful monitoring statistics out-of-the-box, and will give you the ability to customize and do things that aren't there by default. It will take care of all your monitoring needs, pretty much, but just be conscious of scale.

I would say PRTG is an eight out of ten. We're very happy with the functionality. Those missing two points come from the scalability issues.

• Monitoring network
• Uptime
• Resources on servers
• Better monitor our network, local, and remote hosts, and network usage as well.

• PRTG has improved our visibility and response time to issues related to remote sites. 
• Nice product with an easy interface to use and a large variety of sensors.

• Ping monitoring
• WMI for RAM
• Hard drive space on servers
• Monitors site uptime (and notices when it is down), along with thresholds when server RAM or HD is running low, which has helped us.

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

Web-based interface is easy to use, but it is cumbersome to make changes across several devices.

No issues.

No issues.

Tech support and sales have been great.

Setup was straightforward. It is too easy to use up sensors on fluff items (core switch, etc.).  Took effort to focus on key items, such as uptime, etc.

Did not use the vendor to setup.

Currently, we are using the free version. ROI was immediate after receiving notifications with low HD or RAM on servers.

Sensors on free version can run out quick. However, the ability to use the base version with 100 free sensors is great. The cost on other packages can be very reasonable.

It was recommended by our network engineers. Other clients use PRTG and have had a great experiences with it.

It is a good solution. We are evaluating the advanced features and client PC application monitoring.

We use it specifically for our network devices and service providers. We're able to know if the connection with a certain internet service provider is still alive.

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

I would like to have a VM version that can be installed on a cloud such as Azure. We're using Azure, and we're eliminating on-premise servers. It would be helpful to have a PRTG version that can be installed on the Azure cloud.

I have been using this solution for five to six months.

It is stable. So far, we didn't have any problem with the product.

We're using the free version, and we can only enroll up to 100 sensors. 

Currently, we have two system administrators who use this solution.

We didn't use their support. We're using the free version.

We were using SolarWinds. SolarWinds is much more expensive than PRTG.

For those who have no experience with PRTG, it would be quite complex. Luckily, we have an experienced and knowledgeable staff. Our team did not encounter any problems. The whole set up took two to four days.

We set it up ourselves. We had two system administrators for its deployment.

We are using the basic PRTG that we can download for free. For now, we only need to monitor less than 100 devices. For more than 100 devices, we would need to buy a license. PRTG is much cheaper than SolarWinds.

I would definitely recommend this solution. I have friends in other companies who are also using PRTG, and their feedback is also good.

I would rate PRTG Network Monitor an eight out of ten. We're happy with the results.

Monitoring of all our disparate sites through a central console is our primary use case.

The historical data provided by the solution helps to optimize network performance because it gives us trends. We can look at what we're using, what our peaks are, what our lows are, to know if we can downsize our links or if we need to scale-up in the future. It gives us really good forecasting.

In addition, with the solution we're proactive now, we're not reactive. We used to wait for the users to call us with an issue. Now we have complete warning thresholds so we can fix issues before they become issues. Our users perceive it as our being able to provide a very high level of service because we're avoiding situations where they suffer downtime. It's definitely made our infrastructure more reliable from a user's perspective.

It also enables our IT department to be more cost-effective because we're not doing as much hands-on monitoring. We're able to let the system monitor things for us so we can focus on other things. We're getting more value out of our techies.

Finally, it provides us with needed feedback on our IT infrastructure. We can look at individual devices or solutions and see if we're getting throughput, and how to utilize the hours. And that informs our buying decisions. It gives us a perspective from every angle.

Speed of deployment is one of the most valuable features. It's really quick to install. You can also scan whole subnets or different networks and it comes back with a full scan of what you've got on your network.

It allows you to do different verticals. There are different ways you can monitor things with custom sensor probes. It's really adaptable to your environment.

The solutions sensors and remote probes are very good, quite thorough.

My overall impression of the solution's feature set is that it's a great product, especially the mobile app. I'm on call and I get push notifications, so it gives me a heads-up before there are any issues that get reported to me by users. It's all good.

The Desktop app is good but it can be really sluggish at times, especially when you're editing different elements. If they could speed up the way you maneuver around different OUs that would be really good. The map creator is quick blocky. It's not very user-friendly.

Also, when doing an auto-discovery, I wish that there were an approval stage. If you pick "full detail scan", it comes back with everything, and then you have to go back and delete them bit by bit. If there were an approval saying, "These are ones that are available," you just go click, click, click and be done. That would be great.

It's rock solid. We've had zero downtime with PRTG.

It's hard for me to talk about its scalability. We've got the basics, the 2,500 sensors, and that's what we use. It's fine. It has grown with our business but we've only grown marginally.

We haven't had to use technical support.

We previously used various open-source options like Nagios. They were quite limited and required specific agents being installed on all the hosts. They were slow to roll out. PRTG was a completely different ballgame. It was click and go. It was great.

The setup was super-easy. It was a simple click-and-go install, give it your basic SNMP strings and your subnet ranges, and away it goes. It took less than an hour from the time I set up the solution until it provided feedback on the IT infrastructure. It's really quick.

I did the deployment myself.

It's hard to answer definitively, but I would say it has saved money because it has avoided system downtime by enabling us to be proactive.

We had previous experience with things like HP OpenView, but it's been many years now. Our experience with it was that it was quite sluggish, very expensive. PRTG seemed to be at a very attractive price point, and its speed and the reviews we'd seen about it were really compelling.

Give the demo a go. You'll find it super-quick and you'll love the benefits of it.

I would rate the solution a ten out of ten. It's super-easy and cost-effective.

Previous solutions had to many dependencies and were unstable for the most part. Overhead and additional cost of critical features were costly.

Initial setup is as easy as it will get for a software of this type. The entire application core and probe literally install and run in less than 5 minutes. I am used to having dependencies and multiple modules taking over an hour to fully install for similar product.

SolarWinds, WhatsUp, OpenNMS, Nagios, Netcool, OPManager, Splunk

This is a review of PRTG version 14. As far as network monitoring and analysis, I cannot think of a more intuitive and flexible product on the market today. Where PRTG shines is in its speed and compact design. The latest interface is ideal for complex networks and as useful for simple networks. Initially, I had a negative reaction to the idea of the sensor based license approach. Once I deployed PRTG on the network, the sensor model makes perfect sense. For the amount of sensors that I used and the included features, the cost of PRTG is over 80% lower than other software suites that claim to have similar features. I am not an employee of PRTG, I am just a very satisfied user. If you are a sysadmin or netadmin and have been struggling to find the ideal monitoring tool, I urge you to give PRTG a try. The trial is free. You will not regret it. I just wish someone had told me about this application a few years ago.

My primary use case for the PRTG solution is network device monitoring. For example, if one of my Ubiquity access points goes down, PRTG will send an alert so that I can go and try to restart it and bring it back up before people start complaining.

This product can be improved by updating the net flow interface. The one that is in place works – I can get all the information I need from it – but it is a little bit clunky.

I have not had any problems with the stability of this solution. I have to reboot it once a year, which is a chance for me to do the updates anyway.

The scalability of this solution has gone smoothly for me so far. I am mostly using it just for pings, and because I don't have a ton of net flows going into it, I am not heavily taxing it. We have a couple of thousand devices that it i monitoring and we have had no problems.

I never had a reason to be in touch with the tech support for the solution.

The initial setup was pretty straightforward. It's an application that you can run on a Windows box. I have it running on a virtual Windows server, so it's not a standalone operating system, and it can come off as an application.

PRTG is relatively intuitive and fairly straightforward. It has net flow monitoring and that works all right. I would describe it as a decent middle-of-the-road solution. It costs about $500 a year, so if you're looking just to watch basic traffic and keep an eye on devices, it works fine.

I would rate PRTG Network Monitoring a seven out of ten.
