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

Pros
The fact that I can use custom MIB files to customize my sensors for the things that are not there as a default is a good feature.It is a central solution in terms of how to actually use it. It has a very easy dashboard. Everything is concise. We are able to create custom sensors. For different parts of the business, we have many products across many environments, and it works for everything.The most valuable feature is the ability to span multiple technologies and multiple vendors.We can see trends for a lot of different things, such as hard drive space and bandwidth usage. We can see and plan for the future by knowing, "We're sort of at 75% capacity now. In three months time, we know we're going to be up to 90%,so we need to plan ahead for it, getting upgrades booked in place." Since things like this take time and effort, it's handy to see trends into the future of where our company is going.The solution provides us with needed feedback on our IT infrastructure. It gives us really good quality of service when it comes to monitoring of available space and available resources. It allows us to preempt issues before they become a problem for the business.It is easy to use and intuitive, which is really important. It does what it says on the box by giving you a visual of the state of what is going on at any one time.It is pretty simple to use, which is always a good thing. It's been very reliable in updating us if any issues crop up.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 features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful.An excellent solution that is easy and intuitive to implement.The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need.The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers.This is a very good solution and it is simple to use, for any company.The most valuable feature is the monitoring of processes.I can monitor a phone on a desk to very big servers of any company.I can monitor a software made in-house to software of bigger companies.

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.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.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.

Cons
I have an issue with DFS, distributed file services... there isn't one by default. Taking into account the difference between DFS and DFSR as well would be great.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 dashboarding definitely needs improvement.The only sort of limitation is the actual probes. So, if you don't have enough probes on there, you can over flip them and cause the WMI sensors and SNMP sensors to sort of overload. Sometimes, they might timeout for a minute, but they do come back.The desktop app is the one area where it do with some improvement. From a user's perspective, I would like to be able to get more out of the desktop app as opposed to where we are now with it.While the desktop app is good, they could slightly improve it. We would like it to be a single pane of glass. At the moment, you can only see certain portions of information. You have to scroll through to make it more granular. We want them to develop the desktop app to be more user-friendly.Once you start going above 5000 sensors, things do start to get a bit shaky. There are some best practice out there that you will need to adopt and be aware of.We would like more cloud native sensors for AWS, Azure, Google Cloud, etc. A lot of businesses are moving in that direction, so having something where we can pull performance stats out of these cloud services would be great for us.

There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple.They need more documentation for the plugins.I would like to see more customization in the network map because it is a bit tricky to use it.I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space.I would like to see support for notification via SMS.The interface could be more user-friendly.

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.

Pricing and Cost Advice
At the moment I'm only using 500 sensors. I pay yearly, so it's a cost that's easily swallowed.We used a product called SolarWinds in the past, and its cost was high. Whereas, PRTG came in at a third of SolarWind's cost.Cost was a factor when selecting this solution, but it just did everything we wanted it to do.Our licensing costs are 10,000 euros over three years.We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization.We looked at PRTG and SolarWinds. From a cost side perspective, compared to PRTG, and from what you get back from it, PRTG was sort of a hands down the winner.While I am not the person who deals with pricing, I would say that we pay around 1000 pounds a year.It is about £4,500 for the first year, then about another 15 to 20 percent annually after that. So, we are looking at about £1000 running costs a year. When you think about how much an outage costs per minute, it's negligible.

The pricing is high with separate licensing for the product and support.The licensing fees for this solution are approximately $3,000 USD per year.This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years.We are using the free version of this solution.It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise.
