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

Pros
The most valuable feature is the ability to span multiple technologies and multiple vendors.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.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.There is a simplicity to setting up the extra sensors. It's really easy for us to build infrastructure and start monitoring very quickly.

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.BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required.Nagios XI helped me to draw the network and check for system failures.The ability to set up templates and groups of checks, as well as customize the checks themselves.Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want.You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange.

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
The dashboarding definitely needs improvement.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 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.The thing that we do struggle with a bit is in the historic data. If I want look over 30 days, because it averages out onto one graph, you can't zoom in and drill down information.

The interface could be more user-friendly.The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors.The Configuration Wizard needs improvement, because not all vendors are present.Improve the documentation, examples, and best practices, therefore users can understand how to do things.Nagios XI can improve its GUI for users with a new look.The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it.The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module.The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them.

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
We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization.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 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.If you are not too sure about it, try the free version. Then, if you like it, you can go to the paid version and roll it out.

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.For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value.You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI.The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily.
