A stable, scalable and cost-effective solution that helps with inbuilt scripts for easy modification
I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built.

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

"There's a module called Icinga Director, which helps us configure the product using an intuitive interface through clicks instead of creating a text configuration. It's very helpful for us."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"Icinga does the job and is fairly stable."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"We have found the solution to be stable."
"The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated."
"I like the ability to amend and adjust things really easily, which is useful in a case where you could make it auto-discover and then set a template to say all of these applications or servers under this template have an automatic threshold set that you’d set up manually."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"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."
"I think net flow is PRTG's most valuable feature because it doesn't cost much for us because the net flow sensor is already included in the PRTG license. We can monitor our traffic in our proxy and router."
"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."
"The reporting module is easy to configure."
"The most valuable feature is the notifications. As long as you spend time and think about what and when you want to be notified, it's always accurate. It is always there. I find things out before my Internet provider."
"Every monitoring session features similar capabilities."
"Its proactiveness is its most valuable feature. We already know when we come in, in the morning, if a server or site is down, as opposed to someone telling us."
"The solution is scalable."
 

Cons

"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"Icinga’s automation could be improved."
"We have found some problems with Nagios, and support isn't very responsive."
"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."
"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."
"I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"A room for improvement in PRTG Network Monitor is its sensors. Its application technology sensor, such as the IAS, .NET, etc., needs some improvement because it doesn't work as expected. For example, the IAS sensor doesn't give immediate information, and the information you get from it isn't of good value. The web GUI of PRTG Network Monitor also needs improvement because errors keep popping up if it's not been updated to the latest version. What I'd like to see in the next release of the tool is end-to-end topology mapping for the business model, and that should be required. There has to be a technical map. Technical mapping and topological creation are missing in PRTG Network Monitor, so I would like to see those in the future."
"I know we're going to move to Docker applications and I understand that PRTG does some monitoring regarding this. I do not know if it is complete. If it's not yet complete, it's something they should consider improving."
"The scalability of this solution could improve as well as the automated provisioning of the infrastructure."
"Sometimes, our PRTG Network Monitor system crashes and a lot of sensors go down."
"Mostly, this software has sensors for devices to monitor specs and you can build or develop or modify various sensors, according to your company's needs. But you may need to do that with coding or plugins or with the support of Paessler AG, the manufacturer."
"PRTG Network Monitor needs to show bandwidth utilization in proper graphs. It isn't easy to learn."
"I would like to see Office 365 monitoring. Essentially, it doesn't do it. I assumed not at all, but apparently it does it slightly. However, due to issues with APIs, they currently don't provide full monitoring for O365."
"Users need to buy the more expensive licenses if they expect to be able to scale."
