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

"Macros and the ability to connect it to Google Maps are valuable features."
"I would recommend Icinga; it's an open-source solution, it's quite easy and simple to use, and checks can be run with Python code and Shell Script code."
"The best thing about the solution is how it highlights errors, the issues, and what needs my attention. The solution directs me to areas that I should look for first."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"Icinga2 was designed to delegate, distribute and balance tasks between several nodes."
"The most valuable feature is one that not many are even aware of, as Icinga has a self-healing event handler where if the service is down, it is automatically restarted, and you can configure the handler to take action after the critical alarm without human interaction."
"Icinga has multiple automation and integration features. There is an API for everything and a web UI for configurations. The APIs enable you to automate tasks in Icinga. We can also use plugins to talk to the API. The Icinga Director talks to a database in the background, and you can import settings from the CMDB to all systems in Icinga."
"The solution has excellent redundant features."
"PRTG is simple to manage. First, you can create a template for a device, then apply it to hundreds of similar devices. That's a great advantage."
"Technical support is helpful."
"The installation is not that complex."
"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."
"It is a user-friendly solution."
"Accessibility, ease of use (Web GUI, MobileApps). In general, compared with other software"
"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."
 

Cons

"Sometimes, it is very hard to keep an overview of what's happening."
"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."
"One of the areas that are frustrating is remote monitoring for more than one machine."
"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."
"The installation and configuration are very complex."
"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."
"Scalability is problematic. If you have a stable environment it's good, but if the environment is growing, I had some problems with Icinga."
"I would like a more straightforward ability to create dashboards and maps. The network maps should be a bit more flexibility in the GUI to do what we need to do."
"This solution is a good product so far, but I haven't been using it long enough to know how it could be improved."
"Users need to buy the more expensive licenses if they expect to be able to scale."
"The clustering aspect needs improvement, as there is a bit of confusion about you do when hit that 5000 probe mark."
"PRTG Network Monitor should improve the NetFlow dashboard, there is no flexibility, and the NetFlow is not meeting the business needs."
"In the next release, PRTG Network Monitor should add a backup solution."
"Can be slow in the way it polls the different engines."
"PRTG access works best from the web GUI. There are dedicated apps on Windows/Android/iOS, but they are slow and don’t work as well as the web GUI."
 

Pricing and Cost Advice

"We're using the free version of Icinga."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"The solution is free to use."
"The product is inexpensive compared to other DBM products."
"The solution is cheap."
"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"This is an open-source solution with paid support."
"It's an open-source solution."
"Pricing for PRTG Network Monitor is a nine out of ten. It meets my company's budget and monitoring requirements. My company is on a perpetual license."
"We pay for a perpetual license and we have a support fee."
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"
"We are licensed for 2500 endpoints."
"We have an unlimited license for this solution."
"I would like better pricing models for smaller businesses. The free version is fantastic, but it's too restrictive. If they could just get up to 200 sensors for a reasonable fee for on-premise, I would give PRTG my credit card right now."
"The licensing fees are billed annually and there are no costs in addition to this."
"I rate the licensing for PRTG Network Monitor an eight out of ten."
