Harrison Bulley - PeerSpot reviewer

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

"People should know that it is simple and advanced."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"An affordable solution for small organizations to do basic network monitoring."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"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."
"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."
"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"If you have a small infrastructure or a small number of devices that you want to monitor, then I think it's a good solution."
"It has provided us with early warning for potential issues and has stopped potential downtime before it occurs."
"From my somewhat more high-level view, the summary dashboards are excellent, they give me what I need, and having spoken to the operations guys, it gives them everything they need."
"I found PRTG Network Monitor very useful for troubleshooting and monitoring the utilization of either the network or server."
"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."
"It is a user-friendly solution."
"Every monitoring session features similar capabilities."
"PRTG Network Monitor is user-friendly and takes just one click to install the solution in Windows."
"I would be happy to recommend PRTG; I have no qualms with it whatsoever, it does what we need it to do and is flexible."
 

Cons

"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."
"The connection between Icinga and Icinga Web."
"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."
"One of the areas that are frustrating is remote monitoring for more than one machine."
"The user interface should be improved."
"The solution lacks many features important to higher-level IT management and network support."
"It is not really adequate for our current needs. It causes additional issues which we have to work around and takes us time that a better solution would not."
"We have found some problems with Nagios, and support isn't very responsive."
"I would like to see a more robust platform and a new dashboard. In addition, the code is good, but it needs improvement."
"The automation should be improved."
"The technical support from PRTG needs significant improvement."
"PRTG can fix that, but it's only good for small workloads."
"PRTG does not allow us to scan devices like we can scan software or another problem in it. Also, I cannot draw graphical graphs in Woodview/look. Another problem is that we cannot draw a good diagram in PRTG."
"PRTG Network Monitor can improve by adding prevention and detection features."
"PRTG Network Monitor could improve by having descriptions for the tab usages. The dashboards or interface could be easier to understand."
"I am not sure the solution is giving me all the needed feedback that we need. When something goes off on our IT infrastructure, it does tell me. However, it would be nice if it gave more intuitive information, e.g., the hard drive has gone up by 60 percent in an hour."
 

Pricing and Cost Advice

"We're using the free version of Icinga."
"This is an open-source solution with paid support."
"The solution is free to use."
"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"It's an open-source solution."
"The solution is cheap."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"The product is inexpensive compared to other DBM products."
"The pricing is okay and it is cheaper than some competing products."
"If you're looking for a cost effective software I’d suggest this product."
"PRTG Network Monitor is very expensive."
"The scalability is there, but smaller companies might need CAM software to be able afford the product."
"We are satisfied with the price."
"Right now, the smallest sensor pack that they have is just a bit out of range for me, as a business. This kills me, as I need the product. Therefore, there is always a balance between needing to buy it or continuing their free version."
"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."
"When you have a lot of devices, PRTG Network Monitor can be costly."
