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.

Enables seamless global client monitoring with reliable remote connectivity
I use the solution to provide a perfect environment for remote connectivity with my clients. Many tools that I require for system maintenance are included. I can easily monitor all of my clients throughout the world I did not give much thought to it, however, improvements could be made to Zabbix.…

Quotes from Members

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

Pros

"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"The apply rules feature saves a lot of time."
"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."
"Icinga does the job and is fairly stable."
"Macros and the ability to connect it to Google Maps are valuable features."
"An affordable solution for small organizations to do basic network monitoring."
"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 initial setup is very simple."
"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."
"PRTG Network Monitor helped prevent incidents by creating an alert to the DL when servers go down, notifying me before it became a bigger problem."
"It allows us to directly add individual VMs independently."
"Ability to create a dashboard inside software monitoring."
"The bandwidth monitoring is a very attractive feature, it can tell you the bandwidth utilization while it is attempting to connect to the host for feedback."
"The most valuable features of PRTG Network Monitor are user-friendly, and the graphical interface is good for all the network devices that are mapped in this organization. It's very easy to find reports for any devices that we are looking for."
"PRTG Network Monitor helps us quickly and easily discover a large number of sensors, so we can spend minimal time monitoring customer sites."
"It provides high scalability, alerting, notification, templating, and end-to-end security."
"The most valuable features in Zabbix are those that help us overcome bottlenecks in CPU usage, as well as reduce memory delay. I know that we have only reached the tip of the iceberg of what Zabbix's features can do for us, and we have not used all of them yet."
"The level of discovery-based configuration that lets us auto-configure the monitoring for various systems is a valuable feature."
"The resource usage, CPU utilization, disk usage, network monitoring, network performance, and alerting features are invaluable."
"We value the auto-host discovery, template import, bulk import/export features. Newer versions also add nice features, such as multi-IP per host."
"SNMP monitoring, source discovery, and alert triggering are most valuable."
"The most valuable feature is that it provides network segregation for server monitoring."
"It's a very reliable platform and we've never had any issues regarding the scalability or the stability of Zabbix."
 

Cons

"The tool currently fails to provide notifications to users."
"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."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"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."
"The user interface should be improved."
"One of the areas that are frustrating is remote monitoring for more than one machine."
"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 clustering aspect needs improvement, as there is a bit of confusion about you do when hit that 5000 probe mark."
"It would be nice if it gave us alerts via Gmail or SMS message."
"When it comes to third-party integration, one of the things we were looking at was putting some sensors onto our firewall, for instance. If there were a little bit more documentation and some step-by-step guides around that, that would be useful for us."
"Users need to buy the more expensive licenses if they expect to be able to scale."
"Integration into service management ticketing systems could be better. They should simplify the integration into big service management platforms like ServiceNow, Remedy, and Cherwell. They're really into monitoring, but they don't do any self-resolution. It would be better if the company moved more into the AIOps space so that you could actually kick off some remedies. I know that you can execute some commands from the tool, but you need to develop those all yourself. It would be really handy if they had some auto-remedy scripts that they could develop on top."
"In the next release, PRTG Network Monitor should add a backup solution."
"PRTG Network Monitor can improve Layer 2 and Layer 3 network maps and the GUI more user-friendly. Additionally, they should bundle the features so I can monitor everything on one particular device."
"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."
"Correlation of events would be a wonderful addition."
"I think the reporting part of Zabbix can be improved in terms of more user-friendly graphics to display the collected data. Many simple users who don't know how to use Zabbix properly might get confused by the reporting, although at the same time it is very versatile for my company."
"The product could be more secure and more stable."
"Zabbix isn't a great tool for cloud-specific monitoring - its connection to public clouds needs to be improved. Other areas for improvement would be the lack of dashboards and integrations."
"It should be easy to modify the front end."
"We would like to see the addition of automatic push functionality to this product. This would save time when monitoring our servers and networks as, at present, we have to manually install the Zabbix agent on any hardware to be monitored."
"I am having difficulties connecting it to Grafana, as well as some of the other plugins like Kibana."
"I would like to remotely connect to the computer, and Zabbix doesn't have this capability."
