Featured Reviews

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.
Moshiur-Rahman Khan - PeerSpot reviewer
Offers perfect real-time bandwidth monitoring and SNMP functionality
The licensing policy needs to change. The current model requires customers to purchase a minimum of two thousand licenses, which is not flexible for all customers. They should consider a more flexible licensing approach. Furthermore, alignment with customer expectations rather than offering numerous features that are not requested would be beneficial.

Quotes from Members

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

Pros

"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"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 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."
"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."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"We have found the solution to be stable."
"An affordable solution for small organizations to do basic network monitoring."
"PRTG is good and very easy to use."
"The product's most valuable feature is network analysis."
"It provides a vast array of options for dashboard creation and monitoring of the activities within the environment."
"The product is easy to understand."
"It can identify downtimes and disruptions."
"The solution's ability to monitor each and every aspect of our devices, such as memory utilization and port connectivity, is valuable."
"I would recommend PRTG Enterprise Monitor to others as it works well with Android devices, and you can try the free version before purchasing."
"From a technical perspective, the product's most valuable feature is SNMP, an open standard monitoring protocol that works across various network devices and operating systems, including UNIX and Windows."
 

Cons

"Icinga’s automation could be improved."
"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."
"Icinga is a complex solution that's hard to learn. It's a powerful product for monitoring, but new users will have a hard time figuring out what to do."
"We have found some problems with Nagios, and support isn't very responsive."
"The tool currently fails to provide notifications to users."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"The user interface should be improved."
"One of the areas that are frustrating is remote monitoring for more than one machine."
"The licensing policy needs to change. The current model requires customers to purchase a minimum of two thousand licenses, which is not flexible for all customers."
"In my opinion, one area that could be improved in PRTG Enterprise Monitor is the capability to send SMS notifications. Notifications are crucial for alerting us to areas that require attention."
"There is no unified monitoring in PRTG. It needs a lot of improvement in terms of integration."
"The licensing policy needs to change."
"PRTG Enterprise Monitor should include more functionalities and features that are similar to SolarWinds."
"The solution could be improved by introducing security features similar to those available in Teams, as the current version only monitors devices and does not integrate IoT or OT devices."
"The solution could be improved by including a processing monitor, possibly with a language interface like Lua, allowing for writing custom sensors and processing outcomes of inputs."
"The solution could be improved by introducing security features similar to those available in Teams, as the current version only monitors devices and does not integrate IoT or OT devices."
 

Pricing and Cost Advice
