Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
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 alerting system is very effective."
"I can monitor a phone on a desk to very big servers of any company."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"It is an open-source platform with valuable features for performance and stability."
"The installation is no problem. I've installed Nagios several times."
"I can monitor a software made in-house to software of bigger companies."
"Nagios XI is stable."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"The product is easy to use and you don't need to have any training. You can use it even if you don't have an IT background."
"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."
"The product is easy to understand."
"If an event is detected, such as a resource running low on storage or RAM, the product will notify you via email. Upon receiving the notification, action must be taken to address and resolve the issue. The feature I find most effective is its comprehensive nature. It's like having a permanent eye monitoring the network and all its nodes. Instead of manual monitoring, it detects anomalies automatically and alerts us accordingly."
"The solution offers perfect real-time bandwidth monitoring and SNMP functionality."
"The solution's ability to monitor each and every aspect of our devices, such as memory utilization and port connectivity, is valuable."
"The product's most valuable feature is network analysis."
"I would recommend PRTG Enterprise Monitor to others as it works well with Android devices, and you can try the free version before purchasing."
 

Cons

"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"The product's stability could be even better."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The user interface needs improvement."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"I would like to see support for notification via SMS."
"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 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 licensing policy needs to change."
"The support must be improved."
"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."
"PRTG Enterprise Monitor should include more functionalities and features that are similar to SolarWinds."

"They should work on minimizing false positives by sending alerts promptly and confirming errors with minimal troubleshooting requirements."
