Quick identification of network issues enhances performance monitoring
We will try to Proof of Concept (POC) to a client in Taiwan. We just use the features for the Network Performance Monitor (NPM) Flowmon is more easy to understand and helps find network issues more quickly. We need this solution to monitor the network performance. We started using it three…

Valuable reporting and alert system with room for PDF export improvements
The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Quotes from Members

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

Pros

"The solution is stable."
"Flowmon is more easy to understand and helps find network issues more quickly."
"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"Flowmon is more easy to understand and helps find network issues more quickly."
"It is an open platform, so in terms of integration, we are quite happy. We can integrate it with other SNMP solutions. We can also integrate it with security solutions, such as a SIEM solution."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"The good thing about Nagios Core is it covers everything."
"I would rate the overall solution ten points out of ten."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"We use the product to monitor server applications."
"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"Nagios Core is very configurable. Whatever you want, you can do it."
 

Cons

"The licensing price could be better."
"If there was better visualization in Flowmon Solution it would be good."
"I do not know the detailed pricing."
"It would be helpful to have more details about the monitoring of the infrastructure. It should have support for SNMP. This is something that is currently not there in the product."
"The interface could be improved."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"There is room for improvement in the graphics."
"Would benefit from aggregations if a particular server goes down."
"The user interface could be more interactive because it is pretty basic."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"The core version is no match for the XI version."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
 

Pricing and Cost Advice

"The licensing fee accrues only once, but that of support is annual."
"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"The price of the solution could be better."
"Nagios Core is a cheap solution."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"The product is cheaply priced."
"It's free."
"It's free."
"Most the plugin features are free."
"I would rate the solution's pricing an eight out of ten."
"We are using the free version."
