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…
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.

Quotes from Members

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

Pros

"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 artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"The solution is stable."
"Flowmon is more easy to understand and helps find network issues more quickly."
"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."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"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."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"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."
"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."
 

Cons

"If there was better visualization in Flowmon Solution it would be good."
"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."
"I do not know the detailed pricing."
"The licensing price could be better."
"Icinga’s automation could be improved."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"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."
"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."
"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."
"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"The tool currently fails to provide notifications to users."
 

Pricing and Cost Advice

"The price of the solution could be better."
"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"The licensing fee accrues only once, but that of support is annual."
"The solution is cheap."
"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."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"The solution is free to use."
"This is an open-source solution with paid support."
"We're using the free version of Icinga."
"The product is inexpensive compared to other DBM products."
