Quotes from Members

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

Pros

"Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well."

"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."

"We have used this product now for quite some time and we are happy with it."

"I like the way the solution sends alerts and how it keeps on escalating them."

"The solution's most valuable feature is that it offers proper alerting capabilities."

"The most valuable features are the reports and the way it generates the report in a graphical manner."

"The reporting structure and the feature set are valuable to me."

More Nagios Core pros

"We are able to control our business with this all-in-one monitoring tool."

More Pandora FMS pros

Cons

"The user interface could be more interactive because it is pretty basic."

"Nagios Core would benefit from aggregations if a particular server goes down."

"This is the open source product, so it's a toolkit rather than a complete solution."

"We're using the free version, which limits us in terms of the things that we can do."

"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."

"I believe Nagios Core will need to provide an option for big data platforms in the future."

"The interface could be improved."

"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."

More Nagios Core cons

"A nice feature in the next release would be an automation module to run workflow actions."

More Pandora FMS cons

Pricing and Cost Advice

"Nagios Core is free to use."

"The enterprise version has technical support. The version we are using is free."

"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."

"Lessening the price point would be an improvement."

"We are using the free version."

"We are using the open-source, unpaid version."

"Nagios Core is a cheap solution."

"I would rate the solution's pricing an eight out of ten."

More Nagios Core pricing and cost advice

"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."

"You have to pay for the number of agents and models that you are monitoring. I would rate the cost at three with one being the most expensive and five being the cheapest."

"In terms of money, the Enterprise version is the cheapest that I have found after a market study."

"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."

"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."

"Pandora FMS is easy to implement and the pricing of licenses is competitive."

"My rule of thumb would be that if you need more than thirty agents, and you lack an automation tool such as Chef or Puppet, you will save a lot of time and money going to the Enterprise edition."

"You get the license and it includes updates, new versions, and access to the complete library of modules."
