A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

The open architecture is easy to extend and enhance
Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas. They could improve their management console's ability to monitor large environments could be improved. For example, SNMP management is only partially integrated into the management console.

Quotes from Members

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

Pros

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It's very easy to manage and monitor it."
"Being open source lets us customize it for our monitoring needs, saving us money."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"The support from Pandora FMS is legendary."
"The most valuable feature is that it is an all-in-one monitoring system."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"It is easy to create your own custom modules if you just know a little bit of scripting. If you have unique requirements, you can just make your own modules. You can even grab checks from other vendors. There are open-source checks for various things such as SMTP, etc. There is a long list of different ones from Nagios. You can just use them, and within seconds, you get yourself a check that is monitoring whatever you need. It is really flexible. I guess that's why they call it Pandora Flexible Monitoring System (FMS). It is reliable. It does the job, and it alerts. It is also surprisingly feature-rich. Our network guy just recently asked about a particular protocol to monitor the bandwidth on the network, which is not a common protocol. When I looked it up, and I found that they cover it. It is very mature for a not-so-known product."
"Stability is where they shine. It has been super stable. We have high-end monitoring for our data centers. We monitor all kinds of metrics in our two data centers. We monitor maybe over 2,500 checks, and the product that has been successful and always alerting us is Pandora."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
 

Cons

"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"A nice feature in the next release would be an automation module to run workflow actions."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"Improvements are needed for server and network discovery, including service-based discovery."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"This solution requires proper training to get 100% out of it."
"It would be helpful to include the generation of reports for times that the network was out of service."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
