Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Personalized metrics; simplicity of data
My primary use case for Pandora is monitoring This solution has helped us improve our organization by allowing us to create a lot of metrics on several platforms, including Windows, Linux, and Unix. We then use these Pandora metrics to create an interface. We then pass the interface off to the…

Quotes from Members

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

Pros

"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"Provides timely notifications."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"We use the product to monitor server applications."
"The application performance monitoring feature is valuable."
"You can configure several types of architecture for high availability or load balancing."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"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."
"It allows me to quickly see the status of all of my printers, switches, computers, and virtual machines to determine if any system has fallen."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
 

Cons

"The dashboard and monitoring features could be improved."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"The mapping is a little hard."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"The alerting mechanism in Nagios Core could be improved."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"It is a bit slow due to latency."
"Their support is good, but it is just online communication. It would be great to be able to just call someone and talk to them instead of always writing. It works well for me because I am a decent communicator in email, but some people might find it difficult to describe in a written fashion and communicate with them that way. There is a learning curve to the interface, but once you get used to it, it is actually very powerful. They have a lot of options, but people struggle with the interface. They've improved it though, and it is getting better. They need to keep improving the learning curve to help buy-in. I'm the guy that manages it, so I'm comfortable with it. They can refine the upgrade agents to be easier. They can also do more refinement in end-user usability because not everyone is strong technically, and people who aren't strong technically might be averse to the product, even though it has come a long way. It has a complete GUI and everything."
"It would be useful if Pandora FMS included an ISO image (or «software appliance») for each big company that leases virtual private machines (VPS), just like in AWS."
"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."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"The price for Pandora FMS is expensive."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
 

Pricing and Cost Advice

"It's free."
"Nagios Core is a cheap solution."
"Lessening the price point would be an improvement."
"We are using the free version of Nagios Core."
"The solution is expensive."
"Nagios Core is an open source solution, and there are no licensing fees."
"I would rate the solution's pricing an eight out of ten."
"We are using the free version."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
