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.

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

"Nagios is able to minimize server downtime and this in turn helps to generate more revenue."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"Open source and very flexible, with a large ecosystem of tools and custom monitors built up around Nagios."
"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."
"It sends alerts to the right people which ensures there is no delay in the correct person or team looking into issues, and it has helped to reduce downtime in the production environment to almost zero so we now spend less time on network or server administration."
"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"
"The most valuable feature is that it is an all-in-one monitoring system."
"Thanks to Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"The support is excellent for this product; their response time is very fast, and they are very knowledgeable."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"Network monitoring is fun again with Pandora FMS."
"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."
"The solution has good dashboards and graphics."
 

Cons

"Nagios Core does not have a graphic display."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"There is room for improvement in the graphics."
"The mapping is a little hard."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
"Some of the reporting functionality is a bit basic and configuration is a chore although by the use of NagiosQL this can be made a lot easier."
"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."
"We would like the real-time monitoring of an interface to be improved within this solution."
"An update to the Android app would be appreciated."
"A nice feature in the next release would be an automation module to run workflow actions."
"This solution requires proper training to get 100% out of it."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"In the future, we may have double the number of devices, and we do not want to have any issues with performance in the data display."
 

Pricing and Cost Advice

"We are using the free version."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"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."
"I would rate the solution's pricing an eight out of ten."
"We are using the open-source, unpaid version."
"Nagios Core is free to use."
"Most the plugin features are free."
"Nagios Core is a cheap solution."
"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."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
