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

"The reporting structure and the feature set are valuable to me."
"Nagios Core is very configurable. Whatever you want, you can do it."
"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."
"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."
"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."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"The network monitoring and configuration within this solution is very good."
"What I value most about Pandora FMS is the simplicity of working with it."
"The network monitoring and configuration within this solution is very good."
"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."
"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."
"Each of these points I think represents the keys as to why this software works in my jewelry stores, as it gives me greater control over all of the devices, the best performance, and I can interpret the data easily and much faster, with excellent results."
 

Cons

"Application level monitoring is limited."
"Nagios Core does not have a graphic display."
"The core version is no match for the XI version."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"The UI is a little outdated and graphics could be displayed in a better way."
"Would benefit from aggregations if a particular server goes down."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"Improvements are needed for server and network discovery, including service-based discovery."
"We would like the real-time monitoring of an interface to be improved within this solution."
"I think some improvements to the Android app would be good."
"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."
 

Pricing and Cost Advice

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios Core is a cheap solution."
"It's free."
"Lessening the price point would be an improvement."
"We are using the open-source, unpaid version."
"The enterprise version has technical support. The version we are using is free."
"The product is cheaply priced."
"Nagios Core is an open source solution, and there are no licensing fees."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
