Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.

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 solution's most valuable feature is its simplicity."
"The solution is pretty stable."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"I can monitor a phone on a desk to very big servers of any company."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"The most valuable feature is the monitoring of processes."
"I can monitor a software made in-house to software of bigger companies."
"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."
"The network monitoring and configuration within this solution is very good."
"Thanks to this software and to the work of the support team, we have everything under control."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"The solution is so lightweight that with only 4GB of ram, it allows keeping track of up to two hundred agents from a single console."
"What I value most about Pandora FMS is the simplicity of working with it."
"Pandora's architecture is interesting. It's open so you can easily extend and enhance it. It's simpler to customize Pandora compared to other solutions. It's also scalable enough to support large environments."
 

Cons

"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"We'd like to see more integration capabilities."
"They need more documentation for the plugins."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"Third-party integration should be improved for some commonly used products."
"An update to the Android app would be appreciated."
"We would like the real-time monitoring of an interface to be improved within this solution."
"The price for Pandora FMS is expensive."
"I think some improvements to the Android app would be good."
"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."
 

Pricing and Cost Advice

"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"We are using the free version of this solution."
"Nagios XI is an expensive solution."
"Nagios XI is open source."
"As it is not an agentless tool, I think it is expensive."
"Licensing costs are reasonable."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
