Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Generates close to real-time alerts so users can resolve issues, but needs more integration and public cloud monitoring features
As Zenoss Service Dynamics is more for network-centric devices and you want to monitor, for example, a server, its services, IP addresses, and interfaces, if it's a network and you're going to monitor multiple items, you'll be charged multiple times. This is what Zenoss Service Dynamics needs to improve to make sure that customers pay just one fee to monitor the entire server. What I'd like to see in Zenoss Service Dynamics in the future is a public cloud monitoring feature, particularly for the Azure public cloud. Another additional feature I'd like to see in the next release of the solution is integration with the Azure public cloud because I know that there are some services from Azure that Zenoss Service Dynamics is currently unable to monitor.

Quotes from Members

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

Pros

"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"I really found Nagios a perfect fit for us and a good product to work with."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"Nagios is the best software of its kind if you have time for configure any host and network, and you can do quite everything with a bit of scripting."
"I can monitor a software made in-house to software of bigger companies."
"The alerting system is very effective."
"The custom built integration is one of the most valuable features because you can see all the especially critical items."
"It is the most flexible solution of this type, but it takes time to adapt."
"The product offers good documentation that helps with initial training."
"Zenoss is more complex than LogicMonitor, but scalable and hugely customizable."
"The most valuable feature is the flexible discovery mechanism."
"It's easy to use."
"It is very cost-effective compared to the tools I worked with in the past."
"Overall, it's a great solution, and I consider it to be one of the best."
 

Cons

"Technical support is an area that needs improvement. It is not available 24/7."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"It can be quite difficult to know which drivers and agents to use when setting up."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"I think that the community needs to concentrate development to get a standard GUI (Adagios is a side project) and gives the user a better notification system."
"It's in need of more standard plug-ins."
"This solution is complex for beginners so it takes some time to learn."
"Now it is stable, but they should design threshold parameters in percentage instead of raw values."
"The AI aspect needs to improve."
"There is room for improvement with the administrative part. They introduced Control Center to manage things in Zenoss 5. The services that Zenoss provides remained the same, but the administrative part, since they introduced Docker, etc., has become a little complex"
"The inclusion of a feature to show a graphical view of the network would be a helpful improvement."
"It would be ideal if the product offered sound alerts."
"There was a problem with Zenoss and storage monitoring."
"As Zenoss Service Dynamics is more for network-centric devices and you want to monitor, for example, a server, its services, IP addresses, and interfaces, if it's a network and you're going to monitor multiple items, you'll be charged multiple times. This is what Zenoss Service Dynamics needs to improve to make sure that customers pay just one fee to monitor the entire server. What I'd like to see in Zenoss Service Dynamics in the future is a public cloud monitoring feature, particularly for the Azure public cloud. Another additional feature I'd like to see in the next release of the solution is integration with the Azure public cloud because I know that there are some services from Azure that Zenoss Service Dynamics is currently unable to monitor."
 

Pricing and Cost Advice

"The pricing is high with separate licensing for the product and support."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"As it is not an agentless tool, I think it is expensive."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is an expensive solution."
"Nagios XI is open source."
"There are additional costs you'll have to pay apart from the license fee for Zenoss Service Dynamics. I can't remember exactly how much my company is paying because I don't handle the finance part, but the cost is paid annually. On a scale of one to five, with one being the cheapest and five being the most expensive, I'm rating the solution three out of five."
"It depends on the customer, what he wants."
"The pricing depends on the environment, the number of services, and the size of the data center. It can go from $100,000 to a million dollars."
"It is very cost-effective compared to the tools I worked with in the past. The company is gaining a lot with respect to the cost factor. It provides agentless monitoring and in a very cheap way."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
