Utilizing data monitoring capabilities and scripting potential to optimize system management
I frequently program functions with PowerShell, and although Bash could be used, my specialization is in PowerShell. Two of us focus on programming in PowerShell for infrastructure optimization. I set up a dedicated server to run scripts every hour, generating files for Checkmk output. However, Checkmk does not allow running scripts at varying intervals. I am working on this in the raw version of Checkmk.

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.

Quotes from Members

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

Pros

"The initial setup of Checkmk was easy...It is a very stable solution."
"Overall, from one to ten, I rate Checkmk a nine."

"Nagios XI is stable."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements, it is flexible and easy to integrate with our systems, and you can customize the solution by adding additional features using code."
"It has a lot of flexibility for customization and a wide range of metrics."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
 

Cons

"Checkmk does not work too easily with the PowerStore. I use a PowerShell script as Checkmk runs on Linux and a Windows system, connecting with the Checkmk agent."
"The initial setup is a bit complex."
"In Checkmk, the documentation can probably be improved a bit more."
"Checkmk does not allow running scripts at varying intervals."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"The main challenge for us is that we're moving from Nagios to Checkmk, and we're still getting used to the new way of working."
"Sometimes we receive alerts, and it can become annoying when you acknowledge an alert. It is very clunky when you acknowledge the alert. The process is not very intuitive, and there are instances where it feels a bit cumbersome to acknowledge an alert."
"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."
"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."
"The installation and monitoring need improvement."
"I would like to see support for notification via SMS."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"Its simple deployment but complexity comes once you have to import more plugins."
"Implementation on Windows was painful."
"Reporting items needs more improvement and need to be more flexible based on customer needs."

"Checkmk is a fairly reasonably priced solution."

"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."
"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."
"Licensing costs are reasonable."
"As it is not an agentless tool, I think it is expensive."
"We are using the free version of this solution."
