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

"I really like the auto-discovery feature."
"We can monitor multiple sites using the product."
"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."
"The initial setup of Checkmk was easy...It is a very stable solution."
"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."
"The most valuable feature of the solution is that it has a lot of different pieces, and they all work together...It is a very scalable solution. Scalability-wise, I rate the solution a ten out of ten."
"Checkmk helps me compare data and foresee issues."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"It's great for monitoring IT services infrastructure."
"I can monitor a software made in-house to software of bigger companies."
"Nagios XI is stable."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"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."
"The installation is no problem. I've installed Nagios several times."
"The solution has a lot of plugins and scripts integrated with it."
"An excellent solution that is easy and intuitive to implement."
 

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."
"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."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"The initial setup is a bit complex."
"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."
"Checkmk does not allow running scripts at varying intervals."
"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."
"In Checkmk, the documentation can probably be improved a bit more."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The installation and monitoring need improvement."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
 

Pricing and Cost Advice

"The product is affordable."
"The price of Checkmk is cheaper compared to other enterprise products."
"Checkmk is a fairly reasonably priced solution."
"The licensing fees for this solution are approximately $3,000 USD per year."
"We are using the free version of this solution."
"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"As it is not an agentless tool, I think it is expensive."
"Nagios XI is an expensive solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
