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.

Quotes from Members

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

Pros

"We can monitor multiple sites using the product."
"I really like the auto-discovery feature."
"The alerting system in Checkmk really works properly."
"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."
"Overall, from one to ten, I rate Checkmk a nine."
"The initial setup of Checkmk was easy...It is a very stable solution."
"Checkmk helps me compare data and foresee issues."
"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."
"Since we started using OpMon, we have increased our assertiveness and consequently reduced costs with fewer errors."
"As a consulting company we implement management solutions to a large variety of companies and after working with OpMon our project time was reduced and we can offer a different solution to each customer."
 

Cons

"If an alert is generated for a specific pattern in the log, and if Checkmk catches that log, it will stay there even after the alert is resolved."
"The initial setup is a bit complex."
"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."
"It is easy for tech-savvy people, but newcomers might find it intimidating."
"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."
"In Checkmk, the documentation can probably be improved a bit more."
"Checkmk does not allow running scripts at varying intervals."
"Infrastructure and business monitoring services need improvement."
