How to create a custom check that generates a graph

General
1

Hello, I created a custom check for Windows that returns a value representing the size of a file in MB. Checkmk reads the values, but it doesn’t create a graph, which I need to understand the growth trend. What should I add to the script to ensure a graph is generated?
The script is a .bat file that internally runs a .sql file, which returns the data I need to monitor.

Thanks in advance

OS: Rocky9
Checkmk: Raw Edition 2.3.0p6

Hi @asyscom1

I think this section of the “Custom check plugins” article could be helpful: Writing agent-based check plug-ins

If your Check is a local check, this is might be helpful: Local checks
