The simplest way could be to create your own custom measure for the "Disk Storage Utilization" to define your own thresholds and then you can also plot a chart to show the visualization.
Below is an example of a average measure splitting by agent host.
The below example is splitting by a disk.
Thanks for your reply.
I think my question was not correct, I need the incident to tell me which file system exceeds the set threshold, since upon receipt of the email notification, only the host agent appears.
I crated a sample measure and incident with the upper warning and upper severe to generate the incident and the below screenshot is the result of that where we can see that the disk "C" voilating the thresholds.
