[Xymon] Xymon DISK free space

Hello,

I am not good in english, so i am not sure how to find required feature.

Is it possible to monitor free disk space in MB ?

Example:

We have database filesystems in Terabytes, but DB does not increase too much. So Even it is 100% utilization, it may still have 10GB free space and datafiles can be created without problem.

We tweaked old BigBrother monitoring and disable percentage by setting alerts to 101:101 (percent) and add 5000000:3000000 ( 5G:3G)

So it could look like in xymon syntax DISK /db/filesystem 101 101 5000000 3000000 or DISK /db/filesystem 5G 3G

Is it possible in xymon ?

Thank you

W.
