[Observium] FW: Correct metrics for storage_free checker

Hi,

I'd like to use the storage_free (instead of storage_perc) to get an alert if disk space is below 500 MB. What kind of units are used (byts/mb/kb/gb) ? I was thinking the rule would be like 'storage_free lt 500' if it's in megabytes. Or should i use 'gb' or 'mb' in the equation?

Regards, Hilco
