We would like to do disk space alerting based on the size of a disk. I noticed cdm probe can now collect disk size which is great. How can we use that information so that we can apply different thresholds for different disk size in an automated manner (possibly using MCS):


  • 0-100 GB -> 15% threshold
  • 100-500 GB -> 10% threshold
  • >500 GB -> 5% threshold


The reason we need this is because 5% free on 50 GB disk is much different than 5% free on 2 TB disk. So, the existing options of using either % or MB free will not work. We need to use some combination of multiple metrics like disk size and disk free to do effective disk monitoring.
