We are currently developing a check called SnapshotChangeRate to measure the change rate between two snapshots. With this check it will be possible to see how much data on a volume changes or grows.

In practice, SnapshotChangeRate will calculate the delta between the oldest and newest snapshot and put it in relation to the timespan between the snapshots: the change rate, measured in GByte / Day.

Find a first specification with an example on our website. We are happy to receive your feedback. Feel free to send us an email at il@netapp-monitoring.info or leave us a comment on this article.
