This is caused by the storage code getting empty data. Either the end device is reporting zeros or (more likely) the SNMP query is timing out.

You'll likely get other graph gaps with both.

Hello,

On our NAS devices, there are multiple entries where the storage size changes to 0 and then changes back to its original number. Is this something that can be changed? Or anybody know why it is doing that? I’m wondering if that is going to cause an issue if I enable an alert checker for disk size changes.
