Snapshot Storage If the sum of the snapshot capacity exceeds the set size, the first created snapshot among all snapshots is deleted.

[Note] The number of subnets available for each project is limited to 3 as of Februrary 2024. To increase the limit, contact the Customer Center.

The default search period is the latest 1 hour, and you can search any period you want through the search period filter. Descriptions of monitoring metrics are found in the table below.

Metric Unit Description
Storage capacity byte Display the total capacity of storage and the capacity in use.
Storage usage % Display the capacity in use as a percentage of the total storage capacity.
IOPS OPS Display storage operations per second.
Latency usec Display storage latency time.
Snapshot number - Display the number of snapshots in storage.
Snapshot capacity byte Display the amount of capacity that storage is using for the snapshot.
Inode - Display the number of storage inodes.
Storage status - Display storage status.
Number of client connections - Display the number of clients connected to storage.
