Cluster Summary
This section of the report provides a overview of the storage system, with links to relevant components.
Cluster
Name of the OpenStack Swift cluster.
Last Poll Time
Date and time of the last successful data collection cycle.
# of Proxy Servers
Number of front-end proxy servers in the cluster. Drill down to the Host Capacity & Utilization report to view the details for these servers.
# of Storage Nodes
Number of storage nodes in the cluster. Drill down to the OpenStack Swift Storage Node Summary report.
# of Devices
Number of devices across all nodes in the cluster. Drill down to the OpenStack Swift Device Summary report.
# of Zones
Number of zones in the cluster. Drill down to the OpenStack Swift Storage Utilization by Zone report.
 
Physical Summary
 
Raw Capacity
Sum of all storage nodes’ raw capacity (# of drives * drive sizes). This value includes overhead.
Logical Summary
 
Capacity
Sum of the storage nodes’ allocated capacity (logical)
Used
Sum of all storage nodes’ used allocated capacity (logical). This is calculated as (# of objects * object sizes).
Usage
This progress bar indicates usage (red, yellow, or green) based on Used/Capacity.
# of Accounts
Number of accounts defined for the cluster. Drill down to the OpenStack Swift Storage Utilization Account report.
# of Containers
Number of containers defined for the cluster. Drill down to the OpenStack Container Summary report.
Performance
 
Avg IO/sec
Average I/Os per second, for all storage nodes for the last collection cycle.
Avg Resp Time
Average operation response time for all storage nodes for the last 24 hours. This is the weighted average of all devices, based on I/O per second for the same period.
CPU Usage
This progress bar indicates the CPU utilization of all processors in all storage nodes.
