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. |
Raw Capacity | Sum of all storage nodes’ raw capacity (# of drives * drive sizes). This value includes overhead. |
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. |
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. |
