PowerScale Metrics
This section outlines the metrics collected by the Container Storage Modules (CSM) Observability module for PowerScale. The Grafana reference dashboards for PowerScale metrics can be uploaded to your Grafana instance.
I/O Performance Metrics
Storage system I/O performance metrics (IOPS, bandwidth) are available by default and broken down by cluster and quota.
To disable these metrics, set the performanceMetricsEnabled field to false in helm/values.yaml.
The following I/O performance metrics are available from the OpenTelemetry collector endpoint. Please see the CSM for Observability for more information on deploying and configuring the OpenTelemetry collector.
| Metric | Description |
|---|---|
| powerscale_cluster_cpu_use_rate | Average CPU usage for all nodes in the monitored cluster |
| powerscale_cluster_disk_read_operation_rate | Average rate at which the disks in the cluster servicing data read change requests |
| powerscale_cluster_disk_write_operation_rate | Average rate at which the disks in the cluster servicing data write change requests |
| powerscale_cluster_disk_throughput_read_rate_megabytes_per_second | Throughput rate of data being read from the disks in the cluster |
| powerscale_cluster_disk_throughput_write_rate_megabytes_per_second | Throughput rate of data being written to the disks in the cluster |
Storage Capacity Metrics
Provides visibility into the total, used, and available capacity for PowerScale cluster and quotas.
To disable these metrics, set the capacityMetricsEnabled field to false in helm/values.yaml.
The following storage capacity metrics are available from the OpenTelemetry collector endpoint. Please see the CSM for Observability for more information on deploying and configuring the OpenTelemetry collector.
| Metric | Description |
|---|---|
| powerscale_cluster_total_capacity_terabytes | Total cluster capacity (TB) |
| powerscale_cluster_remaining_capacity_terabytes | Total unused cluster capacity (TB) |
| powerscale_cluster_used_capacity_percentage | Percent of total cluster capacity that has been used |
| powerscale_cluster_total_hard_quota_gigabytes | Amount of total capacity allocated in all directory hard quotas |
| powerscale_cluster_total_hard_quota_percentage | Percent of total capacity allocated in all directory hard quotas |
| powerscale_volume_quota_subscribed_gigabytes | Space used of Quota for a directory (GB) |
| powerscale_volume_hard_quota_remaining_gigabytes | Unused spaced below the hard limit for a directory (GB) |
| powerscale_volume_quota_subscribed_percentage | Percentage of space used in hard limit for a directory |
| powerscale_volume_hard_quota_remaining_percentage | Percentage of the remaining space in hard limit for a directory |
