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
