PowerStore Metrics

This section outlines the metrics collected by the Container Storage Modules (CSM) Observability module for PowerStore. The Grafana reference dashboards for PowerStore metrics can be uploaded to your Grafana instance.

I/O Performance Metrics

Storage system I/O performance metrics (IOPS, bandwidth, latency) are available by default and broken down by export node and volume.

To disable these metrics, set the karaviMetricsPowerstore.volumeMetricsEnabled 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
powerstore_volume_read_bw_megabytes_per_second The volume read bandwidth (MB/s)
powerstore_volume_write_bw_megabytes_per_second The volume write bandwidth (MB/s)
powerstore_volume_read_latency_milliseconds The time (in ms) to complete read operations to a volume
powerstore_volume_write_latency_milliseconds The time (in ms) to complete write operations to a volume
powerstore_volume_read_iops_per_second The number of read operations performed against a volume (per second)
powerstore_volume_write_iops_per_second The number of write operations performed against a volume (per second)
powerstore_filesystem_read_bw_megabytes_per_second The filesystem read bandwidth MB/s
powerstore_filesystem_write_bw_megabytes_per_second The filesystem write bandwidth (MB/s)
powerstore_filesystem_read_iops_per_second The number of read operations performed against a filesystem (per second)
powerstore_filesystem_write_iops_per_second The number of write operations performed against a filesystem (per second)
powerstore_filesystem_read_latency_milliseconds The time (in ms) to complete read operations to a filesystem
powerstore_filesystem_write_latency_milliseconds The time (in ms) to complete write operations to a filesystem

Storage Capacity Metrics

Provides visibility into the total, used, and available capacity for a storage class and associated underlying storage construct.

To disable these metrics, set the enable_powerstore_metrics 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
powerstore_array_logical_provisioned_megabytes Total provisioned logical storage on a given array managed by CSI driver
powerstore_array_logical_used_megabytes Total used logical storage on a given array
powerstore_storage_class_logical_provisioned_megabytes Total provisioned logical storage for a given storage class
powerstore_storage_class_logical_used_megabytes Total used logical storage for a given storage class
powerstore_volume_logical_provisioned_megabytes Logical provisioned storage for a volume
powerstore_volume_logical_used_megabytes Logical used storage for a volume
powerstore_filesystem_logical_provisioned_megabytes Logical provisioned storage for a filesystem
powerstore_filesystem_logical_used_megabytes Logical used storage for a filesystem
