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 |
