PowerFlex Metrics
This section outlines the metrics collected by the Container Storage Modules (CSM) Observability module for PowerFlex. The Grafana reference dashboards for PowerFlex 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 sdc_metrics_enabled 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 |
|---|---|
| powerflex_export_node_read_bw_megabytes_per_second | The export node read bandwidth (MB/s) within PowerFlex system |
| powerflex_export_node_write_bw_megabytes_per_second | The export node write bandwidth (MB/s) |
| powerflex_export_node_read_latency_milliseconds | The time (in ms) to complete read operations within PowerFlex system by the export node |
| powerflex_export_node_write_latency_milliseconds | The time (in ms) to complete write operations within PowerFlex system by the export host |
| powerflex_export_node_read_iops_per_second | The number of read operations performed by an export node (per second) |
| powerflex_export_node_write_iops_per_second | The number of write operations performed by an export node (per second) |
| powerflex_volume_read_bw_megabytes_per_second | The volume read bandwidth (MB/s) |
| powerflex_volume_write_bw_megabytes_per_second | The volume write bandwidth (MB/s) |
| powerflex_volume_read_latency_milliseconds | The time (in ms) to complete read operations to a volume |
| powerflex_volume_write_latency_milliseconds | The time (in ms) to complete write operations to a volume |
| powerflex_volume_read_iops_per_second | The number of read operations performed against a volume (per second) |
| powerflex_volume_write_iops_per_second | The number of write operations performed against a volume (per second) |
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 storage_class_pool_metrics_enabled 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 |
|---|---|
| powerflex_storage_pool_total_logical_capacity_gigabytes | The logical capacity (size) of a storage pool (GB) |
| powerflex_storage_pool_logical_capacity_available_gigabytes | The capacity available for use (GB) |
| powerflex_storage_pool_logical_capacity_in_use_gigabytes | The logical capacity of a storage pool in use (GB) |
| powerflex_storage_pool_logical_provisioned_gigabytes | The total size of volumes (thick and thin) provisioned in a storage pool (GB) |
