PowerMax Metrics
This section outlines the metrics collected by the Container Storage Modules (CSM) Observability module for PowerMax. The Grafana reference dashboards for PowerMax metrics can be uploaded to your Grafana instance.
Prerequisites
- Unisphere user credentials must have PERF_MONITOR permissions.
- Ensure time synchronization for Kubernetes cluster and PowerMax Unisphere by using Network Time Protocol (NTP).
I/O Performance Metrics
Storage system I/O performance metrics (IOPS, bandwidth, latency) are available by default and broken down by storage group and volume.
To disable these metrics, set the performanceMetricsEnabled field under karaviMetricsPowerMax 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 |
|---|---|
| powermax_storage_group_read_bw_megabytes_per_second | The storage group read bandwidth (MB/s) |
| powermax_storage_group_write_bw_megabytes_per_second | The storage group write bandwidth (MB/s) |
| powermax_storage_group_read_latency_milliseconds | The time (in ms) to complete read operations within PowerMax system by the storage group |
| powermax_storage_group_write_latency_milliseconds | The time (in ms) to complete write operations within PowerMax system by the storage group |
| powermax_storage_group_read_iops_per_second | The number of read operations performed by a storage group (per second) |
| powermax_storage_group_write_iops_per_second | The number of write operations performed by a storage group (per second) |
| powermax_storage_group_average_io_size_megabytes_per_second | The storage group average IO sizes (MB/s) |
| powermax_volume_read_bw_megabytes_per_second | The volume read bandwidth (MB/s) |
| powermax_volume_write_bw_megabytes_per_second | The volume write bandwidth (MB/s) |
| powermax_volume_read_latency_milliseconds | The time (in ms) to complete read operations to a volume |
| powermax_volume_write_latency_milliseconds | The time (in ms) to complete write operations to a volume |
| powermax_volume_read_iops_per_second | The number of read operations performed against a volume (per second) |
| powermax_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 capacityMetricsEnabled field under karaviMetricsPowerMax 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 |
|---|---|
| powermax_storage_class_total_capacity_gigabytes | Total capacity for a given storage class (GB) |
| powermax_storage_class_used_capacity_gigabytes | Total used capacity for a given storage class (GB) |
| powermax_storage_class_used_capacity_percentage | Used capacity of a storage class in percent |
| powermax_array_total_capacity_gigabytes | Total capacity on a given array managed by CSI driver (GB) |
| powermax_array_used_capacity_gigabytes | Total used capacity on a given array managed by CSI driver (GB) |
| powermax_array_used_capacity_percentage | Total used capacity on a given array managed by CSI driver in percent |
| powermax_storage_group_total_capacity_gigabytes | Total capacity for a given storage group (GB) |
| powermax_storage_group_used_capacity_gigabytes | Total used capacity for a given storage group (GB) |
| powermax_storage_group_used_capacity_percentage | Used capacity of a storage group in percent |
| powermax_srp_total_capacity_gigabytes | Total capacity of the storage resource pool in GB managed by CSI driver |
| powermax_srp_used_capacity_gigabytes | Used capacity of a storage resource pool in GB managed by CSI driver |
| powermax_srp_used_capacity_percentage | Used capacity of a storage resource pool in percent |
| powermax_volume_total_capacity_gigabytes | Total capacity of the volume in GB |
| powermax_volume_used_capacity_gigabytes | Used capacity of a volume in GB |
| powermax_volume_used_capacity_percentage | Used capacity of a volume in percent |
