Telemetry Metric 'Identity Entity Active Partial Month' does not report by namespace

[dagen]

Describe the bug
The telemetry metric: vault.identity.entity.active.partial_month is documented such that entities are reported 'by namespace'. I am not seeing namespace designations within the telemetry data.

To Reproduce
Steps to reproduce the behavior:

1. Ensure telemetry metrics are exported to Prometheus or Cortex
2. View the metrics in Grafana

Expected behavior
Using the metric in PROMQL:
vault_identity_entity_active_partial_month{instance="t",job="<job_name>"}
I would expect to see individual metrics for each namespace.

Documentation reads: "The number of distinct entities (per namespace) that created a token during the current month"

Environment:

• Vault 1.16.5 (Enterprise)
• Vault 1.18.1
• Ubuntu 22.04

Vault server configuration file(s):

n/a
