 | `vault.expire.leases.by_expiration` (cluster,gauge,expiring,namespace)                          | Number of leases set to expire, grouped by a time interval. This time interval and total number of time intervals are configurable via `lease_metrics_epsilon` and `num_lease_metrics_buckets` in the telemetry stanza of a vault server configuration. The default values for these are `1hr` and `168` respectively, so the metric will report the number of leases that will expire each hour from the current time to a week from the current time. One can additionally group lease expiration by namespace by setting `add_lease_metrics_namespace_labels` to `true` in the config file (default is `false`). | leases   | gauge   |
