Core system telemetry
Core system telemetry provides information about the operational health of your Vault instance.
Default metrics

| counter | number | Number of ignored request errors observed by the request limiter |
Ignored request errors result from early request cancellation. These errors are discarded from request limiter measurements to prevent skewing of latency measurements.
Rollback metrics
By default, Vault does not separate rollback metrics by mountpoint. To enable
explictly named metrics for mountpoints, enable the
add_mount_point_rollback_metrics
option in your telemetry configuration stanza.
If you enable named metrics for mountpoints, the metric name converts forward
slashes (/) in mount names to dashes (-). For example, if you have the
auth/token backend configured and mountpoint names enabled for telemetry,
the corresponding mount point metric string is auth-token.

convert forward slashes (/) in mount names to dashes (-). For example, if
you have the auth/token backend configured, the corresponding mount point
metric string is auth-token
By default, Vault does not separate rollback metrics by mountpoint. To enable
explictly named metrics for mountpoints, enable the
add_mount_point_rollback_metrics
option in your telemetry configuration stanza.
