» Telemetry

The Vault server process collects various runtime metrics about the performance of different libraries and subsystems. These metrics are aggregated on a ten second interval and are retained for one minute.

To view the raw data, you must send a signal to the Vault process: on Unix-style operating systems, this is USR1 while on Windows it is BREAK. When the Vault process receives this signal it will dump the current telemetry information to the process's stderr.

This telemetry information can be used for debugging or otherwise getting a better view of what Vault is doing.

Telemetry information can also be streamed directly from Vault to a range of metrics aggregation solutions as described in the telemetry Stanza documentation.

The following is an example telemetry dump snippet:

You'll note that log entries are prefixed with the metric type as follows:

  • [C] is a counter
  • [G] is a gauge
  • [S] is a summary

The following sections describe available Vault metrics. The metrics interval can be assumed to be 10 seconds when manually triggering metrics output using the above described signals.

Any non-zero value here indicates that there was a failure to make an audit log request to any of the configured audit log devices; when Vault cannot log to any of the configured audit log devices it ceases all user operations, and you should begin troubleshooting the audit log devices immediately if this metric continually increases. failures counter
vault.audit.log_response_failure Number of audit log response failures. NOTE: This is a particularly important metric. Any non-zero value here indicates that there was a failure to receive a response to a request made to one of the configured audit log devices; when Vault cannot log to any of the configured audit log devices it ceases all user operations, and you should begin troubleshooting the audit log devices immediately if this metric continually increases. failures counter

NOTE: In addition, there are audit metrics for each enabled audit device represented as vault.audit.<type>.log_request. For example, if a file audit device is enabled, its metrics would be vault.audit.file.log_request and vault.audit.file.log_response .
