You've deployed Vault in your production environment and are curious to understand metrics on your Vault cluster, such as the number of writes to the backend, the status of WALs, and the seal status. What feature would you configure in order to view these metrics?
- audit device
- telemetry
- nothing to configure, these are available in the Vault log found on the OS
- enable logs for each individual secrets engines
Answer(s): B
Explanation:
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. This telemetry information can be used for debugging or otherwise getting a better view of what Vault is doing.
Telemetry information can be streamed directly from Vault to a range of metrics aggregation solutions as described in the telemetry Stanza documentation.
