/sys/monitor

The /sys/monitor endpoint is used to receive streaming logs from the Vault server.

If Vault is emitting log messages faster than a receiver can process them, then some log lines will be dropped.

Monitor system logs

This endpoint streams logs back to the client from Vault. Note that unlike most API endpoints in Vault, this one does not return JSON by default. This will send back data in whatever log format Vault has been configured with. By default, this is text.

Parameters

• log_level (string: "info") – Specifies the log level to use when streaming logs. This defaults to info if not specified.
