# File Audit Device
|
|
|
|
The `file` audit device writes audit logs to a file. This is a very simple audit
|
|
device: it appends logs to a file.
|
|
|
|
The device does not currently assist with any log rotation. There are very
|
|
stable and feature-filled log rotation tools already, so we recommend using
|
|
existing tools.
|
|
|
|
Sending a `SIGHUP` to the Vault process will cause `file` audit devices to close
|
|
and re-open their underlying file, which can assist with log rotation needs.
|
|
|
|
## Examples
|
|
|
|
Enable at the default path:
|
|
|
|
```shell-session
|
|
$ vault audit enable file file_path=/var/log/vault_audit.log
|
|
```
|
|
|
|
Enable at a different path. It is possible to enable multiple copies of an audit
|
|
device:
|
|
|
|
```shell-session
|
|
$ vault audit enable -path="vault_audit_1" file file_path=/home/user/vault_audit.log
|
|
```
|
|
|
|
Enable logs on stdout. This is useful when running in a container:
|
|
|
|
```shell-session
|
|
$ vault audit enable file file_path=stdout
|
|
```
|
|
|
|
## Configuration
|
|
|
|
Note the difference between `audit enable` command options and the `file` backend
|
|
configuration options. Use `vault audit enable -help` to see the command options.
|
|
Following are the configuration options available for the backend.
|
|
|
|
## Configuration
|
|
|
|
- `file_path` `(string: <required>)` - The path to where the audit log will be
|
|
written. If a file already exists at the given path, the audit backend will
|
|
append to it. There are some special keywords:
|
|
|
|
- `stdout` writes the audit log to standard output
|
|
|
|
- `discard` writes output (useful in testing scenarios)
|
|
|
|
- `log_raw` `(bool: false)` - If enabled, logs the security sensitive
|
|
information without hashing, in the raw format.
|
|
|
|
- `hmac_accessor` `(bool: true)` - If enabled, enables the hashing of token
|
|
accessor.
|
|
|
|
- `mode` `(string: "0600")` - A string containing an octal number representing
|
|
the bit pattern for the file mode, similar to `chmod`. Set to `"0000"` to
|
|
prevent Vault from modifying the file mode.
|
|
|
|
- `format` `(string: "json")` - Allows selecting the output format. Valid values
|
|
are `"json"` and `"jsonx"`, which formats the normal log entries as XML.
|
|
|
|
- `prefix` `(string: "")` - A customizable string prefix to write before the
|
|
actual log line.
|
|
|
|
## Log File Rotation
|
|
|
|
To properly rotate Vault File Audit Device log files on BSD, Darwin, or Linux-based Vault servers, it is important that you configure your log rotation software to send the `vault` process a signal hang up / `SIGHUP` after each rotation of the log file.
