 ===== Configuration =====
+<note>Example configuration is not runable, all the ''meter'' are deactivated</note>
 The vzlogger configuration is done with a file containing JSON encoded settings. General settings also can be set via the [[#command_line_parameters|command line]]. You must have at least one meter in your configuration. Channels are optional. A meter can have more channels. Ex. if you want to log to multiple middleware servers.

+===== Exit-Codes =====
+For diagnostics usally the logfile is used because of vzlogger running under control of systemd. In cases this is not possible exit-codes will be shown.\\
+E.g. calling ''systemctl status vzlogger'' shows something like: ''Main process exited, code=exited, status=1/FAILURE''
