* Don't double report metrics on error When there is an error use a different function to report the metrics, in case the plugin chain handled the request the metrics are already reported. Fixes: #2717 Signed-off-by: Miek Gieben <miek@miek.nl> * Compile again Signed-off-by: Miek Gieben <miek@miek.nl>
