     1  # Enabling Envoy Debug Logging
     2  
     3  The `envoy` command has a `--log-level` [flag][1] that can be useful for debugging.
     4  By default, it's set to `info`.
     5  To change it to `debug`, edit the `envoy` DaemonSet in the `projectcontour` namespace and replace the `--log-level info` flag with `--log-level debug`.
     6  Setting the Envoy log level to `debug` can be particilarly useful for debugging TLS connection failures.
