Connects to local envoy proxy and troubleshoots service mesh communication issues.
Requires an upstream service envoy identifier.
Examples:
$ consul troubleshoot proxy -upstream foo
(explicit upstreams only)
$ consul troubleshoot proxy -upstream-envoy-id foo
(transparent proxy only)
$ consul troubleshoot proxy -upstream-ip <IP>
where 'foo' is the upstream envoy ID which
where 'foo' is the upstream envoy identifier which
can be obtained by running:
$ consul troubleshoot upstreams [options]
