# Consul Troubleshoot Proxy
|
|
|
|
Command: `consul troubleshoot proxy`
|
|
|
|
The `troubleshoot proxy` command diagnoses Consul service mesh configuration and network issues to an upstream.
|
|
|
|
## Usage
|
|
|
|
Usage: `consul troubleshoot proxy (-upstream-ip <ip>|-upstream-envoy-id <envoy-id>) [options]`
|
|
This command requires `-envoy-admin-endpoint` or `-upstream-ip` to specify the upstream.
|
|
|
|
#### Command Options
|
|
|
|
- `-envoy-admin-endpoint=<value>` - Envoy admin endpoint address for the local Envoy instance.
|
|
Defaults to `127.0.0.1:19000`.
|
|
|
|
- `-upstream-ip=<value>` - The IP address of the upstream service; Use when the upstream is reached via a transparent proxy DNS address (KubeDNS or Consul DNS)
|
|
|
|
- `-upstream-envoy-id=<value>` - The Envoy identifier of the upstream service; Use when the upstream is explicitly configured on the downstream service.
|
|
|
|
## Examples
|
|
|
|
The following example illustrates how to troubleshoot Consul service mesh configuration and network issues to an upstream from a source proxy.
|
|
|
|
```shell-session
|
|
$ consul troubleshoot proxy -upstream-ip 10.4.6.160

|
|
-> Check that your upstream service is healthy and running
|
|
-> Check that your upstream service is registered with Consul
|
|
-> Check that the upstream proxy is healthy and running
|
|
-> If you are explicitly configuring upstreams, ensure the name of the upstream is correct
|
|
```
|
|
|
|
The following example troubleshoots Consul service mesh configuration and network issues from the local Envoy instance to the given upstream.
|
|
|
|
```shell-session
|
|
$ consul-k8s troubleshoot proxy -upstream-envoy-id db
|
|
|
|
==> Validation

|
✓ Envoy has 0 rejected configurations
|
|
✓ Envoy has detected 0 connection failure(s)
|
|
✓ Listener for upstream "db" found
|
|
✓ Route for upstream "db" found
|
|
✓ Cluster "db.default.dc1.internal.e08fa6d6-e91e-dfe0.consul" for upstream "db" found
|
|
✓ Healthy endpoints for cluster "db.default.dc1.internal.e08fa6d6-e91e-dfe0.consul" for upstream "db" found
|
|
|
|
If you are still experiencing issues, you can:
|
|
-> Check intentions to ensure the upstream allows traffic from this source
|
|
-> If using transparent proxy, ensure DNS resolution is to the same IP you have verified here
|
|
```
