Please read the [sink documentation](https://vector.dev/docs/reference/configuration/sinks/) for your sink of choice to configure the sink as desired.
##### Configuring the app label
Logs shipped by vector include the label `com.dokku.app-name`, which is an alias for the app name. This can be changed via the `app-label-alias` logs property with the `logs:set` command. Specifying a new alias will reload any running vector container.
```shell
# setting the sink value in quotes is encouraged to avoid
# issues with ampersand encoding in shell commands
dokku logs:set node-js-app app-label-alias "app-name"
```
An alias may be removed by setting an empty value, which will also reload the running vector container.
```shell
dokku logs:set node-js-app app-label-alias
```
Only one alias may be specified on a per-app basis at a given time.
App label aliases can also be specified globally by specifying the `--global` flag to `logs:set` with no app name specified:
```shell
dokku logs:set --global app-label-alias "app-name"
```
As with app-specific label alias settings, the global value may also be cleared by setting no value.
```shell
dokku logs:set --global app-label-alias
```
