# Google Cloud PubSub Output Plugin
|
|
|
|
The GCP PubSub plugin publishes metrics to a [Google Cloud PubSub][pubsub] topic
|
|
as one of the supported [output data formats][].
|
|
|
|
|
|
### Configuration
|
|
|
|
This section contains the default TOML to configure the plugin. You can
|
|
generate it using `telegraf --usage cloud_pubsub`.
|
|
|
|
```toml
|
|

|
|
## the given PubSub topic.

|
|
