# Automatic Instrumentation | Sentry for Google Cloud Functions

When performance is enabled through `tracesSampleRate` or a `tracesSampler` function, the Sentry SDK will automatically capture spans for incoming, and outgoing HTTP requests.

Database instrumentation can be manually enabled by adding the corresponding integration to the `integrations` array in the `init` method. The following packages are supported:

* `mysql`
* `mysql2`
* `pg`
* `graphql` (including Apollo Server)
* `mongo`
* `mongoose`
* `ioredis`
* `prisma` (requires additional configuration - see [Prisma Integration](https://docs.sentry.io/platforms/javascript/guides/gcp-functions/configuration/integrations/prisma.md))

You can add the integrations as follows:

```javascript
const Sentry = require("@sentry/google-cloud-serverless");

Sentry.init({
  dsn: "___PUBLIC_DSN___",
  tracesSampleRate: 1.0,
  integrations: [
    Sentry.mysqlIntegration(),
    Sentry.mysql2Integration(),
    Sentry.pgIntegration(),
    Sentry.graphqlIntegration(),
    Sentry.mongoIntegration(),
    Sentry.mongooseIntegration(),
    Sentry.ioredisIntegration(),
  ],
});
```
