Google Cloud Logging Plugin

Enterprise Feature

Custom logging is limited to Enterprise plans. If you want to test custom logging, contact sales@zuplo.com to have an enterprise trial enabled.

Setup#

The GCP Log plugin enables pushing logs to your GCP project.

Before you can use this plugin, you will need to create a GCP Service account that grants your Zuplo API to write logs. Create a new GCP Service account and give it the Logs Writer (roles/logging.logWriter) permission. Create a key for the service account in JSON format.

After you have downloaded the JSON formatted service account, save it as a secret environment variable in your Zuplo project.

modules/zuplo.runtime.ts
import { RuntimeExtensions, GoogleCloudLoggingPlugin, environment, } from "@zuplo/runtime"; export function runtimeInit(runtime: RuntimeExtensions) { runtime.addPlugin( new GoogleCloudLoggingPlugin({ logName: "projects/my-project/logs/my-api", serviceAccountJson: environment.GCP_SERVICE_ACCOUNT, }), ); }

Standard Fields#

Every log entry will have a timestamp and a jsonPayload object. The value of the jsonPayload contains the text or objects passed into the log.

Default fields are:

  • severity - The level of the log, i.e. ERROR, INFO, etc.
  • requestId - The UUID of the request (the value of the zp-rid header)
  • environmentType - Where the Zuplo API is running. Values are edge, working-copy, or local
  • environmentStage - If the environment is working-copy, preview, or production
  • atomic_counter - An atomic number that is used to order logs that have the same timestamp
  • environment - The environment name of the Zuplo API
  • rayId - The Cloudflare RayID of the request (for edge deployed environments)

Log Format#

The shape of the logs sent from Zuplo will be in the following format. The messages passed into the log function will be sent as an array on allMessages. The first string message will be set as the jsonPayload.message field - this makes it easier to read the logs in Google's Log Explorer.

{ "insertId": "1sxlp0rg113cy7s", "jsonPayload": { "message": "Request received '/hello'", "allMessages": [ "Request received '/hello'", { "route": "/hello", "method": "GET", "hostname": "my-project-main-db51244.zuplo.app", "url": "/hello" } ] }, "resource": { "type": "global", "labels": { "project_id": "my-project" } }, "timestamp": "2024-02-27T22:18:48.885Z", "severity": "DEBUG", "labels": { "environmentStage": "production", "logOwner": "user", "rayId": "85c3ce476cfc399a", "environmentType": "edge", "buildId": "365cd2da-6156-48c8-b142-4e5aa4a7e6d7", "requestId": "1482d01b-9d74-4cff-a0e3-e1adda46354f", "loggingId": "nate-test::my-project::main::main::db51244", "source": "request", "environment": "my-project-main-db51244" }, "logName": "projects/my-project/logs/my-project", "trace": "projects/my-project/traces/1482d01b-9d74-4cff-a0e3-e1adda46354f", "receiveTimestamp": "2024-02-27T22:18:48.921958689Z" }
