Using Stackdriver Logging in App Engine apps
Present only if the app uses the Users API and the user is logged in. This value is the "nickname" portion of the Google Account, for example, if the Google Account is test example. First line of the request, containing method, path, and HTTP version. If there is no referrer, the log contains no path, but only -.
Example referrer path: Identifies the browser and operating system to the web server. The hostname used by the client to connect to the App Engine application. Total clock time in milliseconds spent by App Engine on the request. This time duration does not include time spent between the client and the server running the instance of your application. CPU milliseconds required to fulfill the request.

This is the number of milliseconds spent by the CPU actually executing your application code, expressed in terms of a baseline 1. If the CPU actually used is faster than the baseline, the CPU milliseconds can be larger than the actual clock time defined above. Only present if the instance shut down after getting the request. The exit codes are not documented since they are primarily intended to help Google spot and fix issues.
Estimated cost of requests just like this one, in USD. The name of the task queue used.
Only present if request used a task queue. The name of the task executed in the task queue for this request. Only present if the request resulted in the queuing of a task. Only present if a request spent some time in a pending queue. Only present if the request is a loading request. This means an instance had to be started up.
Ideally, your instances should be up and healthy for as long as possible, serving large numbers of requests before being recycled and needing to be started again. In your web browser, go to http: After you update your app, you can redeploy the updated version by entering the same command as when you first deployed the app as well as specifying the same project ID and version. This overwrites the currently deployed app. If you specify a different version string in the updated command line, the new deployment creates a new version of your app and promotes it to be the currently serving version.
To delete an app version: Go to the Versions page. For complete information about cleaning up billable resources, see the Cleaning up section in the final step of this tutorial. As the Bookshelf app runs, it writes logging data that is collected and made available in the GCP Console. You can use the log monitoring tools in the GCP Console to analyze the logs directly. If you want more detailed analysis, you can use the GCP Console to stream or import the app's logs into BigQuery or export them to a Cloud Storage bucket. The following diagram shows how the app handles logging when deployed to the App Engine standard environment.
There are many Java logging packages that are compatible with the App Engine standard environment.
This sample uses java. Each class needs a Logger instantiated as follows:. The log method takes a level value and a string. See the Java Level for more information. Possible values for the level are:.

It is also possible to log using one of the short-cut methods: Logging levels, which are often set from properties files, can also be set and changed in logging. When the sample app runs in the App Engine standard environment, app logs are automatically collected by Stackdriver Logging and available to view, search, and export in the logs viewer in the GCP Console.

The easiest way to eliminate billing is to delete the project you created for the tutorial. To delete the project: Go to the Projects page. If you don't want to delete your project, you can reduce costs by deleting the non-default versions of your app. To delete a Cloud Storage bucket: Go to the Cloud Storage browser.
