Using Cloud Error Reporting

After configuring your environment, create a Client

from google.cloud import error_reporting
client = error_reporting.Client()

or pass in credentials and project explicitly

from google.cloud import error_reporting
client = error_reporting.Client(project='my-project', credentials=creds)

Error Reporting associates errors with a service, which is an identifier for an executable, App Engine service, or job. The default service is "python", but a default can be specified for the client on construction time. You can also optionally specify a version for that service, which defaults to "default."

from google.cloud import error_reporting
client = error_reporting.Client(
 project='my-project', service="login_service", version="0.1.0")

Reporting an exception

Report a stacktrace to Cloud Error Reporting after an exception:

from google.cloud import error_reporting
client = error_reporting.Client()
try:
 raise NameError
except Exception:
 client.report_exception()

By default, the client will report the error using the service specified in the client’s constructor, or the default service of "python".

The user and HTTP context can also be included in the exception. The HTTP context can be constructed using google.cloud.error_reporting.HTTPContext. This will be used by Cloud Error Reporting to help group exceptions.

from google.cloud import error_reporting
client = error_reporting.Client()
user = 'example@gmail.com'
http_context = error_reporting.HTTPContext(
 method='GET', url='/', user_agent='test agent',
 referrer='example.com', response_status_code=500,
 remote_ip='1.2.3.4')
try:
 raise NameError
except Exception:
 client.report_exception(http_context=http_context, user=user))

An automatic helper to build the HTTP Context from a Flask (Werkzeug) request object is provided.

from google.cloud.error_reporting import build_flask_context
@app.errorhandler(HTTPException)
def handle_error(exc):
 client.report_exception(
 http_context=build_flask_context(request))
 # rest of error response code here

Reporting an error without an exception

Errors can also be reported to Cloud Error Reporting outside the context of an exception. The library will include the file path, function name, and line number of the location where the error was reported.

from google.cloud import error_reporting
client = error_reporting.Client()
client.report("Found an error!")

As with reporting an exception, the user and HTTP context can be provided:

from google.cloud import error_reporting
client = error_reporting.Client()
user = 'example@gmail.com'
http_context = error_reporting.HTTPContext(
 method='GET', url='/', user_agent='test agent',
 referrer='example.com', response_status_code=500,
 remote_ip='1.2.3.4')
client.report(
 "Found an error!", http_context=http_context, user=user))
