Sending error mails, even if just for critical ones, can become
overwhelming if enough users are hitting the error and log files are
typically never looked at. This is why we recommend using `Sentry

aggregates duplicate errors, captures the full stack trace and local
variables for debugging, and sends you mails based on new errors or
frequency thresholds.
To use Sentry you need to install the `raven` client with extra `flask` dependencies::
To use Sentry you need to install the `sentry-sdk` client with extra `flask` dependencies::
$ pip install raven[flask]
$ pip install sentry-sdk[flask]
And then add this to your Flask app::
from raven.contrib.flask import Sentry
sentry = Sentry(app, dsn='YOUR_DSN_HERE')
Or if you are using factories you can also init it later::
from raven.contrib.flask import Sentry
sentry = Sentry(dsn='YOUR_DSN_HERE')
def create_app():
app = Flask(__name__)
sentry.init_app(app)
...
return app
import sentry_sdk
from sentry_sdk.integrations.flask import FlaskIntegration
sentry_sdk.init('YOUR_DSN_HERE',integrations=[FlaskIntegration()])
The `YOUR_DSN_HERE` value needs to be replaced with the DSN value you get
from your Sentry installation.
Afterwards failures are automatically reported to Sentry and from there
you can receive error notifications.
After installation, failures leading to an Internal Server Error are automatically reported to
Sentry and from there you can receive error notifications. Sentry also supports
capturing custom exceptions::
import sentry_sdk
try:
throwing_function()
except Exception as e:
with sentry_sdk.push_scope() as scope:
sentry_sdk.capture_exception(e)
