Talisker provides out-of-the-box integration with sentry.

Specifically, Talisker adds:

  • some default configuration of the sentry client

  • handle WSGI errors

  • sentry error log handler (for logged exception messages)

  • log message, sql and http call breadcrumbs

  • sentry integration with flask, django, and celery

To get the current sentry client, simply use:


Error Data

Talisker configures sentry breadcrumbs for log messages at INFO or higher level. It also adds the request id as a tag to the sentry message.

If you want to add some custom error context, you can use the client above as you would use the sentry client as normal. For example:

client = talisker.sentry.get_client()
client.context.merge({'tags': my_tags})

Sentry Configuration

Talisker uses the default SENTRY_DSN env var to configure sentry by default. Simply setting this will enable sentry for wsgi and logging.

In addition, Talisker configures the sentry client by default as follows:

  • sets install_logging_hook=False, as Talisker handles it

  • sets release to the current revision

  • sets hook_libraries=[], disabling breadcrumbs for request/httplib

  • sets environment to TALISKER_ENV envvar

  • sets name to TALISKER_UNIT envvar

  • sets site to TALISKER_DOMAIN envvar

  • ensures the RemovePostDataProcessor, SanitizePasswordsProcessor, and RemoveStackLocalsProcessor processors are always included, to be safe by default.

If you are using Talisker’s Flask or Django integration, you can configure your sentry client further via the usual config methods for those frameworks.

If you wish to manually configure the sentry client, use the following:


This will reconfigure and reset the sentry client used by the wsgi middleware and logging handler that Talisker sets up.

If you want to set your own client instance, do:


Whichever way you wish to configure sentry, talisker will honour your configuration except for 2 things

  1. install_logging_hook will always be set to false, or else you’ll get duplicate exceptions logged to sentry.

  2. the processors will always include the base 3, although you can add more. If you really need to remove the default processors, you can modify the list at talisker.sentry.default_processors and then call talisker.sentry.set_client().
