Tracing Azure Functions can be done using the epsagon.azure_wrapper decorator.

For example:

import azure.functions as func
import epsagon
epsagon.init(
    token='epsagon-token',
    app_name='app-name-stage',
    metadata_only=False,
)

@epsagon.azure_wrapper
def main(req):
    return func.HttpResponse('Success')
