Free software: MIT license
Features

build_time_range_query: Build an InfluxQL query for a topic and time range

Authentication
Credentials for authenticating to available EFDs are held in a special file on disk. By default, this location is ~/.lsst/notebook_auth.yaml. The file must exist and must have 006 permissions set. The format of the file is a YAML dictionary of valid EFD names. Each EFD entry should contain the username, password, and host for the EFD. Currently, my file looks like this:
lab_efd:
username: <user>
password: <passwd>
host: "test-influxdb-efd.lsst.codes"
summit_efd:
username: <user>
password: <passwd>
host: "influxdb-summit-efd.lsst.codes"Credits
This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.
