Create an API token for an admin user of the Hub:
export JPY_API_TOKEN=`jupyterhub token [admin_user]`
Run the script:
./log_activity
This fills a simple sqlite database (activity.sqlite by default) periodically with a bool value for whether each user has been seen since the last check.
The table has the form:
date (utc) | username (str) | active (bool)
The default interval is ten minutes. It should be larger than the Hub's own activity update interval, which is five minutes.
usage: log_activity [-h] [-f FILE] [--interval INTERVAL] [--hub HUB]
optional arguments:
-h, --help show this help message and exit
-f FILE, --file FILE The sqlite file where activity should be logged.
--interval INTERVAL The interval, in seconds, for polling activity. Should
be greater than Hub activity interval (5 minutes).
--hub HUB The hub's url. If no protocol is specified, http will
be assumed.
