Requesting description for last activity response parameter.

[Praveen Krishnamoorthy]

Hi,

I posting this question, to get clarification on the response parameter send by the jupyterhub server while sending REST api request to fetch the list of users.

REST API Call : curl -XGET -s -k https://localhost:9443/hub/api/users -H "Authorization: token $apitoken" | jq .

Response :

{

  "kind": "user",

  "name": "jovyan",

  "admin": true,

  "groups": [],

  "server": "/user/jovyan/",

  "pending": null,

  "created": "2019-02-16T20:58:41.009053Z",

  "last_activity": "2019-02-16T23:59:34.296819Z",

  "servers": {

    "": {

      "name": "",

      "last_activity": "2019-02-16T23:50:37.249000Z",

      "started": "2019-02-16T21:12:55.161109Z",

      "pending": null,

      "ready": true,

      "state": {

        "pid": 72

      },

      "url": "/user/jovyan/",

      "progress_url": "/hub/api/users/jovyan/server/progress"

    }

  },

  "auth_state": null

}

Could anyone say me the description/difference between the last activity 2 parameter(highlighted in red) ?

Thanks,

Praveen.

Hello Praveen,

I'd say one is the last activity of the user in general, the other is the last activity of that particular server of the user.

The REST API looks as if a user can start multiple servers:

https://jupyterhub.readthedocs.io/en/stable/_static/rest-api/index.html

So the existing servers may have different last activity times. And if the user deletes a server, that would update the user's last activity, while leaving the timestamps for the remaining servers unchanged.

Hope that helps,

  Roland
