I gave a look directly in the redis shell redis-cli -h localhost -p 6379 -a PASSWORD_IF_YOU_SET_ONE
It appears that each session store will have a different key which goes like that : w2p:sess:APP_NAME:SOME_ID And w2p:sess:APP_NAME:id_idx will contains a set of each unique session existings, so you would have to access this list of session id then access the actual session. You can list keys in redis with : SCAN 0 Better then KEYS that could cause lock and lot of memory usage To list the set of existing sessions in ...:id_idx you need to use smembers w2p:sess:APP_NAME:id_idx It migth help you figure out how to manage you redis sessions form python and better understand session contrib : https://github.com/web2py/web2py/blob/0d646fa5e7c731cb5c392adf6a885351e77e4903/gluon/contrib/redis_session.py Good luck Richard On Mon, Apr 9, 2018 at 12:11 AM, Lisandro <rostagnolisan...@gmail.com> wrote: > Recently I moved the sessions from the database to Redis, and I'm > wondering: is there a way to retrieve info about sessions when they are > stored in Redis? > For example, when sessions are stored in the database, you have the option > to use SQL to do some stuff like counting or deleting sessions.
