  I tried to configure Redis as session provider.

  • Include raw network request & response: get by opening Chrome Dev Tools (F12, Ctrl+Shift+I on windows, Cmd+Opt+I on Mac), go the network tab.

I'm confuse. I tried to configure redis, but the documentation is not clear.

In the configuration file your example is :
# redis: config like redis server e.g. addr=127.0.0.1:6379,pool_size=100,db=grafana

On your webiste i found this example :
redis: ex: addr=127.0.0.1:6379,pool_size=100,prefix=grafana

And in a precedent issue I saw this configuration :
provider_config = addr=1.2.3.4:5000,pool_size=100,password=SECRETS

So, what is the good syntax ?

Thanks.

Please let me know what change needs to be made to the documentation.

I think this is changed sometime ago and now the comment in the config file and the docs in our site is the same.
