I just installed timelion but no data is shown when I try to draw metrics. Is not my first time using timelion and I did not change any conf file, the datasource index is "_all". Nothing shows.
I then enabled the initial tutorial of timelion on kibana and added the proper timestamp field to the config file, still:
"Could not validate elasticsearch config: Unknown error. "
And nothing shows. Any ideas? Permissions look ok to me. I even gave 777 permissions as a try, without a change.
