Grafana and Docker (open-nti)

  1. If a make some new dashboards, they are gone after boot of the server. Why?
  2. Where is the custom.ini file stored ? And how to “activate” the changes?
  3. Error when sending alert mail:

t=2019-02-05T14:47:37+0100 lvl=eror msg=“Failed to send alert notification email” logger=alerting.notifier.email error=“dial tcp xx.xx.xx.xx:25: i/o timeout”

t=2019-02-05T14:47:37+0100 lvl=eror msg=“Request Completed” logger=context userId=1 orgId=1 uname=admin method=POST path=/api/alert-notifications/test status=500 remote_addr=172.16.240.11 time_ms=5006 size=48 referer=http://xx.xx.xx.xx/alerting/notification/1/edit

From where do grafana get remote_addr=172.16.240.11?
