Grafana 7, Alerting issue, error:"tsdb.HandleRequest() ... unsupported protocol scheme "influxdb"

Grafana Alerting

Hi, I have upgrade to 7 in docker. Alerts are not working anymore. I get following error messages and notifiction emails (if exception error or timeout - alert). Does anybody know whats wrong with my config? Graph itself works.I didn’t see issues earlier.

I’m using InfuxDb (working) and notification by mail. Also working otherwise I wouldn’t see lot’s of mails. But something is wrong.

Thank you!

Hi all, I assume this is a bug … I think I found the issue. I have configured the datasource Influxdb without leading “http:” … this works to display the graph but alerts are failing. Will check a while and open a bug-report (sure, my fault, but it could help others).

thanks for the hint. The case is, you are allowed to save a datasource without leading “http://” and everything will be working fine, until you decide to create alerts. Instead of error message, there will be “tsdb.HandleRequest()”

solved for me too… adding the http:// to the begin solved it completely

Wow, this just bit me as well. Definitely a bug. If not a code bug, then a UI or Documentation bug. When setting up the datasource, there is NO indication one way or another that a protocol would need to be specified.

Ouch - this got me. Adding the http:// in the data source solved it. Took a lot of tinkering around before I found this page!
