Dashboard query retuning no data

What Grafana version and what operating system are you using?

  • I am running Grafana v6.7.2

  • What are you trying to achieve?
    I am attempting to query a network switch

  • How are you trying to achieve it?
    I have a collectd.d file that I have update with the snmpv3 information and I restarted the services

  • What happened?
    I performed an snmp walk and I was able to see all of the information however when I created my dashboard there my queries are returning nothing. I have devices in the same subnet with similar configuration and they are polling fine.

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
    I am not seeing any error messages in the UI however when I checked the logs I see the below error:
    grafana.net/d/VernZPMZk/sw01?panelId=11&edit&fullscreen&orgId=1" error=“http: proxy error: unsupported protocol scheme “””
    t=2021-10-22T22:26:24+0000 lvl=info msg=“Request Completed” logger=context userId=17 orgId=1 uname=user method=GET path=/api/datasources/proxy/7/query status=502 remote_addr=[::1] time_ms=1 size=0 referer=“https://grafana.net/d/VernZPMZk/sw01?panelId=11&edit&fullscreen&orgId=1

What data source are you using? “unsupported protocol scheme” is usually an incorrect url that is missing http:// or https:// at the start.

See this issue for an example of someone with the same problem: http: proxy error: unsupported protocol scheme "" · Issue #14459 · grafana/grafana · GitHub

I have change it from Https to http and it has not resolved the issue. I am not getting any error beyond no data on the grafana ui. I am only seeing this error in the server logs in cli. When I do an snmpwalk it is successful.
