What Grafana version and what operating system are you using?
-
v8.2.0 (d7f71e9eae) running in docker on Windows 10.
-
What are you trying to achieve?
Connect Jaeger as a data source after the initial install of Grafana.
- How are you trying to achieve it?
I am filling out the Jaeger data source dialog. I enter http://localhost:16686 and click on Save and Test.
- What happened?
The following is displayed in the data source screen. Jaeger: Bad Gateway. 502. Bad Gateway shown in browser
In the docker image for grafana I can see a connection refused message
t=2021-10-11T01:34:53+0000 lvl=eror msg=“Data proxy error” logger=data-proxy-log userId=1 orgId=1 uname=admin path=/api/datasources/proxy/3/api/services remote_addr=172.17.0.1 referer=http://grafana.staged-by-discourse.com/datasources/edit/xCVWnQv7k error=“http: proxy error: dial tcp 127.0.0.1:16686: connect: connection refused”
Both Jaeger and Grafana are running in docker on the same machine as I am on. All localhost. I can connect to Jaegar in the browser and I can connect to Jaegar via powershell without error on the same computer hosting the docker images.
Invoke-WebRequest -uri http://127.0.0.1:16686
I can also connect using c#
WebClient wc = new WebClient();
string data = wc.DownloadString("http://localhost:16686");
But Grafana does not seem to be able to connect to the Jaegar instance. Grafana is running on localhost on port 3000
- What did you expect to happen?
It should connect without error.
- Can you copy/paste the configuration(s) that you are having problems with?
No configuration changes made except trying to add the data source.
- Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
