Homer still tries to connect to Grafana even though it should be disabled

[inmula]

I just upgraded homer from 1.4.37 to 1.4.50. When I try to access the web interface after updating I see the following error:

{"message":"remote http://127.0.0.1:3000 unreachable, could not forward: dial tcp 127.0.0.1:3000: connect: connection refused"}

My webapp_config.json contains the following configuration for Grafana:

  "grafana_config": {
    "enable": false,
    "help": "Settings for Grafana",
    "host": "http://127.0.0.1:3000",
    "path": "",
    "proxy_check": "simple",
    "proxy_control": false,
    "token": ""
  },

Since enable is set to false, it shouldn't try to connect to Grafana.

Downgrading homer-app to 1.4.37 fixes the issue.

Your report is appreciated. Please star this repository to motivate its developers! :star:

[adubovikov]

can you set host to = "" ? It will disable it completely.

[adubovikov]

also, please check if you have grafana hosts in your UI Settings. It should be removed.

[inmula]

Thanks for the quick reply, when I set the host to "" the error changes to:

{"message":"remote  unreachable, could not forward: unsupported protocol scheme \"\""}

In the 1.4.37 web UI I don't see any Grafana related settings in the web-interface. I can't access the UI in 1.4.50 though.

Let us check

@inmula sorry, do you have the grafana widget on main dashboard ? I couln't reproduce it

[inmula]

@adubovikov I don't have the grafana widget on my dashboard. I just removed all tables in the homer_config database and re-created them using ./homer-app -create-table-db-config and ./homer-app -populate-table-db-config and I still get the error when trying to access the web-interface (I don't even get to the login page).

I just tried version 1.4.51 and I still run into the same error.

[adubovikov]

@rlaager it was fixed in homer-app_1.4.52

[inmula]

Hello, I tried version 1.4.53 and it seems to have resolved the issue with Grafana too. Thanks for your help!
