Error while running app.py file Invalid URL 'None/api/v1/query': No schema supplied. Perhaps you meant http://None/api/v1/query?

Hi, I'm trying this repository on Py-3.6 but I'm getting the following error:

I'm not able to understand this error. Am I supposed to pass some values to the app.py file?

Invalid URL 'None/api/v1/query': No schema su it looks like the prometheus url wasn't properly set

[tarakshah94]

I've given it the URL of my Prometheus client which is working absolutely fine in my browser,

url for the prometheus host

prometheus_url = os.getenv("http://xx.xxx.192.109:9090/graph")

masked for obvious reasons.

and for now, since there's no authentication required I've commented this block:

any headers that need to be passed while connecting to the prometheus host

#prom_connect_headers = None
# example oath token passed as a header
#if os.getenv("FLT_PROM_ACCESS_TOKEN"):
    #prom_connect_headers = {
        #"Authorization": "bearer " + os.getenv("FLT_PROM_ACCESS_TOKEN")
    #}

And my device metrics are stored in a variable called device_metrics, so here's my list:

metrics_list = str( os.getenv( "device_metric" ) ).split(";")

[4n4nd]

prometheus_url = os.getenv("http://xx.xxx.192.109:9090/graph") so this line looking for an env variable http://xx.xxx.192.109:9090/graph. I think what you need is prometheus_url = "http://xx.xxx.192.109:9090/graph"

other than that, I don't think you need to comment out any of the configuration stuff

This solved it. I spent a good amount of time on such a silly mistake! Thanks for pointing that @4n4nd
