I am trying to set the proxy_url param on a scrape config job that uses azure_sd_configs for azure service discovery. It appears that the azure service discovery module does not respect this setting from the scrape_config block as documented here: https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config.
It is my belief after perusing the code, that the cause of the problem is this service discoverer uses https://github.com/Azure/go-autorest instead of net/http directly, thus I think the proxy_url config setting is "lost". I have proven my config works when it is in a prometheus that is *NOT* behind our corporate proxy (with no proxy_url value set atall of course), but moving the config to a prometheus instance behind the corp proxy and setting proxy_url does not work. The only symptom is after 7 minutes, an error message appears in the logs: level=error ts=2020-11-06T21:00:31.200Z caller=refresh.go:98 component="discovery manager scrape" discovery=azure msg="Unable to refresh target groups" err="could not get virtual machines: could not list virtual machines: azure.BearerAuthorizer#WithAuthorization: Failed to refresh the Token for request to https://management.azure.com/subscriptions/xxxxxx/providers/Microsoft.Compute/virtualMachines?api-version=2018-10-01: StatusCode=0 -- Original Error: adal: Failed to execute the refresh request. Error = 'Post \"https://login.microsoftonline.com/xxxxx/oauth2/token?api-version=1.0\": read tcp <ipaddresses>: read: connection reset by peer'" This is a sign that the net connection to authenticate to microsoft failed to navigate the proxy. Does anyone have any experience with this? Can anyone confirm if this is a bug? -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
