Just had to debug yum returning a 503 on a server deep in a private network, but curl worked fine. Was able to use tshark and pipe it to my local wireshark and re-assemble the HTTP request that finally told me it was blocked by the internet gateway and who to email!

Here is the command that piped in realtime the tshark dump to my local wireshark GUI. Don't worry about the CLI filter because we can just use display filters to get what we want. Then find a GET packet, right click and "Follow" > TCP||HTTP Stream

ssh user@host 'sudo /usr/sbin/tshark -i eth0 -f "port !22" -w -' | wireshark -k -i -

Ahh, the only reason this worked was because the URL was http. Need to figure out how to do https now.

It isn't as easy as setting some ENV vars...

If you have an interactive TTY (local dev testing)
Generate a boto config, will prompt for access key ID and secret access token This will add gs_secret_access_key and gs_access_key_id and save to ~/.boto.

gsutil config -a

If you don't have an interactive TTY (CI/automation)

The docs are here but don't specify this level of detail, I found this through trial/error: https://prometheus.io/docs/prometheus/latest/configuration/configuration/#http_config

Also see, prometheus/prometheus#12924.

Set your access policy up and create a token for it at https://grafana.com/orgs/{{ORG_NAME}}/access-policies
Get your QUERY_ENDPOINT + INSTANCE_ID from https://grafana.com/orgs/{{ORG_NAME}}/members, then click your stack on the left, https://grafana.com/orgs/hedera/stacks/{{STACK_ID}}, then click Prometheus and scroll down to get your Instance ID (https://grafana.com/orgs/hedera/hosted-metrics/{{USERNAME/INSTANCE_ID}}
Then create a file with the creds, e.g. .promtool-http-config.yml with the below format:
```
authorization:
```
