Mimirtool analyze subcommand flags are not enough to get desired output

[sami-ul-islam]

Hi
I am trying to run a command mimirtool analyze ruler --address=https://mimir.ops.com --id $MIMIR_USER --key $MIMIR_PASSWORD
INFO[0000] log level set to debug
DEBU[0000] New Mimir client created address="https://mimir.ops.com" id=mimir_id
DEBU[0000] sending request to Grafana Mimir API method=GET url="https://mimir.ops.com/prometheus/config/v1/rules"
DEBU[0001] checking response status="200 OK"
Expected output:
{ "metricsUsed": [ "apiserver_request_duration_seconds_bucket", "container_cpu_usage_seconds_total", "scheduler_scheduling_algorithm_duration_seconds_bucket" ], "ruleGroups": [ { "namspace": "prometheus_rules", "name": "kube-apiserver.rules", "metrics": [ "apiserver_request_duration_seconds_bucket", "apiserver_request_duration_seconds_count", "apiserver_request_total" ], "parse_errors": null } ] }

Actual Output:
{ "metricsUsed": null, "ruleGroups": null }

The reason for this, there is no option to specify tenant id for the above mimirtool analyze ruler command.
Without tenant id:
curl -u "$MIMIR_USER:$MIMIR_PASSWORD" https://mimir.ops.com/prometheus/config/v1/rules {}

With tenant id:
it is able to browse the rules and gives me the list of all the rule i have in mimir with below command:
curl -H "X-Scope-OrgID: mimir-monitoring" -u "$MIMIR_USER:$MIMIR_PASSWORD" https://mimir.ops.com//prometheus/config/v1/rules

So currently supported options doesn't seem enough and they are also quite confusing https://grafana.com/docs/mimir/latest/manage/tools/mimirtool/#ruler
Environment variable Flag Description
MIMIR_ADDRESS --address Sets the address of the Prometheus instance.
MIMIR_TENANT_ID --id Sets the basic auth username. If you’re using Grafana Cloud, this variable is your instance ID.
MIMIR_API_KEY --key Sets the basic auth password. If you’re using Grafana Cloud, this variable is your API key.
-output Sets the output file path, which by default is metrics-in-ruler.json.

The flag --id is quite confusing as i need to provide both username and tenant id in order to get desired result but seems like i can only specify one which results in {} output.
How can i specify tenant id as well along with mimir username and password?
