true	Azure metrics generator configuration for Helm charts.	products enterprise oss

By default, the metrics-generator doesn't require a backend connection unless you've enabled the local_blocks processor. The local_blocks processor is used for generating metrics from traces, which is required for TraceQL metrics When this configuration is set, the metrics-generator produces blocks and flushes them into a backend storage.

In this case, list the generator in the env var expansion configuration so the STORAGE_ACCOUNT_ACCESS_KEY has the secret value.

You can use this configuration example with Helm charts, like tempo-distributed. Replace any values in all caps with the values for your Helm deployment.
