Issue with Metric Aggregation [MetricFamilies MUST NOT be interleaved.]

[maurisource]

So I'm working with the latest version of the module in Adobe Commerce 2.4.7-p1 with Php 8.3.

I face an issue with the following metrics I tested:

TYPE magento_orders_count_total gauge

I've generated the DB with the CLI command: run_as_root:metric:collect

I processed 2 new orders state and perform the Metric Collect command again.

The problem is that the aggregated metrics at the end of file, are being discarded from Prometheus.
Shouldn't those new lines be within # TYPE magento_orders_count_total gauge ?

Hello @DavidLambauer
There's a bug in your module which fails this OpenMetrics basic principle here:
MetricFamilies MUST NOT be interleaved.

Are you able to fix it from your end?

Hey @maurisource,

thank you for your patience. We'll look at this issue and plan it internally.
