I am looking for a way to filter by dimensions and include their name in mstats result so that down the line I can have charts per metric and dimension. What is the way of referencing custom dimensions?
I'm not really sure what you want to accomplish directly.
But if you use mstats like this:
| mstats latest(_value) AS last_value WHERE index="my_metrics" metric_name="*" by custom_dimension, metric_name
You are able to use metric_name as well as the custom_dimension field after this command. As well as metric_name and the values of all the metrics.
hope that helps.
Can you provide some sample data?
