Need help in querying multiple metrics at the same time

[gokul krish]

I want to run 100s of prometheus range vector queries with different metric names as well as different labels and value. I want to fetch the data for last one hour for all queries, at once

For example:

calls_per_min{account="se", service="serv1"}[1h] 

error_per_min{account="me", host="serv2"}[1h] 

resp_per_min{account="je", others="serv3"}[1h]

How can I combine these queries into one and get the result all at once? Is there a way to combine queries along with the label filters into one and fetch range vector for each of the queries at the same time

Can someone suggest if this is possible or not.

you have three options:

1) Issue the requests in parallel.  Provided the dataset size isn't too huge, and your prometheus instance has enough cpu/memory to handle the load, this could work

2) Use regexes on the vector names

{__name__=~"(calls|error|resp)_per_min, account=~"se|me|je", ...}

3) Some combination of the first 2
