Efficiently querying multiple metrics via http api?

[Tekraj Chhetri]

Hi,

I have a list of metrics that I need to query via prometheus HTTP API. I need to query within range say 2019-8-8 till now. What would be the efficient way to query? I would like to query all at once within the given date range.

node_cpu_core_total

node_disk_read_bytes_total

node_disk_written_bytes_total

smartmon_command_timeout_value

currently I am querying like http://127.0.0.1:9090/api/v1/query_range?query={__name__='node_memory_MemAvailable_bytes|node_memory_MemTotal_bytes'}&start=2020-03-05T20:08:51.781Z&end=2020-03-05T20:11:00.781Z&step=15s

Thank you.
