Prometheus curl API query issue

Question

I am trying to construct curl API query to get Json data from Prometheus. The working in Prometheus UI query looks like:

max_over_time(container_memory_usage_bytes{image!="",pod_name=~"somepod-.*"}[7d])

So I am trying with:

curl 'http://127.0.0.1:20001/api/v1/query?query=max_over_time(container_memory_usage_bytes{(pod_name="somepod-.*")})[1d]' | jq

But depending on brackets it always complaining about something like expected or unexpected character.

Answer 1

You want:

curl -g 'http://127.0.0.1:20001/api/v1/query?query=max_over_time(container_memory_usage_bytes{pod_name=~"somepod-.*"}[1d])' | jq

This disables curl's globbing, which gets in the way here.
