Grafana + Prometheus 如何在查询指标中使用正则表达式？

Question

We are dynamically adding new metrics. Is it possible to use regex in Grafana query metrics?

application_test_total{color="0"}

application_test_total{color="1"}

application_test_total{color="2"}

How to avoid this?

sum(application_test_total{color="0"})+sum(application_test_total{color="1"})

Is it possible to replace with this?

application_test_total{color="[0-9]{2}"}

Answer 1

You can replace:

sum(application_test_total{color="0"})+sum(application_test_total{color="1"})

To:

sum(application_test_total{color=~"[0-9]{1}"})
