[vthriller]

Issue type: Bug report

What happened:

panic: inconsistent label cardinality: expected 3 label values but got 2 in []string{"rpc", "POST"}

goroutine 65 [running]:
github.com/prometheus/client_golang/prometheus.(*CounterVec).WithLabelValues(0xc000182078, 0xc000390030, 0x2, 0x3, 0xb63401, 0xc000354060)

How to reproduce it (as minimally and precisely as possible):

    relabel_configs:
    - target_label: status
      #from: status # panics both with and without this option
      only_counter: true

Environment:

• Exporter version: 1.9.0
• OS (e.g. from /etc/os-release): any

Apologies, this should not have gotten stale. I haven't gotten around to investigate this yet, though. In the meantime, all contributions are welcome -- even a PR with a failing behave test case would already be helpful. 🙂
