Malformed http_route values

[krisztianfekete]

Hello,

Here's my Beyla configmap for 1.4.1:

apiVersion: v1
kind: ConfigMap
metadata:
  name: beyla-config
  namespace: beyla
data:
  beyla-config.yml: |
    routes:
      unmatched: path
      ignored_patterns:
        - /stats/*
        - /healthz/*
    attributes:
      kubernetes:
        enable: true
    discovery:
      services:
        - k8s_namespace: "istio-system"

Some of my http_route values seems to be malformed in the metrics exposed directly on my Beyla pod, e.g:

http_client_request_body_size_bytes_bucket{http_request_method="",http_response_status_code="200",http_route="`

The malformed lines should likely be /stats/prometheus, but notice that I have an ignored_patterns rule for that.

Hi @krisztianfekete, can you please share your Beyla version? We had a bug in our Go specific instrumentation, but I believe it should be resolved in our latest release.

Sorry, I missed it, you are running 1.4.1. We'll investigate...
