Hi,
I am running in kubernetes, and some of the pods uses annotation:
annotations:
prometheus.io/path: /
prometheus.io/port: "9250"
prometheus.io/scrape: "true"
however, for some other pods, we are not using annotation, but simply
define:
ports:
- containerPort: 8889
name: metrics
and the config as below, after adding
__meta_kubernetes_pod_container_port_name,
the ones with just annotation stopped working. Prometheus no longer scrape
from those pods, any suggestions?
Thanks!
- job_name: 'kubernetes-pod-annotation'
kubernetes_sd_configs:
- role: pod
relabel_configs:
- source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_scrape]
action: keep
regex: true
- source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_path]
action: replace
target_label: __metrics_path__

- source_labels: [__meta_kubernetes_pod_container_port_name] # try to keep
the port only if the name is metrics
action: keep

- source_labels: [__address__,
