Grafana Prometheus
1

I am tried to config promtail 3.3.0 to send kubernetes pod log to loki in kubernetes like this:

server:
  disable: true

positions:
  filename: /tmp/positions.yaml

clients:
  - url: http://129.114.36.24:3100/loki/api/v1/push

scrape_configs:
- job_name: 'kubernetes-pods'
  kubernetes_sd_configs:
    - role: pod

and this is the deamonset config:

the promtail did not send any logs to loki, am I missing something?

Promtail is feature complete. All future feature development will occur in Grafana Alloy.
