Scheduled Job Queue and Sidekiq job durations and executions.

Discourse Prometheus is smart enough to aggregate data for all forked unicorn processes and present it as cohesive metrics on a single endpoint. We use it internally to keep track of our sites.
Sample dashboard at:
Discourse global setting called prometheus_trusted_ip_allowlist_regex (env: DISCOURSE_PROMETHEUS_TRUSTED_IP_ALLOWLIST_REGEX) is allowing to set Prometheus’s trusted IP addresses. The setting accepts regular expression to set advanced IP ranges. This is useful in a case when Prometheus IP address is dynamic.
I’m currently managing discourse on Kubernetes, running on multiple app and sidekiq pods. I have a couple of questions regarding the plugin:
Does the plugin aggregate metrics from all the app pods? I’m assuming it does aggregate metrics for unicorn processes running on a single instance/pod.
정확히 무슨 일이 일어나고 있는지 확실하지는 않지만, 이 통합(integration)이 더 이상 작동하지 않습니다. Grafana 대시보드에 아무것도 표시되지 않네요… /metrics 엔드포인트는 응답을 반환하지만, 그 이상의 동작은 제대로 이루어지지 않습니다.
아래와 같은 많은 오류가 발생하고 있습니다
