I ran it as follows.
Instead of 0, 59 came back.
Apparently, ServiceDiscovery is "0/59".
I would like to know the value of Active Targets.
What should I do?
# Query
prometheus_sd_discovered_targets{config="kube-system/fluentd-logging/0"}
# Result
prometheus_sd_discovered_targets{app="prometheus-k8s",config="kube-system/fluentd-logging/0",endpoint="web",instance="10.233.104.255:9090",job="prometheus-k8s",name="scrape",namespace="monitoring",pod="prometheus-k8s-1",service="prometheus-k8s"}
59
