# scrape_configs is the scrape configuration of prometheus 
# which is fully compatible with prometheus scrap.
scrape_configs:
# job_name will be used as the label in prometheus, 
# and in skywalking meterdata will be used as the service name.
# Set the scrape interval through scrape_interval
# static_configs is the service list of metrics server

# In K8S, service discovery needs to be used to obtain the metrics server list.
# Configure and select related pods through kubernetes_sd_configs.selectors
# Because K8S resource permissions are involved, K8S serviceaccount needs to be configured
# tls_config is the certificate assigned by K8S to satellite, and generally does not need to be changed.
