edit Prometheus Medium prometheus.yaml file

- job_name: 'pushgateway'
 scrape_interval: 10s
 honor_labels: true # Add this configuration exporter Nodes upload data ⼀ Some labels will not be pushgateway The same label of the node overrides 
 static_configs:

 labels:
 instance: pushgateway

because prometheus To configure pushgateway When , Will also specify job and instance, But it only means
pushgateway example , Can't really express the meaning of collecting data . So configuration pushgateway Need to add
honor_labels:true, Avoid collecting the data itself job and instance Be overwritten
