下载地址 https://github.com/prometheus/pushgateway/releases/download/v1.5.1/pushgateway-1.5.1.windows-amd64.zip
2、修改prometheus的配置
修改prometheus.yml添加pushgateway的job
# my global config
global:scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.# scrape_timeout is set to the global default (10s).# Alertmanager configuration
alerting:alertmanagers:- static_configs:- targets:# - alertmanager:9093# Load rules once and periodically evaluate them according to the global evaluation_interval.
rule_files:# - first_rules.yml# - second_rules.yml# A scrape configuration containing exactly one endpoint to scrape:
# Here its Prometheus itself.
scrape_configs:# The job name is added as a label jobjob_name to any timeseries scraped from this config.- job_name: prometheus# metrics_path defaults to /metrics# scheme defaults to http.static_configs:- targets: [localhost:9090]# - job_name: station
# metrics_path: /prometheus
# static_configs:
# - targets: [localhost:14501]- job_name: pushgatewayhonor_labels: truestatic_configs:- targets: [localhost:9091]labels:instance: pushgateway3、启动pushgateway
解压pushgateway 点击pushgateway.exe运行
4、测试推送数据到pushgateway(java)
引入依赖

stationSystemCpuTotal.labels(A, B).set(10);
MapString, String groupingKey new HashMap() {{put(collector_name, cpu);}};
pushGateway.pushAdd(stationSystemCpuTotal , test-job, groupingKey);5、查看pushgatway 6、查看Prometheus
