prometheus pushgateway-简单-脚本-自定义 - EOF 运维神器 federate + 多instances聚合

0.pushgateway的安装和配置

tar -zxf pushgateway-1.2.0.linux-amd64.tar.gz

./pushgateway  &

在Prometheus添加配置

- job_name: 'node_111'
  static_configs:
    - targets: ['10.0.0.111:9100']labels:instance: 111_9100- targets: ['10.0.0.134:9100']labels:instance: 134_9100
- job_name: 'pushgateway_test'  #这个名称可以自定义，后面会用到
  static_configs:
    - targets: ['10.0.0.111:9091']  #这里是pushgateway的地址

 

1.pushgateway发送数据的API格式

http://pustgatewayIP/metrices/job/job名/标签名/标签值
echo "metricname 120" | curl --data-binary @- http://10.0.0.111:9091/metrics/job/myjobname/labels/mylabelname

 2.数据类型

1、counter类型
#counter是可增长的，重启时候会被置成0，用于任务个数，只增不减
cat <<EOF | curl --data-binary @- http://pushgatewayIP:9091/metrics/job/docker_runtime/instance/xa-lsr-billubuntu
    # TYPE docker_runtime counter
    docker_runtime{name="cadvisor"} 33
    docker_runtime{name="nginx"} 331
    docker_runtime{name="abc"} 332
EOF

2.发送gauage类型
"Random value of the request"
cat <<EOF | curl --data-binary @- http://pushgatewayIP:9091/metrics/job/docker_runtime/instance/xa-lsr-billubuntu
    # TYPE docker_runtime gauge
    # HELP docker_runtime time sec
    docker_runtime{name="nginx"} 22
   docker_runtime{name="cadvisor"} 22
   docker_runtime{name="bbc"} 22
EOF

3.promql简单例子

cat <<EOF | curl --data-binary @- http://pushgatewayIP:9091/metrics/job/docker_runtime/instance/xa-lsr-billubuntu
    # TYPE docker_runtime counter
      docker_runtime{name="abc"} 332
EOF

rate(docker_runtime{name='abc'}[1m])

 4. Prometheus的数据符合格式

<metric name>{<label name>=<label value>, ...}
api_http_requests_total{method="POST", handler="/messages"}
