Pushgateway
部署 Pushgateway
cd /tmp
wget https://github.com/prometheus/pushgateway/releases/download/v1.9.0/pushgateway-1.9.0.linux-amd64.tar.gz
tar xf pushgateway-1.9.0.linux-amd64.tar.gz -C /usr/local
cd /usr/local
ln -s pushgateway-1.9.0.linux-amd64 pushgateway
# 启动 pushgateway
nohup /usr/local/pushgateway/pushgateway &>> pushgateway.log &修改 Prometheus 配置文件
# vim prometheus.yml
# 路径:/usr/local/prometheus/prometheus.yml
# 在 scrape_configs 下新增 job_name
scrape_configs:
- job_name: 'pushgateway'
static_configs:
- targets: ['192.168.31.23:9091']重新加载配置
# 让 Prometheus 重新读取配置
kill -HUP `pidof prometheus`访问 metrics
curl -s 192.168.31.23:9091/metrics测试脚本推送
可将脚本设置为定时任务(分钟级)或者死循环(秒级),即可实现定时推送监控指标
cat get_cpu_metrics.sh
#!/bin/bash
# 1.vars
job="pushgateway"
instance="192.168.31.23:9091"
pushgw="http://192.168.31.23:9091"
cores=$(lscpu | awk '/^CPU\(s\)/{print $2}')
# 2.commands
# 以下命令可实现推送自定义的监控指标(此处为获取 cpu 核心数)至 pushgateway
# cpu_cores 为自定义的监控指标
# @- 表示数据来自管道符
echo "cpu_cores $cores" | \
curl --data-binary @- ${pushgw}/metrics/job/${job}/instance/${instance}查看
