process_blackbox_exporter部署

process-exporter docker docker部署

• docker拉取镜像无法拉取问题

docker run -d --name process-exporter -p 9256:9256 --restart unless-stopped  -v  /home/prometheus/process_exporter.yml:/process_exporter.yml timn/process-exporte  --config.path=process_exporter.yml

process-exporter二进制安装

• 下载

wget https://github.com/ncabatoff/process-exporter/releases/download/v0.7.10/process-exporter-0.7.10.linux-amd64.tar.gz

• 定义配置文件

cd /home/prometheus/
vim process_exporter.yml
process_names:
#指定多个进程：
- name: "{{.Matches}}"
  cmdline:
  - 'docker'
- name: "{{.Matches}}"
  cmdline:
  - 'fdfs_storaged'
- name: "{{.Matches}}"
  cmdline:
  - 'fdfs_trackerd'
- name: "{{.Matches}}"
  cmdline:
  - 'sshd'
  
#指定所有进程方式：
#process_names:
# - name: "{{.Comm}}"
#   cmdline:
#    - '.+'

• 添加服务启动

cat > /usr/lib/systemd/system/process_exporter.service << EOF

systemctl daemon-reload && systemctl enable process_exporter
systemctl daemon-reload && systemctl enable process_exporter

• Prometheus配置文件添加对应节点

scrape_configs:
  - job_name: process-exporter
    static_configs:
      - targets: ['192.168.27.47:9256']
        labels:
          instance: process-exporter

blackbox-exporter 部署

• docker 部署blackbox-exporter

docker run -itd -p 9115:9115 --name blackbox_exporter prom/blackbox-exporter:v0.25.0 

• grafana 上导入 blackbox_exporter dashboard: 13659
• blackbox_exporter 采集加入的采集池中
