Prometheus监控之thanos+minio+prometheus(Prometheus)

1 Prometheus部署

1.1 Prometheus服务要求

• 建议Prometheus版本为2.2.1或更高版本（包括最新版本）。这是由于Prometheus在以前的版本中不稳定，以及缺少标志端点。
• 每个Prometheus实例都必须有一组全局唯一的标识标签。这些标签将被sidecar和Thanos在许多地方使用。
• 启用--web.enable-admin-api参数，以支持sidecar从Prometheus获取元数据，就像外部标签一样。
• 必须将--storage.tsdb.min-block-duration和--storage.tsdb.max-block-duration设置为相等的值，以禁用本地压缩，以便使用Thanos sidecar上传。建议默认为2小时。

1.2 128Prometheus搭建

1、配置文件
vim prometheus.yml
global:
  scrape_interval: 15s
  evaluation_interval: 15s
  external_labels:
    region: jinan
    replica: A
scrape_configs:
  - job_name: "prometheus"
    static_configs:
    - targets: ["192.168.137.128:9090"]
  - job_name: "node_exporter"
    metrics_path: "/metrics"
    static_configs:
    - targets: ["192.168.137.128:9100"]

2、启动脚本
vim /usr/lib/systemd/system/prometheus.service
[Unit]
Description=Prometheus server
Documentation=https://prometheus.io/
[Service]
User=root
Restart=always
ExecStart=/app/module/prometheus/prometheus \
  --config.file=/app/module/prometheus/prometheus.yml \
  --storage.tsdb.path=/app/module/prometheus/data \
  --storage.tsdb.retention.time=2h \
  --storage.tsdb.min-block-duration=2h \
  --storage.tsdb.max-block-duration=2h \
  --web.listen-address=0.0.0.0:9090 \
  --web.enable-admin-api \
  --web.enable-lifecycle
ExecReload=/bin/kill -HUP $MAINPID
Restart=on-failure
RestartSec=20
TimeoutStopSec=20
SendSIGKILL=no
LimitNOFILE=8192
[Install]
WantedBy=multi-user.target

3、启动服务
systemctl daemon-reload
systemctl start prometheus.service
systemctl status -l prometheus.service
