Prometheus配置

• prometheus.yml配置

1. 非集群

- job_name: 'redis_exporter'
    static_configs:
    - targets:
	  # redis_exporter访问地址
      - 172.16.30.184:9121

2. 集群

- job_name: 'redis_exporter_targets'
    static_configs:
      # redis集群访问地址
      - targets:
        - redis://172.16.238.43:6379
        - redis://172.16.141.201:6379
        - redis://172.16.238.42:6379
    params:
      check-keys: ["metrics:*"]
    metrics_path: /scrape
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 172.16.88.155:9121
  - job_name: 'redis_exporter'
    static_configs:
    - targets:
      # redis_exporter访问地址
      - 172.16.88.155:9121
