yaml - Loki 没有提醒 Alertmanager

Question

我是 Loki 的新手，在 Loki 中发出了警报，但我在 Alertmanager 中没有看到任何通知。 Loki 工作正常(收集日志)，Alertmanager 也正常(从其他来源获取警报)，但来自 loki 的日志不会推送到 alertmanager。

洛基配置:

auth_enabled: false

server:
  http_listen_port: 3100

ingester:
  lifecycler:
    address: 127.0.0.1
    ring:
      kvstore:
        store: inmemory
      replication_factor: 1
    final_sleep: 0s
  chunk_idle_period: 1h       # Any chunk not receiving new logs in this time will be flushed
  max_chunk_age: 1h           # All chunks will be flushed when they hit this age, default is 1h
  chunk_target_size: 1048576  # Loki will attempt to build chunks up to 1.5MB, flushing first if chunk_idle_period or max_chunk_age is reached first
  chunk_retain_period: 30s    # Must be greater than index read cache TTL if using an index cache (Default index read cache TTL is 5m)
  max_transfer_retries: 0     # Chunk transfers disabled

  ring:
    kvstore:
      store: inmemory
  enable_api: true

Docker-compose Loki:

 loki:
    image: grafana/loki:2.0.0
    container_name: loki
    ports:
      - "3100:3100"
    volumes:
      - ./loki/etc/local-config.yaml:/etc/loki/local-config.yaml
      - ./loki/etc/rules/rules.yaml:/etc/loki/rules/rules.yaml
    command:
      -  '--config.file=/etc/loki/local-config.yaml'

洛基规则:

groups:
  - name: rate-alerting
    rules:
    - alert: HighLogRate
      expr: |
           count_over_time(({job="grafana"})[1m]) >=0
      for: 1m

有人知道问题出在哪里吗？

我终于让它工作了。

下面是我的统治者配置

ruler:
  storage:
    type: local
    local:
      directory: /etc/loki/rulestorage
  rule_path: /etc/loki/rules
  alertmanager_url: http://alertmanager:9093
  ring:
    kvstore:
      store: inmemory
  enable_api: true
  enable_alertmanager_v2: true

在目录下创建

• /etc/loki/rulestorage/fake
• /etc/loki/rules/fake
• 将 alert_rules.yaml 复制到/etc/loki/rulestorage/fake 下
• 在/etc/loki/rulestorage/fake 下为 loki 用户授予完全权限

繁荣
