Redis shake实现可视化监控的示例代码

作者:真雪

Redis可视化监控是通过监控Redis服务器的各项指标和状态,并将其以可视化的方式展示给用户,本文给大家介绍了Redis shake实现可视化监控,并通过代码示例讲解的非常详细,需要的朋友可以参考下

一.redis-shake v4

1.镜像

2.shake.toml

status_port = 8888 获取监控数据端口,部署启动时映射8888端口

可部署多个 redis-shake 10.111.11.12:8888  10.111.11.12:8889 10.111.11.12:8890

二.json-exporter配置

1.Dockerfile

FROM prometheuscommunity/json-exporter:latest
 
USER root
RUN mkdir -p  /opt
WORKDIR /opt
COPY  config.yml /opt/

2.config.yml

根据上边返回的json数据,制定自己需要的监控模版,部署json-exporter 10.111.11.11:7979

modules:
  default:
    headers:
      X-Dummy: my-test-header
    metrics:
    - name: shake_consistent
      help: Example of sub-level value scrapes from a json
      path: '{.consistent}'
      labels:
        start_time: '{.start_time}'
    - name: shake_total_entries_count
      type: object
      help: Example of sub-level value scrapes from a json
      path: '{.total_entries_count}'
      values:
        read_count: '{.read_count}'     # static value
        read_ops: '{.read_ops}' # dynamic value
        write_count: '{.write_count}'
        write_ops: '{.write_ops}'
    - name: shake_per_cmd_entries_count_restore
      type: object
      help: Example of sub-level value scrapes from a json
      path: "{.per_cmd_entries_count.RESTORE}"
      values:
        read_count: '{.read_count}'
        read_ops: '{.read_ops}'
        write_count: '{.write_count}'
        write_ops: '{.write_ops}'
    - name: shake_per_cmd_entries_script_load
      type: object
      help: Example of sub-level value scrapes from a json
      path: "{.per_cmd_entries_count.SCRIPT-LOAD}"
      values:
        read_count: '{.read_count}'
        read_ops: '{.read_ops}'
        write_count: '{.write_count}'
        write_ops: '{.write_ops}'
    - name: shake_reader
      type: object
      help: Example of sub-level value scrapes from a json
      path: "{.reader}"
      labels:
        address: '{.address}'          # dynamic label
        dir: '{.dir}'
        status: '{.status}'
      values:
        rdb_file_size_bytes: '{.rdb_file_size_bytes}'
        rdb_received_bytes: '{.rdb_received_bytes}'
        rdb_sent_bytes: '{.rdb_sent_bytes}'
        aof_received_offset: '{.aof_received_offset}'
        aof_sent_offset: '{.aof_sent_offset}'
        aof_received_bytes: '{.aof_received_bytes}'
    - name: shake_writer
      type: object
      help: Example of sub-level value scrapes from a json
      path: "{.writer}"
      labels:
        name: '{.name}'          # dynamic label
      values:
        unanswered_bytes: '{.unanswered_bytes}'
        unanswered_entries: '{.unanswered_entries}'

三.prometheus配置

1.prometheus.yml

global:
  scrape_interval: 15s 
  evaluation_interval: 15s
 
scrape_configs:
  - job_name: json_exporter
    metrics_path: /probe
    file_sd_configs:
    - files:
      - 'redis-shake.json'
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        replacement: 10.111.11.11:7979 # json-exporter地址

2.redis-shake.json

单独的文件配置可实现动态加载,同时可添加自定义的标签在文件中

[
# labels为自定义的标签,targets为部署各个redis-shake地址
{"labels": {"env-1":"团队1"},"targets": ["http://10.111.11.12:8888"]},
{"labels": {"env-1":"团队2"},"targets": ["http://10.111.11.12:8889"]},
{"labels": {"env-1":"团队3"},"targets": ["http://10.111.11.12:8890"]}
]

四.grafana

上边的都配置好,把自己的peometheus数据源添加到grafana中,就可以设置自己想要的监控界面了
