yehudayefet/redis-stats 镜像说明

镜像概述

本镜像旨在帮助用户将Redis实例的统计数据推送至Elasticsearch，以便在Kibana等可视化工具中进行实时图表展示和仪表盘构建，有效监控Redis的运行性能与资源使用情况。

核心功能

• 自动收集Redis关键统计指标（连接数、内存使用、命令处理量等）
• 将统计数据持久化存储至Elasticsearch
• 支持在Kibana中对数据进行多维度分析与可视化

使用场景

• 实时监控Redis服务的运行状态
• 构建Redis性能分析仪表盘
• 跟踪Redis资源使用趋势（如内存、连接数变化）

配置说明

依赖条件

• 已部署的Redis实例
• 已部署的Elasticsearch实例

环境变量

启动容器时需配置以下环境变量：

• REDIS_HOST: Redis实例的主机地址
• REDIS_PORT: Redis实例的端口（默认6379）
• ES_HOST: Elasticsearch实例的主机地址
• ES_PORT: Elasticsearch实例的端口（默认9200）

部署示例

Kubernetes CronJob部署（每1分钟执行一次）

yaml
apiVersion: batch/v1beta1
kind: CronJob
metadata:
  name: redis-stats
spec:
  schedule: "*/1 * * * *"
  jobTemplate:
    spec:
      template:
        spec:
          containers:
          - name: redis-stats
            image: yehudayefet/redis-stats
            env:
             - name: REDIS_HOST
               value: "name-of-redis-service.default.svc.cluster.local"
             - name: REDIS_PORT
               value: "6379"
             - name: ES_HOST
               value: "name-of-elasticsearch-logging-service.kube-system.svc.cluster.local"
             - name: ES_PORT
               value: "9200"
          restartPolicy: OnFailure

Elasticsearch索引映射设置

在运行容器前，需执行以下命令创建Redis统计数据的索引映射：

bash
curl -X DELETE "http://[your_elasticsearch_ip]:9200/redis" && \
