Elasticache是AWS的一种云服务，是一种让用户能够在云中轻松部署、操作和扩展内存缓存的 Web 服务,可自动检测和更换出现故障的缓存节点,从而降低自我管理型基础设施的日常费用，支持Memcached和Redis两种存储引擎。
目前我们采用InfluxDB+Telegraf+Grafana监控来实现对Redis的监控，最终效果图如下所示
InfluxDB主要用于存储数据，Telegraf负责收集Redis的运行数据，并将数据存储到InfluxDB中，Grafana从InfluxDB中取出redis的运行数据，并结合各种仪表盘展示出来，最终效果如下所示

一. 安装Telegraf
1.安装
$ mkdir /usr/local/telegraf $ cd /usr/local/telegraf $ wget https://dl.influxdata.com/telegraf/releases/telegraf-1.14.2_linux_amd64.tar.gz $ tar -zxf telegraf-1.14.2_linux_amd64.tar.gz $ mv telegraf/* . $ ls -lh total 12K drwxr-xr-x 4 tnuser appuser 4.0K Apr 14 14:18 etc drwxr-xr-x 4 tnuser appuser 4.0K Apr 14 14:18 usr drwxr-xr-x 3 tnuser appuser 4.0K Apr 14 14:18 var
2.配置
$ cat etc/telegraf/telegraf.conf [[outputs.influxdb]] urls = ["http://127.0.0.1:8086"] database = "elasticache_us_east_1" skip_database_creation = false [[inputs.redis]] servers = ["tcp://ec1-userredis.mypna.com:6379","tcp://ec1-userredis-b.mypna.com:6379","tcp://ec1-userfavoriteredis.mypna.com:6379"]
3.启动
$ cd usr/bin/
$ ./telegraf --config /usr/local/telegraf/etc/telegraf/telegraf.conf --input-filter redis
二.安装Grafana
参考另一篇博客
https://www.cnblogs.com/ilifeilong/p/10543876.html
三. 安装InfluxDB
参考另一篇博客
https://www.cnblogs.com/ilifeilong/p/12731327.html
四. 配置Grafana
1. 配置数据源
2.新建dashborad并配置panel，下面列出每种panel对应的json元数据
