Prometheus监控Redis集群
pre
Prometheus 监控 Redis cluster，其实套路都是一样的，使用 exporter。 exporter 负责采集指标，通过 http 暴露给 Prometheus 拉取。granafa 则通过这些指标绘图展示数据。Prometheus 收集的数据还会根据你设置的告警规则判断是否要发送给 Alertmanager， Alertmanager 则要判断是否要发出告警。
Alertmanager 告警分为三个阶段
Inactive 触发告警的规则会被发送到这来。 Pending 你设置的等待时间，即规则里面的 for Firing 发送告警到邮件、钉钉之类的

err
现在 外网能telnet 通 hello的 redis 端口 不过 prometheus 那里还是 0 记得要用 dos2unix 去格式化一下 不然配置很容易出错的 yml 0 err="error loading config from \"/etc/prometheus/prometheus.yml\": couldn't load configuration (--config.file=\"/etc/prometheus/prometheus.yml\"): parsing YAML file /etc/prometheus/prometheus.yml: yaml: line 47: did not find expected key"
* grafana 模板
~/prometheus/redis_mon.yml
有个 763 也是不错呢
- 如果client export 那边服务没起来 是跑不动 9090的 例如 昨天加的mysql 没跑 今天加redis 完全打不开
- redis 单机 版本
图形garafa 还不行 有空再看吧 https://yq.aliyun.com/articles/251478
