[[Monitoring with prometheus]]<br />
<br />
<br />
<br />
Prometheus 监控 Redis cluster，其实套路都是一样的，使用 exporter。<br />
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。<br />
<br />
Alertmanager 告警分为三个阶段<br />
<br />
Inactive 触发告警的规则会被发送到这来。<br />
Pending 你设置的等待时间，即规则里面的 for<br />
Firing 发送告警到邮件、钉钉之类的<br />

现在 外网能telnet 通 hello的 redis 端口 不过 prometheus 那里还是 0<br />
<br />
<br />
记得要用 dos2unix 去格式化一下 不然配置很容易出错的 yml<br />
<br />
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"<br />

<br />
有个 763 也是不错呢 <br />
<br />
* 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<br />
<br />
<br />
* redis 单机 版本<br />

图形garafa 还不行 有空再看吧 <br />
