Prometheus监控influxdb的方法及指标释义

配置方法

influxdb本身自带metrics（http://$ip:8086/metrics），但内容有限，需借助telegraf来扩展监控内容。

wget https://dl.influxdata.com/influxdb/releases/influxdb-1.7.8.x86_64.rpm
yum localinstall influxdb-1.7.8.x86_64.rpm

telegraf在这里作为指标收集器，有两种使用方法：

1、不使用influxdb_exporter，直接将telegraf作为exporter，则telegraf的配置为：

# /etc/telegraf/telegraf.conf
[[outputs.prometheus_client]]
  listen = ":9273"

[[inputs.influxdb]]
  urls = [
    "http://localhost:8086/debug/vars"
  ]

对应prometheus的target为 $ip:9273。

2、使用influxdb_exporter (https://github.com/prometheus/influxdb_exporter)，则telegraf的配置为：

# /etc/telegraf/telegraf.conf
[[outputs.influxdb]]
  urls = ["http://localhost:9122"]

[[inputs.influxdb]]
  urls = [
    "http://localhost:8086/debug/vars"
  ]

其中 http://localhost:9122 为influxdb_exporter的监听地址，此时prometheus的target则写为  $ip:9122。

两种方式metrics名称相同。
