Prometheus monitoring method and index interpretation of influxdb

Configuration method

influxdb Bring it with you metrics（http://$ip:8086/metrics）, But the content is limited , Need a telegraf To expand the monitoring content .

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

telegraf Here as an indicator collector , There are two ways to use it ：

1、 Don't use influxdb_exporter, Direct will telegraf As exporter, be telegraf The configuration is ：

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

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

Corresponding prometheus Of target by $ip:9273.

2、 Use influxdb_exporter (https://github.com/prometheus/influxdb_exporter), be telegraf The configuration is ：

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

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

among http://localhost:9122  by influxdb_exporter The monitoring address of , here prometheus Of target It is written as   $ip:9122.

Two ways metrics The same name .
