性能监控之Telegraf+InfluxDB+Grafana

发表于

「这是我参与11月更文挑战的第23天，活动详情查看：2021最后一次更文挑战」

一、前言

本文主要介绍 Telegraf 在 window 上安装及监控入门

二、安装&部署

1.找到下载地址：portal.influxdata.com/downloads/

在这里插入图片描述

2.创建目录 C:\Program Files\Telegraf（如果安装在其他位置，请指定 -config 具有所需位置的参数）
3.解压软件包，将文件 telegraf.exe 和 telegraf.conf 文件放入 C:\Program Files\Telegraf

在这里插入图片描述

4.要将服务安装 到Windows 服务管理器中，以管理员身份在 CMD 中运行以下命令。如有必要，可以用双引号将文件
目录中的任何空格换行 "<file directory>"：

1
bash复制代码C:\"Program Files"\Telegraf\telegraf.exe --service install

或者

1
bash复制代码C:\Program Files\Telegraf>telegraf.exe --service install

在这里插入图片描述

5.编辑 telegraf.conf 配置文件以满足要求。

6.要验证它是否有效，请运行：

1
bash复制代码C:\"Program Files"\Telegraf\telegraf.exe --config C:\"Program Files"\Telegraf\telegraf.conf --test

或者

1
bash复制代码C:\Program Files\Telegraf>telegraf.exe --config telegraf.conf --test

要开始收集数据，请运行：

1
bash复制代码net start telegraf

7.其他操作
telegraf 可以通过 --service 管理自己的服务：

bash复制代码telegraf.exe --service install		#安装服务
telegraf.exe --service uninstall	#删除服务
telegraf.exe --service start		#启动服务
telegraf.exe --service stop			#停止服务

# Configuration for sending metrics to InfluxDB

  # urls = ["udp://127.0.0.1:8089"]
  urls = ["http://172.16.14.111:8086"]

  ## The target database for metrics; will be created as needed.
  database = "bigscreen"

  ## If true, no CREATE DATABASE queries will be sent.  Set to true when using
  ## Telegraf with a user without permissions to create databases or when the
  ## database already exists.
  # skip_database_creation = false

  ## Name of existing retention policy to write to.  Empty string writes to
  ## the default retention policy.  Only takes effect when using HTTP.
  # retention_policy = ""

  ## Write consistency (clusters only), can be: "any", "one", "quorum", "all".
  ## Only takes effect when using HTTP.
  # write_consistency = "any"

  ## Timeout for HTTP messages.
  timeout = "5s"

  ## HTTP Basic Auth
   username = "telegraf"
   password = "telegraf"

  ## HTTP User-Agent
  # user_agent = "telegraf"

  ## UDP payload size is the maximum packet size to send.
  # udp_payload = "512B"

  ## Optional TLS Config for use on HTTP connections.
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

  ## HTTP Proxy override, if unset values the standard proxy environment
  ## variables are consulted to determine which proxy, if any, should be used.
  # http_proxy = "http://corporate.proxy:3128"

  ## Additional HTTP headers
  # http_headers = {"X-Special-Header" = "Special-Value"}

  ## HTTP Content-Encoding for write request body, can be set to "gzip" to
  ## compress body or "identity" to apply no encoding.
  # content_encoding = "identity"

  ## When true, Telegraf will output unsigned integers as unsigned values,
  ## i.e.: "42u".  You will need a version of InfluxDB supporting unsigned
  ## integer values.  Enabling this option will result in field type errors if
  ## existing data has been written.
  # influx_uint_support = false

四、集成Grafana Dashboard

访问 grafana.com/dashboards?… 下载一个合适的 Dashboard 模版

在这里插入图片描述
Grafana 导入 Dashboard 模版

具体请参考 性能监控之Telegraf+InfluxDB+Grafana服务器实时监控

五、监控效果

Grafana Dashboard 最终效果如下：
