忘是亡心i 2021-11-17 02:04 261阅读 0赞

[Telegraf][]是TICK堆栈中的度量收集代理。

在安装之前先安装InfluxDB和Chronograf 。

1.下载Telegraf镜像

docker pull telegraf

2.创建数据目录

/root/runenv/opt/docker/telegraf

/root/runenv/opt/docker/telegraf/run

3.导出默认配置文件

docker run --rm telegraf telegraf config > telegraf.conf

4.修改配置文件

主要修改 urls、database、username、password、timeout等配置项

[[outputs.influxdb]]
      ## The full HTTP or UDP URL for your InfluxDB instance.
      ##
      ## Multiple URLs can be specified for a single cluster, only ONE of the
      ## urls will be written to each interval.
      # urls = ["unix:///var/run/influxdb.sock"]
      # urls = ["udp://127.0.0.1:8089"]
      # urls = ["http://127.0.0.1:8086"]
      urls = ["http://ip:8086"]
    
      ## The target database for metrics; will be created as needed.
      ## For UDP url endpoint database needs to be configured on server side.
      database = "telegraf"
    
      ## The value of this tag will be used to determine the database.  If this
      ## tag is not set the 'database' option is used as the default.
      # database_tag = ""
    
      ## 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 = "1h"
    
      ## 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 = "用户"
      password = "密码"
    
      ## 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

5.配置数据库

在InfluxDB中创建数据库同配置文件中的 database 参数

创建用户同配置文件中的 username 和 password 参数

6.启动服务

docker run -d --name=telegraf -v /root/runenv/opt/docker/telegraf/telegraf.conf:/etc/telegraf/telegraf.conf:ro -v /root/runenv/opt/docker/telegraf/run:/var/run telegraf

7.配置Chronograf
