Telegraf_

MyPerf4J 2.0 及其之前本身不访问 InfluxDB，而是通过把统计数据写入日志文件中，通过 Telegraf 把统计数据导入 InfluxDB 中。

步骤如下:

• 安装 Telegraf

• 配置 /usr/local/etc/telegraf.conf

  # Global tags can be specified here in key="value" format.
  [global_tags]
    dc = ""
  
  # Configuration for telegraf agent
  [agent]
    ## Default data collection interval for all inputs
    interval = "1s"
    ## Rounds collection interval to 'interval'
    ## ie, if interval="10s" then always collect on :00, :10, :20, etc.
    round_interval = true
    metric_batch_size = 1000
    metric_buffer_limit = 10000
    collection_jitter = "0s"
    ## Default flushing interval for all outputs. You shouldn't set this below
    ## interval. Maximum flush_interval will be flush_interval + flush_jitter
    flush_interval = "1s"
    flush_jitter = "0s"
    precision = "ms"
    debug = false
    quiet = false
    logfile = "/tmp/telegraf.log"
    ## Override default hostname, if empty use os.Hostname()
    hostname = ""
    ## If set to true, do no set the "host" tag in the telegraf agent.
    omit_hostname = false
  
  [[outputs.influxdb]]
    urls = ["http://127.0.0.1:8086"]
    database = "MyPerf4J_Test"
    retention_policy = ""
    write_consistency = "any"
    timeout = "5s"
  
  [[inputs.tail]]
    files = ["/data/logs/MyPerf4J/metrics.log"]
    from_beginning = false
    pipe = false
    ## Method used to watch for file updates.  Can be either "inotify" or "poll".
    watch_method = "inotify"
    data_format = "influx"
