NSQ Consumer 数据采集

简介

采集 NSQ 的消息数据上报到 DataFlux 中。

前置条件

需要给某个topic写入influx格式的数据.
已安装 DataKit（DataKit 安装文档）

配置

进入 DataKit 安装目录下的 conf.d/nsq 目录，复制 nsq_consumer.conf.sample 并命名为 nsq_consumer.conf。示例如下：

修改配置

# Read metrics from NSQD topic(s)
[[inputs.nsq_consumer]]
  ## Server option still works but is deprecated, we just prepend it to the nsqd array.
  # server = "localhost:4150"

  ## An array representing the NSQD TCP HTTP Endpoints
  nsqd = ["localhost:4150"]

  ## An array representing the NSQLookupd HTTP Endpoints
  nsqlookupd = ["localhost:4161"]
  topic = "telegraf"
  channel = "consumer"
  max_in_flight = 100
   ## Maximum messages to read from the broker that have not been written by an
  ## output.  For best throughput set based on the number of metrics within
  ## each message and the size of the output's metric_batch_size.
  ##
  ## For example, if each message from the queue contains 10 metrics and the
  ## output metric_batch_size is 1000, setting this to 100 will ensure that a
  ## full batch is collected and the write is triggered immediately without
  ## waiting until the next flush_interval.
  # max_undelivered_messages = 1000

  ## Data format to consume.
  ## Each data format has its own unique set of configuration options, read
  ## more about them here:
  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
  data_format = "influx"

配置好后，重启 DataKit 即可生效。

采集指标

根据配置不同采集的指标也不同
