mqtt-statsd 0.0.1

安装

mqtt_statsd可以通过pypi获取，因此您只需运行

pip install -U mqtt_statsd

将mqtt_statsd安装到您的系统。如果您需要使用mqtt_statsd的开发版本，您可以克隆仓库并使用以下命令本地安装

git clone https://github.com/mtreinish/mqtt_statsd.git && pip install -e mqtt_statsd

这将使mqtt_statsd在您的Python环境中以可编辑模式安装，以便进行本地开发。

配置mqtt_statsd

在运行mqtt_statsd之前，您必须创建一个yaml配置文件，以告诉mqtt_statsd如何连接到MQTT代理和statsd。以及要订阅哪些MQTT主题以及如何用从该MQTT主题获取的数据填充statsd。例如

statsd:
  hostname: localhost
  # port is optional, the default is shown
  port: 8125
  # prefix is optional, the default is shown
  prefix: mosquitto.stats
mqtt:
  hostname: localhost
  # port is optional, the default is shown
  port: 1883
  # keepalive is optional, the default is shown
  keepalive: 60
  # username is optional, there is no default
  username: foo
  # password is optional, there is no default. If username isn't set this
  # is ignored
  password: PASS
  # qos is optional, the default is shown
  qos: 0
  # websocket is optional, it defaults to False
  websocket: True
topics:
  # You can specify as many topics as you want, and mqtt_statsd will
  # listen to all of them
  - $SYS/broker/messages/publish/sent:
    statsd_topic: publish_messages_sent
    # statsd_type is optional, the default is shown. Valid options are
    # gague, counter, and timer
    statsd_type: gauge
  - $SYS/broker/clients/connected:
    statsd_topic: connected_clients

运行mqtt_statsd

在安装和配置mqtt_statsd之后，运行它非常简单。只需调用mqtt_statsd并传入一个必选参数，即yaml配置文件的路径。例如

mqtt_statsd my_config_file.yaml
