As the name implies this a script to publish MQTT metrics into statsd. It was
|
|
originally designed to handle metrics from the $SYS/ topics in the mosquitto
|
|
broker, but the framework is generic enough that any MQTT topic can be used.
|
|
|
|
Installation
|
|
------------
|
|
|
|
mqtt_statsd is available via pypi, so all you need to do is run::
|
|
|
|
pip install -U mqtt_statsd
|
|
|
|
to get mqtt_statsd on your system. If you need to use a development version of
|
|
mqtt_statsd you can clone the repo and install it locally with::
|
|
|
|
git clone https://github.com/mtreinish/mqtt_statsd.git && pip install -e mqtt_statsd
|
|
|
|
which will install mqtt_statsd in your python environment in editable mode for
|
|
local development.
|
|
|
|
Configuring mqtt_statsd
|
|
-----------------------
|
|
|
|
Before you run mqtt_statsd you have to create a yaml configuration file to tell
|
|
mqtt_statsd how to connect to both the MQTT broker, and statsd. As well as which
|
|
MQTT topics to subscribe to and how to populate statsd with the data it gets
|
|
from that MQTT topic. For example::
|
|
|
|
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
|
|
|
|
Running mqtt_statsd
|
|
-------------------
|
|
|
|
Aftering installing and configuring mqtt_statsd running it is incredibly
|
|
straightforward. Just call ``mqtt_statsd`` and it takes 1 mandatory argument,
|
|
the path to the yaml config file. For example::
|
|
|
|
mqtt_statsd my_config_file.yaml
|
