ZeroMQ
|
|
======
|
|
|
|
You can export statistics to a ``ZeroMQ`` server.
|
|
|
|
The connection should be defined in the Glances configuration file as
|
|
following:
|
|
|
|
.. code-block:: ini
|
|
|
|
[zeromq]
|
|
host=127.0.0.1
|
|
port=5678
|
|
prefix=G
|
|
|
|
Glances `envelopes`_ the stats before publishing it. The message is
|
|
composed of three frames:
|
|
|
|
1. the prefix configured in the [zeromq] section (as STRING)
|
|
2. the Glances plugin name (as STRING)
|
|
3. the Glances plugin stats (as JSON)
|
|
|
|
Run Glances with:
|
|
|
|
.. code-block:: console
|
|
|
|
$ glances --export zeromq
|
|
|
|
Following is a simple Python client to subscribe to the Glances stats:
|
|
|
|
.. code-block:: python
|
|
|
|
# -*- coding: utf-8 -*-
|
|
#
|
|
# ZeroMQ subscriber for Glances
|
|
#
|
|

|
import json
|
|
import zmq
|
|
|
|
context = zmq.Context()
|
|
|
|
subscriber = context.socket(zmq.SUB)
|
|
subscriber.setsockopt(zmq.SUBSCRIBE, 'G')
|
|
subscriber.connect("tcp://127.0.0.1:5678")
|
|
|
|
while True:
|
|
_, plugin, data_raw = subscriber.recv_multipart()
|
|
data = json.loads(data_raw)
|
|
print('{} => {}'.format(plugin, data))
|
|
|
|
subscriber.close()
|
|
context.term()
|
