How to send metrics using Python

Interesting Python Graphite Libraries

  • A Python module for sending metrics to Graphite over UDP https://github.com/derpston/python-graphiteudp - Charlie wrote this library, and we use it internally. It’s a good simple library for sending metrics over UDP in Python.

  • Diamond - Send system metrics to Graphite Diamond - A really useful Python daemon to send system metrics such as CPU usage, load, Disk IO, etc.

Sending a metric via TCP

import socket

conn = socket.create_connection(("YOUR-UID.carbon.hostedgraphite.com", 2003))
conn.send("YOUR-API-KEY.foo.py-tcp 1.2\n")
conn.close()

Sending a metric via UDP

import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.sendto("YOUR-API-KEY.foo.py-udp 1.2\n", ("YOUR-UID.carbon.hostedgraphite.com", 2003))

Sending a metric using HTTP POST

import urllib2, base64

url = "https://www.hostedgraphite.com/api/v1/sink"
api_key = "YOUR-API-KEY"

request = urllib2.Request(url, "foo.py-http 1.2")
request.add_header("Authorization", "Basic %s" % base64.encodestring(api_key).strip())
result = urllib2.urlopen(request)

Sending a metric via TCP over TLS tunnel

import socket, ssl

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
ssl_sock = ssl.wrap_socket(s)
ssl_sock.connect(("YOUR-UID.carbon.hostedgraphite.com", 20030))
ssl_sock.write("YOUR-API-KEY.foo.py-tls 1.2\n")

Python 3.x

Sending a metric via TCP

import socket
conn = socket.create_connection(("YOUR-UID.carbon.hostedgraphite.com", 2003))
conn.send("YOUR-API-KEY.foo.py3-tcp 1\n".encode('utf-8'))
conn.close()

Sending a metric via UDP

import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.sendto("YOUR-API-KEY.foo.py3-udp 1\n".encode('utf-8'), ("YOUR-UID.carbon.hostedgraphite.com", 2003))

Sending a metric using HTTP POST

With the requests module:

import requests
response = requests.put("http://www.hostedgraphite.com/api/v1/sink", auth = ("YOUR-API-KEY", ""),
data = "foo.py3-http 1")

Using only stdlib modules: (Contributed by Waldo, thanks!)

import urllib.request
from base64 import b64encode

url = "https://www.hostedgraphite.com/api/v1/sink"
api_key = b'YOUR-API-KEY'
metric = "foo 1.2".encode('utf-8')
headers = {'Authorization': b'Basic ' + b64encode(api_key)}
request = urllib.request.Request(url, metric, headers)
result = urllib.request.urlopen(request)

Sending a metric via TCP over TLS tunnel

import socket, ssl

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
ssl_sock = ssl.wrap_socket(s)
ssl_sock.connect(("YOUR-UID.carbon.hostedgraphite.com", 20030))
ssl_sock.write("YOUR-API-KEY.foo.py3-tls 1.2\n".encode("UTF-8"))

Sending a metric via StatsD

import socket, ssl

import socket

statsd_host = 'statsd.hostedgraphite.com'
statsd_port = 8125
metric_key = 'YOUR-API-KEY.foo.py3-statsd'
metric_value = 1.2

metric_message = f"{metric_key}:{metric_value}|c"

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.sendto(metric_message.encode('utf-8'), (statsd_host, statsd_port))
sock.close()

When sending StatsD metrics, make sure to specify counters (c), gauges (g), or timers (ms).
