A situation arose where I was unable to use nc to send some metrics to a local Graphite server. Thanksfully, Python was installed (albeit, quite a dated version) that allowed me to set up a socket to send the data over the wire.
import commands import socket import time def get_device_stats(device): # Retrieve 1 second average from `iostat` for device. status, output = commands.getstatusoutput('iostat 1 2 -kd -p /dev/%s | awk NR==7' % device) values = output.split() timestamp = int(time.time()) send_metric(device, 'iops', values, timestamp) send_metric(device, 'read', values, timestamp) send_metric(device, 'write', values, timestamp) def send_metric(device, metric, value, timestamp): s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.connect(('220.127.116.11', 2003)) # New-line character is important here, otherwise Graphite will not parse the sent data. s.sendall('disks.%s.%s.total %s %s\n' % (device, metric, value, timestamp)) s.close() devices = ['sda', 'sdb', 'sdc'] for device in devices: get_device_stats(device)
