goncha / sendgraph.py
Created November 15, 2012 07:36 — forked from bkjones/sendgraph.py
Fork from bkjones, nagios command to send graphite graph by email
#!/usr/bin/env python
"""
This takes a recipient email address and a graphite URL and sends a
POST to <graphite host>/dashboard/email with a body that looks like
this:
sender=user%40example.com&recipients=user2%40example.com&subject=foo&message=bar&graph_params=%7B%22target%22%3A%22target%3DdrawAsInfinite(metric.path.in.graphite)%22%2C%22from%22%3A%22-2hours%22%2C%22until%22%3A%22now%22%2C%22width%22%3A600%2C%22height%22%3A250%7D
...which will cause the graphite installation to send an email.
