# This creates a http server for getting stats.
# You could easily write a simple loop to pump telemetry data somewhere via http post
# You could setup cache to limit queries to proxy data.

Let's look at some data from the above

data = r.json()
data['10.x.x.x']['backends'][2]['listeners'][1]['name'] # o: haptest2
data['10.x.x.x']['backends'][2]['listeners'][1]['status'] # o: UP
More fun
for x in data['127.0.0.1']['backends']:
for y in x['listeners']:
print(y['name'], y['status'])

for b in haproxy.backends:
print('%s: %s' % (b.name, b.status))
