Ceph Health in Python in a loop

ceph-health.py

#!/usr/bin/env python

import time
import rados
import json

def get_cluster_health(r):
    cmd = {"prefix":"status", "format":"json"}
    ret, buf, errs = r.mon_command(json.dumps(cmd), b'', timeout=5)
    result = json.loads(buf)
    return result['health']['overall_status']

try:
    r = rados.Rados(conffile="/etc/ceph/ceph.conf")
    r.connect()

    for i in range(1000):
        print("{0}: {1}".format(time.time(), get_cluster_health(r)))
        time.sleep(1)
except KeyboardInterrupt:
    pass
finally:
    if r is not None:
        r.shutdown()

The script no longer works since Luminous. The overall_status key is deprecated. Since this gist ranks pretty high on Google, can you update this to simply use the status key?

This way may be very slow when one or two monitor down.
