From time to time somehow ceilometer-collector starts connecting as 'GUEST' user instead of 'NOVA' as defined in ceilometer conf file.
Looking throught tcpdump it is seen that the password is taken correctly, but user is "malformed" to 'guest' instead of 'nova'.
Steps to reproduce:
leave it working for two three days without restarting
Expectected results:
INFO oslo.messaging._drivers.impl_rabbit [-] Reconnected to AMQP server on ...
Actual result:
=ERROR REPORT==== 7-Jun-2016::10:08:46 ===
closing AMQP connection <0.15437.1> (10.249.21.40:37690 -> 10.249.21.39:5673):
{handshake_error,starting,0,
{amqp_error,access_refused,
"AMQPLAIN login refused: user 'guest' - invalid credentials",
'connection.start_ok'}}
Impact: Metering stops working
