I have followed a number of tutorials online in trying to set this up but I was unsuccessful. Basically, I want all the logs in /var/log/nova/nova-compute to also be logged in another file through syslog. Here are the steps I followed:

1. Set up the two following options in nova.conf:

use_syslog = True
syslog_log_facility = LOG_LOCAL0

1. Restarted the openstack-nova-compute service

2. Added the following line in rsyslog.conf:

local0.* -/var/log/nova-all.log

1. Restarted the rsyslog service

The file nova-all never gets created, even if I try to set verbose=True and debug=True in nova.conf. I don't believe this is an issue with my rsyslog config because if I change the line: local0.* -/var/log/nova-all.log to *.* -/var/log/nova-all.log, the file will get created and logs will started generating. I think nova doesn't send it anything for some reason. I think all my nova.conf configuration is fine but I must be missing something. Any help would be greatly appreciated.
