Depending on your needs, use the following logging locations for the OpenStack services:
/var/log/remote/<NODE_HOSTNAME_OR_IP>/SERVICE_NAME.log./var/log/<SERVICE_NAME>-all.log file and the /var/log/<SERVICE_NAME>/
folder. Some OpenStack services, for example, Horizon and Ironic, have only
a log folder in /var/log/<SERVICE_NAME>/ and do not have a
/var/log/<SERVICE_NAME>-all.log file.Some OpenStack services have additional logging locations. The following table lists these locations:
| Service name | Log files location | 
|---|---|
| Corosync/Pacemaker | Fuel Master node: 
 | 
| Horizon | Controller node: 
 | 
| Keystone | Controller node: Since the Keystone service is available through the Apache server, the Apache logs contain the Keystone logs: 
 | 
| MySQL | Controller node: 
 | 
| Neutron | Controller node:
