OpenStack services logging

OpenStack services logging¶

Depending on your needs, use the following logging locations for the OpenStack services:

On the Fuel Master node, the log files of all OpenStack services are located in /var/log/remote/<NODE_HOSTNAME_OR_IP>/SERVICE_NAME.log.
On each node of your environment, the log files are located in the /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: /var/log/remote/<NODE_HOSTNAME_OR_IP>/attrd.log /var/log/remote/<NODE_HOSTNAME_OR_IP>/crmd.log /var/log/remote/<NODE_HOSTNAME_OR_IP>/cib.log /var/log/remote/<NODE_HOSTNAME_OR_IP>/lrmd.log /var/log/remote/<NODE_HOSTNAME_OR_IP>/pengine.log
Horizon	Controller node: /var/log/apache2/horizon_access.log /var/log/apache2/horizon_error.log
Keystone	Controller node: Since the Keystone service is available through the Apache server, the Apache logs contain the Keystone logs: /var/log/apache2/error.log /var/log/apache2/access.log /var/log/apache2/keystone_wsgi_admin_access.log /var/log/apache2/keystone_wsgi_admin_error.log /var/log/apache2/keystone_wsgi_main_access.log /var/log/apache2/keystone_wsgi_main_error.log
MySQL	Controller node: /var/log/syslog
Neutron	Controller node: /var/log/openvswitch
