OpenStack log files contains different structures and distributed across multiple folders which make a real challenge to provide real proactive insights on your deployment. Loom Cloud Intelligence can simply save your time and make sense of your Openstack deployment on going issues.
Most services use the convention of writing their log files to subdirectories of the /var/log directory, as listed in the following list.
Image Service glance-*
Block Storage cinder-*
Identity service keystone-*
/var/log/apache2 or /var/log/httpd
Orchestration service heat
Telemetry service ceilometer
All nodes misc (swift, dnsmasq)
Compute nodes libvirt
Compute nodes Console (boot upmessages) for VM instances: /var/lib/nova/instances/instance-/console.log
Block Storage nodes cinder-volume
How to confiugre logging in Openstack enviroment?
Separately configure the Compute service (nova), the Identity service (keystone), the Image service (glance), and, if you are using it, the Block Storage service (cinder) to send log messages to syslog. Open these configuration files:
In each configuration file, add these lines:
debug = False
use_syslog = True
syslog_log_facility = LOG_LOCAL0
In addition to enabling syslog, these settings also turn off debugging output from the log.
