Doc Text:	.`ceph log last` does not display the exact number of specified lines The `ceph log last <number>` command shows the specified number of lines from the cluster log and cluster audit log, by default located at `/var/log/ceph/<cluster-name>/.log` and `/var/log/ceph/<cluster-name>.audit.log`. Currently, the command does not display the exact number of specified lines. To work around this problem, use the `tail -<number> <log-file>` command.	Story Points:	---

> `tail <number> <log-file>` command.

the command is 

tail -<number> <log-file>

and this is not accurate. for cluster log, <log-file> is by default /var/log/ceph/${cluster_name}.log, for audit log, /var/log/ceph/${cluster_name}.audit.log

they are configurable using "mon_cluster_log_file". in the form of 

default=/var/log/ceph/$cluster.$channel.log,cluster=/var/log/ceph/$cluster.log

see http://docs.ceph.com/docs/master/rados/troubleshooting/log-and-debug/.

Updating the QA Contact to a Hemant. Hemant will be rerouting them to the appropriate QE Associate.
