log: set ident to openlog
at syslog side, log message is identified by its properties like programname, pid, etc. brick/mount processes need to be identified uniquely as they are different process of gluterfsd/glusterfs. At rsyslog side, log separated by programname/app-name with pid works but bit hard to identify them in long run which process is for what brick/mount. This patch fixes by setting identity string at openlog() which sets programname/app-name as similar to old style log file prefixed by gluster, glusterd, glusterfs or glusterfsd Change-Id: Ia05068943fa67ae1663aaded1444cf84ea648db8 BUG: 928648 Signed-off-by: Bala.FA <barumuga@redhat.com> Reviewed-on: http://review.gluster.org/5541 Reviewed-by: Vijay Bellur <vbellur@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com>
