io-stats: Add stats for upcall notificationsv3.10dev
With this patch, there will be additional entries seen in the profile info: UPCALL : Total number of upcall events that were sent from the brick(in brick profile), and number of upcall notifications recieved by client(in client profile) Cache invalidation events: ------------------------- CI_IATT : Number of upcalls that were cache invalidation and had one of the IATT_UPDATE_FLAGS set. This indicates that one of the iatt value was changed. CI_XATTR : Number of upcalls that were cache invalidation, and had one of the UP_XATTR or UP_XATTR_RM set. This indicates that an xattr was updated or deleted. CI_RENAME : Number of upcalls that were cache invalidation, resulted by the renaming of a file or directory CI_UNLINK : Number of upcalls that were cache invalidation, resulted by the unlink of a file. CI_FORGET : Number of upcalls that were cache invalidation, resulted by the forget of inode on the server side. Lease events: ------------ LEASE_RECALL : Number of lease recalls sent by the brick (in brick profile), and number of lease recalls recieved by client(in client profile) Note that the sum of CI_IATT, CI_XATTR, CI_RENAME, CI_UNLINK, CI_FORGET, LEASE_RECALL may not be equal to UPCALL. This is because, each cache invalidation can carry multiple flags. Eg: - Every CI_XATTR will have CI_IATT - Every CI_UNLINK will also increment CI_IATT as link count is an iatt attribute. Also UP_PARENT_DENTRY_FLAGS is currently not accounted for, as CI_RENAME and CI_UNLINK will always have the flag UP_PARENT_DENTRY_FLAGS Change-Id: Ieb8cd21dde2c4c7618f12d025a5e5156f9cc0fe9 BUG: 1371543 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/15193 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Rajesh Joseph <rjoseph@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>
