Hi. Many thanks for your helpful and detailed explanation. I've fixed our monitoring to correctly use just pages_sharing to measure the savings. I think I just assumed the meanings of pages_shared and pages_sharing from their names. This means that ksm has been saving even more memory than we thought on our hosts in the past!
