Admin Monitor should anonymize the specific content of OldDataMonitor. This is a special case in the component https://github.com/jenkinsci/support-core-plugin/blob/ab510dc46b3db272b7b1a7f513884c52ff30ca8b/src/main/java/com/cloudbees/jenkins/support/impl/AdministrativeMonitors.java#L77 and it may contain information that should be filtered (item / node / user names).
