Do do the recent versions have a "description" better than this old one?: # Waiters, Monitor dn: cn=Waiters,cn=Monitor description: This subsystem contains information about read/write waiters. Despite of that: Have you considered introducing a "monitorGauge" for those? Also: is the value "right at the moment", or is it some sum or avarage for a time interval (like one second)?
