backend to slapd
(8) is not an actual database; if
enabled, it is automatically generated and dynamically maintained by
with information about the running status of the daemon.
To inspect all monitor information, issue a subtree search with base cn=Monitor,
requesting that attributes "+" and "*" are returned. The
monitor backend produces mostly operational attributes, and LDAP only returns
operational attributes that are explicitly requested. Requesting attribute
"+" is an extension which requests all operational attributes.

That is, they must follow a "database monitor" line and come before
any subsequent "backend" or "database" lines.

in the slapd.conf
(5) file. Moreover, the suffix of the database cannot
be explicitly set by means of the suffix

The usage is:
- 1) enable the monitor backend at configure:

control access to the database, e.g.:
access to dn.subtree="cn=Monitor"
by dn.exact="uid=Admin,dc=my,dc=org" write
by users read
