The monitor backend to slapd(8) is not an actual database; if
enabled, it is automatically generated and dynamically maintained by
slapd 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
These slapd.conf options apply to the monitor backend database. That
is, they must follow a "database monitor" line and come before any
subsequent "backend" or "database" lines.
As opposed to most databases, the monitor database can be
instantiated only once, i.e. only one occurrence of "database
monitor" can occur in the slapd.conf(5) file. Moreover, the suffix
of the database cannot be explicitly set by means of the suffix
directive. The suffix is automatically set to "cn=Monitor".
The monitor database honors the rootdn and the rootpw directives, and
the usual ACL directives, e.g. the access directive.
Other database options are described in the slapd.conf(5) manual
The usage is:
1) enable the monitor backend at configure:
2) activate the monitor database in the slapd.conf(5) file:
3) add ACLs as detailed in slapd.access(5) to control access to the
access to dn.subtree="cn=Monitor"
by dn.exact="uid=Admin,dc=my,dc=org" write
by users read
by * none
4) ensure that the core.schema file is loaded.
The monitor backend relies on some standard track
attributeTypes that must be already defined when the backend
