NAME
slapd-monitor - Monitor backend to slapd
SYNOPSIS
/etc/ldap/slapd.conf
DESCRIPTION
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. Request-
ing attribute "+" is an extension which requests all operational attrib-
utes.
CONFIGURATION
These slapd.conf options apply to the monitor backend database. That
is, they must follow a "database monitor" line and come before any sub-
sequent "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 automat-
ically 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 page.
USAGE
The usage is:
1) enable the monitor backend at configure:
configure --enable-monitor
2) activate the monitor database in the slapd.conf(5) file:
database monitor
3) add ACLs as detailed in slapd.access(5) to 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
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 is started.
ACCESS CONTROL
The monitor backend honors access control semantics as indicated in
slapd.access(5), including the disclose access privilege, on all cur-
rently implemented operations.
KNOWN LIMITATIONS
The monitor backend does not honor size/time limits in search opera-
tions.
