To enable the OpenLDAP-SPI monitor tools to work properly, perform the following steps.
1. Configure the monitor database of the respective LDAP server (OpenLDAP or CDS).
For example, add the following lines to the slapd.conf file:
# --- monitor backend
database monitor
access to dn.subtree="cn=Monitor"
by dn.exact="dc=example,dc=com" write
by users read
by * none
2. In the same file, slapd.conf, uncomment the line moduleload back_monitor.la.
3. Run the visudo command as root and comment out the line Defaults requiretty.
Event-Driven Methods
The event-driven methods are used to manage events that are triggered when certain conditions
are met, for example, if the CDS server process utilizes a greater percentage of CPU bandwidth
than the threshold defined in the policy. When a threshold is exceeded, warning messages appear
in the management console. Table 6 lists the CDS SPI policy details:
