Directory Server supports monitoring through JMX, which is exposed by Java ES MF. See the Sun Java Enterprise System 5 Monitoring Guide for details on the interface itself.
The monitoring framework is contained within the Common Agent Container, cacao, which is installed alongside Directory Server. Figure 3–1 shows the monitoring framework. The information flow for JMX is similar to the flow shown for SNMP in Figure 3–2.
The monitoring information exposed through JMX is organized according to the Common Monitoring Information and Data Model, CMM. CMM allows applications exposing their monitoring information to associate human-readable descriptions with the individual counters and other information. CMM is therefore meant to be self-documenting. Directory Server implements the following CMM classes.
When examining the content of the monitoring information, notice that CMM_ServiceAccessURI is implemented not only for LDAP and for LDAPS, but also for DSML/HTTP or DSML/HTTPS if the DSML front end has been enabled.
Java ES Monitoring Console offers a browser-based user interface to examine the information exposed. See the Sun Java Enterprise System 5 Monitoring Guide for instructions on preparing the Monitoring Console for use.
