Monitoring WLM with EMS

WLM provides an EMS monitor to track the workloads’ SLO compliance

and WLM itself. EMS can also report the status and values of WLM

metrics. You can configure EMS to send notification of items such as SLO

performance. The monitor places this data in the standard EMS

registrar for access from SAM, SMH, HP OpenView operations for unix,

and other EMS clients.

Figure 10-7 illustrates the role of EMS in using WLM.

What EMS resources are available?

The WLM EMS monitor, /opt/wlm/lbin/wlmemsmon, provides

information on how well WLM and the managed applications are

performing. wlmemsmon monitors the WLM daemon wlmd and provides

EMS resources for an EMS client to monitor. The EMS client can also

receive event notification periodically, when a value changes, or when a

value crosses some threshold. For more information on EMS capabilities

or operational paradigm, see the Using the Event Monitoring Service

manual.

Table 10-1 provides a quick reference for the EMS resources that WLM

provides. For more detailed information, see the sections following the

table.
