Writing Monitors for the Event Monitoring Service (December 1999)

60 Chapter3

Creating a Resource Monitor

Implementing a Resource Monitor

Follow these steps to write and install a resource monitor in the EMS:

Step 1. Write the monitor.

The rest of this chapter explains how to write a monitor using the EMS

API. The EMS API functions are explained in the chapter, “The EMS

Application Programming Interface (API).”

Step 2. Add the monitor to the resource dictionary.

The resource dictionary ﬁles are ASCII ﬁles that you can edit with any

text editor. The syntax of the resource dictionary ﬁles is explained in the

chapter, “Understanding the Event Monitoring Service.”

Step 3. Use the montest tool to test the conﬁguration and operation of your

resource monitor.

The montest tool is explained in the chapter, “Testing a Resource

Monitor with montest.”

Step 4. Conﬁgure an EMS client application to send monitor requests to the

Registrar.

Examples of EMS client applications are MC/ServiceGuard and the SAM

interface to EMS (the EMS framework product).

The manual Using the Event Monitoring Service (HP Part Number

B7612-90015) provides instructions for:

• conﬁguring the client application through the SAM interface to EMS.

• creating ServiceGuard packages that depend on EMS resources.
