Monitoring Objects

Monitoring important objects in your system environment can help you detect problems

that can become unplanned outages.

Tools for Monitoring Objects

Monitor the states of important objects (processors, processes, disks, communications

lines, and files, for example), using:

•

Subsystem Control Facility (SCF)

•

CA-Unicenter for Tandem—Integrated Command and Control function (ICC)

•

Object Monitoring Facility (OMF)

Subsystem Control Facility (SCF)

You can use SCF commands like INFO, NAMES, STATS, and STATUS to display

information on the state of objects belonging to any subsystem that supports SCF. The

commands available for a particular subsystem’s objects are described in the SCF

reference manual for that subsystem.

For example, you can use the INFO, NAMES, and STATUS commands to query the

SUBSYS object $ZZKRN NonStop Kernel Subsystem manager or any of the PROCESS

object NonStop Kernel generic processes controlled by $ZZKRN. See the SCF

Reference Manual for the Kernel Subsystem.

You can use these same commands to monitor the status of storage devices (see the SCF

Reference Manual for the Storage Subsystem) and communications devices and lines

(see the SCF Reference Manual for the specific communications subsystem).

CA-Unicenter for Tandem—Integrated Command and Control Function (ICC)

You can use the ICC function of CA-Unicenter for Tandem to inquire about status of an

object with the click of a mouse button. Use ICC to substitute a common set of object

monitoring command buttons for the variety of corresponding subsystem commands,

thereby relieving operators of the need to know the syntax and peculiarities of individual

subsystem command interfaces.
