Monitor Description

The HP StorageWorks DS2500 Monitor (gazemon)  is designed to monitor the operations of the DS2500 storage enclosure on your system.

The gazemon monitor polls the device at regular intervals for the status of each disk array. If an error that warrants notification occurs on a disk enclosure or Just A Bunch Of Disks (JBOD) , the monitor sends the error details to the Event Monitoring Service (EMS) framework. Depending on the event monitoring requests, the EMS framework alerts the user about the event. Events include a description of the problem, its causes, and the recommended solution.

The monitor launches automatically when the system starts, ensuring that all supported disk enclosures are protected from undetected hardware failure.

Release History

The gazemon monitor is introduced in the HP-UX 11i v1 December 2006 release.

The monitor is introduced in the HP-UX 11i v2 June 2007 release on HP-UX 11i v2 systems.

Peripheral Status Monitor State Control

When the defective hardware is repaired, its state is changed to UP automatically by the Peripheral Status Monitor (PSM).

Configuration Files

The following sections describe the configuration files:

Startup Configuration File

The name of the Startup Configuration File (.sapcfg) is:
/var/stm/config/tools/monitor/gazemon.sapcfg

The monitor uses standard default monitor request entries.

Monitor Configuration File

The name of the monitor configuration file (.cfg) is:
/var/stm/config/tools/monitor/gazemon.cfg

The following table describes the default settings of the monitor configuration file:

Event Qualification Entry	Settings
POLL_INTERVAL	15 minutes
REPEAT_FREQUENCY	1440 minutes (1 day)
SEVERITY_ACTION	For information on specific events, see the .clcfg file.

PSM Configuration File

The name of the PSM Configuration File (.psmcfg) is:
/var/stm/config/tools/monitor/gazemon.psmcfg

The following table describes the default settings of the PSM Configuration File:

Setting Name	Details
MONITOR_RESOURCE_NAME	/storage/events/enclosures/gazemon
PSM_RESOURCE_NAME	/storage/status/enclosures/gazemon
MONITOR_STATE_HANDLING	UP_STATE_CONTROL When the defective hardware is repaired, its state is changed to UP automatically by the PSM. The set_fixed utility need not be used to change the state to UP.
DOWN_SEVERITY_THRESHOLD	CRITICAL maps to DOWN

Client Configuration File

The name of the Client Configuration file is:
/var/stm/config/tools/monitor/default_gazemon.clcfg

Multiple-View (Predictive-Enabled) monitors contain Client-Configuration files(.clcfg). Starting with the HP-UX 11i v1 December 2006 release, thegazemon monitor supports the Multiple-View (Predictive-Enabled)feature. You can modify the .clcfg files to control the text sent todifferent targets. The default_gazemon.clcfg file applies to messages sent to all targets. You can use the monitor-specific .clcfg files to control the text sent to specific targets. For example, in the predictive_dm_core_hw.clcfg file, you can control the text sent to Predictive Support.

You can enable the HOST_ID tag for all the monitors. For information on the HOST_ID tag, see the Generic Monitor Data Sheet at:
http://www.docs.hp.com/en/diag/ems/emd_generic.htm

The DEV_ID tags in the .clcfg files control monitor-specific information reported as Component Data in the event message. If you enable the DEV_ID tag in the .clcfg file, the corresponding information appears in the event message.

The following table provides information on DEV_ID for the gazemon monitor:

DEV_ID tag	Default	Text Label
dev_pdev	Off	Physical Device Path
