Alerts in OMCI
Alerts are generated when a system’s state of interest changes. There are two basic types of alerting: local alerting to the current computer user and remote alerting to a management application. Dell OpenManage
Client Instrumentation (OMCI) handles both types of alerting.
Note: Alerts are supported only in the standard namespace.
The Distributed Management Task Force (DMTF) has released the Alert Standard Format (ASF), which defines alerting and remote control interfaces that enable management of networked systems when their operating
system is absent. This includes a networked computer that has an inactive or inoperable operating system or that is in a low-power system sleep state. The ASF specification is available at www.dmtf.org. ASF
documentation is provided with Dell systems that support ASF.
ASF handles remote alerting for environmental events, which are detected by sensors, such as temperature, electrical, and fan probes, and chassis intrusion sensors. ASF also handles additional alerting in the operating-
system-absent environment. By default, OMCI handles remote alerting for all events.
ASF 2.0 adds important security measures to the ASF standard, which defines alerting and remote control interfaces to proactively manage networked devices when their operating system is absent. The first industry
specification for operating system absent management, ASF allows a network administrator to be alerted to failures of specific components within a networked device, thereby minimizing on-site maintenance while
maximizing remote visibility of and access to local systems. Without ASF, operating system absent problems require manual intervention to force a reboot of the system.
There are three settings in the system BIOS that OMCI allows for configuration:
Off — All ASF 2.0 features are turned off
Alert Only — ASF 2.0 alert is the only feature that is turned on
On — Alerts and remote control are turned on
The system network interface card (NIC) and basic input/output system (BIOS) support ASF 2.0. If the BIOS allows for any ASF 2.0 configuration, then the BIOS settings are exposed through the Microsoft Windows
Management Instrumentation (WMI) by OMCI.
OMCI Alerting
Local alerting involves displaying user messages and writing to the Windows event log. Remote alerting is accomplished through WMI indications. When OMCI detects an event, it generates an alert, which can be
transmitted through the WMI service to a remote management application that is subscribed to that alert type.
When an alert is generated, OMCI supports three types of notification:
NT event log
Remote
Console
In OMCI, each type of event (for example, CurrentProbe, TemperatureProbe, Smart, and so on) that gets logged is provided with an unique event ID number. The events have unique IDs to allow log scraping; this way
you can programmatically look at the event log and determine what OMCI events have occurred.
You are also provided with an option to receive either a single alert or a limited number of alerts of the occurrence of an event, of a given type. You can mask out specific events and can generate single alert messages
for only those events. The Dell_IndicationStaticValues class has the MaxNTEventLogNotifications, MaxDisplayNotifications, and the OccurrencesCount properties, which control the number of notices of each alert
condition that are sent to the NT event log and to the local display. For example, setting a value of 0 will not send any notices.
You can change any attribute or CIM class through standard CIM editors. The following properties in the Dell_IndicationStaticValues class control the number of notifications of each alert condition that are sent to the NT
event log and to the display. You can modify the below listed values through standard CIM editors or through scripts.
MaxNTEventLogNotifications: The maximum number of event notifications sent to the NT event log. Values are 0=never send, 1=first occurrence only, 2=first and second occurrences, and so on. The special
value of –1 sends all occurrences. The default value is –1.
MaxDisplayNotifications: The maximum number of event notifications sent to the local display. Values are 0=never send, 1=first occurrence only, 2=first and second occurrences, and so on. The special value of
–1 sends all occurrences. The default value is –1.
OccurrencesCount: The number of event notifications of the given alert that have occurred since the last reset. The initial value is 0. Setting OccurrencesCount to 0 restarts the sending of notices.
Since the instances of the Dell_ IndicationStaticValues class are stored in the WMI repository, the above data is persistent across shutdown, restart, sleep, hibernate, and standby modes. You can reset the
OccurrencesCount at reboot by installing a script to run at startup.
Note: You are not allowed to make changes to some properties including the MaxDisplayNotifications and MaxNTEventLogNotifications in the Dell_IndicationStaticValues class in the CIM repository unless the User
Account Control (UAC) in Windows Vista is turned off, or the user is the Administrator account.
The following properties in the Dell_Configuration class allows you to control the notices sent to the NT event log and to the local display based on the severity of the event:
GlobalNTEventLogSeverityLevel: Controls the notice to the NT event log based on the severity level of the event
GlobalDisplaySeverityLevel: Controls the notice to the local display based on the severity level of the event
OMCI recognizes the following eight WMI severity levels (represented by integers 0 through 7):
UNKNOWN = 0
OTHER = 1
INFORMATION = 2
