32 AlertsThe 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.ASF AlertingIn previous versions of OMCI, environmental alerts were sent as DesktopManagement Interface (DMI) alerts. With the introduction of ASF, theenvironmental alerts are handled by the ASF NIC. ASF monitors theenvironmental probes at a very low level and sends out a Platform Event Trap(PET) when an event occurs. Where applicable, OMCI notifies the local userof the alert. For information on which PET a specific model of Dell systemsupports, see the system's Setup Guide.ASF is a DMTF management standard that specifies "pre-operating system"or "operating system-absent" alerting techniques. The standard is designed togenerate an alert on potential security and fault conditions when theoperating system is in a sleep state or the system is powered off. ASF isdesigned to supersede previous operating system-absent alertingtechnologies.WMI AlertingLocal alerting involves displaying user messages and writing to the Windowsevent log. Remote alerting is accomplished through WMI indications. WhenOMCI detects an event, it generates an alert, which can be transmittedthrough the WMI service to a remote management application that issubscribed to that alert type.When an alert is generated, OMCI supports three types of notification:• NT event log• Remote• ConsoleIn OMCI, each type of event (for example, CurrentProbe, TemperatureProbe,Smart, and so on) that gets logged is provided with an unique event IDnumber. The events have unique IDs to allow log scraping; this way you canprogrammatically look at the event log and determine what OMCI events haveoccurred.
