Understanding Event Messages

Add your section content here.This section describes the various types of event messages generated by the Server Administrator. When an event occurs on your system, Server Administrator sends information about one of the following event types to the systems management console:

Table 1. Understanding Event Messages . The following table provides information about event messages
Icon	Alert Severity	Component Status
	OK /Normal / Informational	An event that describes the successful operation of a unit. The alert is provided for informational purposes and does not indicate an error condition. For example, the alert may indicate the normal start or stop of an operation, such as power supply or a sensor reading returning to normal.
	Warning / Non-critical	An event that is not necessarily significant, but may indicate a possible future problem. For example, a Warning/Non-critical alert may indicate that a component (such as a temperature probe in an enclosure) has crossed a warning threshold.
	Critical / Failure / Error	A significant event that indicates actual or imminent loss of data or loss of function. For example, crossing a failure threshold or a hardware failure such as an array disk.

Server Administrator generates events based on status changes in the following sensors:

Temperature Sensor — Helps protect critical components by alerting the systems management console when temperatures become too high inside a chassis; also monitors the temperature in a variety of locations in the chassis and in attached system(s).
Fan Sensor — Monitors fans in various locations in the chassis and in attached system(s).
Voltage Sensor — Monitors voltages across critical components in various chassis locations and in attached system(s).
Current Sensor — Monitors the current (or amperage) output from the power supply (or supplies) in the chassis and in attached system(s).
Chassis Intrusion Sensor — Monitors intrusion into the chassis and attached system(s).
Redundancy Unit Sensor — Monitors redundant units (critical units such as fans, AC power cords, or power supplies) within the chassis; also monitors the chassis and attached system(s). For example, redundancy allows a second or nth fan to keep the chassis components at a safe temperature when another fan has failed. Redundancy is normal when the intended number of critical components are operating. Redundancy is degraded when a component fails, but others are still operating. Redundancy is lost when there is one less critical redundancy device than required.
Power Supply Sensor — Monitors power supplies in the chassis and in attached system(s).
Memory Prefailure Sensor — Monitors memory modules by counting the number of Error Correction Code (ECC) memory corrections.
Fan Enclosure Sensor — Monitors protective fan enclosures by detecting their removal from and insertion into the system, and by measuring how long a fan enclosure is absent from the chassis. This sensor monitors the chassis and in attached system(s).
AC Power Cord Sensor — Monitors the presence of AC power for an AC power cord.
Hardware Log Sensor — Monitors the size of a hardware log.
Processor Sensor — Monitors the processor status in the system.
Pluggable Device Sensor — Monitors the addition, removal, or configuration errors for some pluggable devices, such as memory cards.
Battery Sensor — Monitors the status of one or more batteries in the system.
SD Card Device Sensor — Monitors instrumented Secure Digital (SD) card devices in the system.
