14 System Monitor support on Network OS VDX platforms

•Fan — Configures fan settings

•Power — Configures power settings

•Temp — Displays the threshold for the temperature sensor component

•CID-card— Displays the threshold for the CID card component

•SFP — Displays the threshold for the small form factor pluggable (SFP) device

•compact-flash— Displays the threshold for the compact flash device

•MM — Displays the threshold for the management module

•LineCard — Displays the threshold for the line card

•SFM — Displays the threshold for the switch fabric module

System thresholds

System Monitor monitors the health of each component and, based on the threshold value, each component can be in a marginal state or a down state. Possible states for all monitored FRUs are removed, inserted, on, off, and faulty. A state of none indicates the switch is not configured. If the FRU is removed, inserted, or goes into a faulty state, System Monitor sends a RASlog message or an e-mail alert.

Refer to the “RAS System Messages” chapter of the Network OS Message Reference for details about each RASlog message.

Alert notifications

System Monitor provides event notifications by way of RASlog messages or e-mail alerts, depending on the configuration.

•RASlog — If a component is in a marginal state or a down state, System Monitor generates a RASlog message to alert the user. It also generates a separate RASlog message for the overall health of the switch.

•Email — An e-mail alert sends information about a switch event to a specified e-mail address. The e-mail specifies the threshold and describes the event, much like an error message.

Resource monitoring

System Monitor monitors CPU and memory usage of the system and alerts the user when configured thresholds are exceeded. When the CPU usage exceeds the limit, a system monitor alert is triggered. The default CPU limit is 75 percent. When configuring memory, the limit specifies a usage limit as a percentage of available resources.

When used to configure memory, monitoring the limit value must be greater than the low limit and less than the high limit. Three thresholds are supported for memory monitoring:

•High_limit — Specifies an upper usage limit for memory as a percentage of available memory. This value must be greater than the value set by the -limit parameter. The maximum is 90 percent. When memory usage exceeds this limit, System Monitor generates a CRITICAL RASlog message. The default is 80 percent.
