System Monitor support on Network OS VDX platforms

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.
• Limit — Specifies the default CPU limit. When the limit is exceeded, System Monitor sends out a
RASlog WARNING message. When usage returns below the limit, System Monitor sends a
RASlog INFO message. Valid values range from 0 to 80 percent, and the default value is
different for different systems.
• Low_limit — Specifies a lower usage limit for memory as a percentage of available memory.
This value must be less than the value set by the -limit parameter. When memory usage
exceeds or falls below this limit, System Monitor generates a RASlog INFO message. The
default for all platforms is 50 percent.
SFP parameter monitoring
System Monitor monitors the SFP parameters shown in Table 82 .
TABLE 82 SFP parameter descriptions
SFP parameter Description Suggested SFP impact
Temperature Measures the physical temperature of the
SFP transceiver, in degrees Celsius. High temperature suggests the SFP
transceiver might be damaged.
Receive Power (RXP) Measures the amount of incoming laser, in
uWatts. Describes the condition of the SFP
transceiver. If this parameter exceeds the
threshold, the SFP transceiver is
deteriorating.
Transmit Power (TXP) Measures the amount of outgoing laser, in
uWatts. Describes the condition of the SFP
transceiver. If this parameter exceeds the
threshold, the SFP transceiver is
deteriorating.
Current Measures the amount of supplied current
to the SFP transceiver. Indicates hardware failures.
Voltage Measures the amount of voltage supplied
to the SFP transceiver. A value higher than the threshold indicates
the SFP transceiver is deteriorating.
