System Monitor support on Network OS VDX platforms
18
• 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 81 .
Security monitoring
System Monitor monitors all attempts to breach your SAN security, helping you fine-tune your
security measures. If there is a security breach, System Monitor sends a RASlog alert. The following
security areas are monitored:
• Telnet violation, which occurs when a Telnet connection request reaches a secure switch from
an unauthorized IP address.
• Login violation, which occurs when a secure fabric detects a login failure.
Port statistics monitoring
System Monitor monitors port statistics on all external Gigabit Ethernet interfaces: 1 Gb, 10 Gb,
and 40 Gb. When any monitored error crosses the configured high or low thresholds, an alert is
generated.
TABLE 81 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.
