System Monitor support on Network OS VDX platforms 14

•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 46.

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.
