System resource monitoring

System resource monitoring enables you to monitor your system's RAM, flash, memory, and CPU.
You can use the sysMonitor command to perform the following tasks:
•
•
Switch policies
Switch policies are a series of rules that define specific health states for the overall switch. Fabric
OS interacts with Fabric Watch using these policies. Each rule defines the number of types of errors
that transitions the overall switch state into a state that is not healthy. For example, you can specify
a switch policy so that if a switch has two port failures, it is considered to be in a marginal state; if it
has four failures, it is in a down state.
You can define these rules for a number of classes and field replaceable units, including ports,
power supplies, and flash memory.
See
See
the switch policy report.
Virtual Fabric support
Fabric Watch can monitor the switch health on eight logical switches. You can configure thresholds
and notifications for ports that belong to a particular logical switch. Each logical switch has its own
Fabric Watch configuration and triggers notifications based on its local configuration.
Fabric Watch supports port movement from one logical switch to another. Whenever a port is
moved, thresholds associated with the port are deleted from the logical switch the port was moved
from, and created for the logical switch to where the port is moved.
A logical interswitch link (LISL) is the logical portion of the physical connection that joins base
switches. You can enable or disable port thresholds and create thresholds for state changes on
LISLs, but Fabric Watch does not support other threshold areas such as link loss or signal loss for
LISLs as it does for normal E_Ports. See
changes that are allowed on an LISL.
NOTE
Only state changes are supported on LISL ports.

default settings, refer to

Configure thresholds for Fabric Watch event monitoring and reporting for the environment and
resource classes. Environment thresholds enable temperature monitoring, and resource
thresholds enable monitoring of flash memory.
Configure memory or CPU usage parameters on the switch or display memory or CPU usage.
Configuration options include setting usage thresholds which, if exceeded, trigger a set of
specified Fabric Watch alerts. You can set up the system monitor to poll at certain intervals and
specify the number of retries required before Fabric Watch takes action.
