Default
N/A.
Usage Guidelines
The software monitors all of the XOS processes running on the switch. This process monitor creates and
terminates XOS processes on demand (for example, when you log in or log out of the switch) and
restarts processes if an abnormal termination occurs (for example, if your system crashes). The process
monitor also ensures that only version-compatible processes and processes with proper licenses are
started.
The
show heartbeat process
information because you can view the health of ExtremeWare XOS processes on the switch.
Use this command to monitor the health of the XOS processes. The switch uses two algorithms to
collect process health information: polling and reporting. Both polling and reporting measure the
heartbeat of the process. Polling occurs when a HELLO message is sent and a HELLO_ACK message is
received. The two counts are the same. Reporting occurs when a HELLO_ACK message is sent only.
Therefore, no HELLO messages are sent and the HELLO count remains at zero.
The

●
(Unknown specifies kernel modules and they do not participate in heartbeat monitoring.)
This status information may be useful for your technical support representative if you have a network
problem.
You may find it useful to capture the process information under normal operating conditions to
establish a baseline. By having a baseline, if you experience a problem, you and your technical support
representative can more easily identify the problem.
