Commands for Status Monitoring and Statistics
show heartbeat process
show heartbeat process {<name>}
Description
Displays the health of the ExtremeWare XOS processes.
Command Syntax
Default
N/A.
Usage Guidelines
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
show heartbeat process
command displays the following information in a tabular format:
• Card—The name of the card where the process is running
• Process Name—The name of the process
• Hello—The number of hello messages sent to the process
• HelloAck—The number of hello acknowledgement messages received by the process manager
• Last Heartbeat Time—The timestamp of the last health check received by the process manager
(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.
Example
To display the health of all processes on your system, use the following command:
show heartbeat process
The following is sample output from this command:
Card Process Name Hello HelloAck Last Heartbeat Time
