Displays the health of the ExtremeXOS processes.
| name | Specifies the name of the process. |
N/A.
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 command is a resource for providing background system health information because you can view the health of ExtremeXOS 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.
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.
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.
To display the health of all processes on your system, use the following command:
show heartbeat process
The following is sample output from a Summit switch:

To display the health of the STP (Spanning Tree Protocol) process on your system, use the following command:
show heartbeat process stp
The following is sample output from the Summit switch:
Process Name Hello HelloAck Last Heartbeat Time ---------------------------------------------------------------------- stp 50870 50870 Tue Feb 10 05:22:13 2004
This command was first available in an ExtremeXOS 10.1.
This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X620, X690, X870 series switches.
