Monitor Event Router Daemon (erd) Events
About the xtconsumer command.
The HSS xtconsumer command enables the system administrator to monitor events mediated by the event router daemon erd, which runs passively.
Monitor for specific events
For this example, watch two events: ec_heartbeat_stop, which will be sent if either the node stops sending heartbeats or if the system interconnection network ASIC stops sending heartbeats, and ec_l0_health, which will be sent if any of the subcomponents of a blade controller report a bad health indication:
crayadm@smw> xtconsumer -b ec_heartbeat_stop ec_l0_health
Use the xthb command to confirm the stopped heartbeat. Use the xthb command only when actively looking into a known problem because it is intrusive and degrades system performance.
Check events except heartbeat
crayadm@smw> xtconsumer -x ec_l1_heartbeat
For more information, see the xtconsumer(8) and xthb(8) man pages.
