Check heatbeat from HAL process

[andre.godoy]

Hey Guys,

I'm facing the bug CSCvo45816,  where the switch has been up for a long time (607 days in my case). Once our timer (32-bit integer) wraps around, the Hal process will see this as a missed heartbeat and reload the switch.

The workaround is run  "vsh_lc -c 'debug platform internal hal infra thread heartbeat disable'" in all leafs.

Do you guys know how I can confirm if the thread heartbeat was disabled?

Thank you!

I recently had this answer

On the leaf, with root privilege,

cat /var/sysmgr/tmp_log/csco_hai_sb255_svc12_wk0_nub.log | log_decode | tail

If it's enabled, you will see the "punched HB" logs regularly. OR if it is disabled, you will see no output…
