- Why I did it There is a issue for counters after warm-reboot: If I clear counters by command "sonic-clear counters", then execute 'warm-reboot' and whenSONiC is restart, the counters showed with command "show interface counters" is still old counters before "sonic-clear". It is not the right counters because the counters file in '/tmp' is lost in warm-reboot process. - How I did it I fixed it by saving '/tmp/portstat-0' folders in '/host/' before executing 'warm-reboot' (in pull request sonic-net/sonic-utilities#1099 ), and restore the counters folders back to '/tmp/' after warm-reboot process is finished. - How to verify it Clear counters by command 'sonic-clear' sonic-clear counters sonic-clear dropcounters sonic-clear pfccounters sonic-clear queuecounters sonic-clear rifcounters Execute 'warm-reboot' Use command ‘show interface counters’ to see if the counters is right.

- What I did
There is a issue for counters after warm-reboot:
If I clear counters by command "sonic-clear counters", then execute 'warm-reboot' and whenSONiC is restart, the counters showed with command "show interface counters" is still old counters before "sonic-clear". It is not the right counters because the counters file in '/tmp' is lost in warm-reboot process.
- How I did it
I fixed it by saving '/tmp/portstat-0' folders in '/host/' before executing 'warm-reboot', and restore the counters folders back to '/tmp/' after warm-reboot process is finished (in pull request sonic-net/sonic-buildimage#5346 ).
- How to verify it
Clear counters by command 'sonic-clear'
sonic-clear counters
sonic-clear dropcounters
sonic-clear pfccounters
sonic-clear queuecounters
sonic-clear rifcounters
Execute 'warm-reboot'
Use command ‘show interface counters’ to see if the counters is right.
