what is the command in Linux

It’s a command in linux, to check for system performance, which will cause the system to reboot writing every thing (what happens during the shutdown and in the startup) into a log which can be placed in a tar file.

If you install the sysstat package, you will get:

sar
iostat
mpstat

Sar will log performance metris to /var/log/sa

Then you have

vmstat
top

Maybe you are thinking of bootchart.

or diskstat

or perhaps the boot.log file found in /var/log on RH systems.

for boot process you can use dmesg.
for performance monitoring you can use sar or top
