Question

You need to run a kernel debug for an extended period because the issue occurs only once or twice each week. You therefore need to add a timestamp to the kernel debug and write its output to a file, but you cannot risk consuming all remaining disk space and have only 10 GB available to save the debug output. What is the correct syntax for this?

A fw ctl kdebug -T -f -m 10 -s 1000000 -o debugfilename
B fw ctl debug -T -f -m 10 -s 1000000 -o debugfilename
C fw ctl kdebug -T -f -m 10 -s 1000000 > debugfilename
D fw ctl kdebug -T -m 10 -s 1000000 -o debugfilename

Explanation

fw ctl kdebug -T -f -o <file> -m <count> -s <size> writes continuous, timestamped kernel-debug output into cyclic files. -m 10 creates ten cyclic files and -s 1000000 limits each to 1,000,000 KB, bounding storage at approximately 10 GB. Check Point documents -T for timestamps and -o together with -m and -s for cyclic output files.
