sysdig logdata incomplete, when I specify the log information and output format

[codingjin]

According to the manual, I define my output format, and use the sysdig command in this way:
sysdig -p "%evt.num %evt.time name=%proc.name pid=%proc.pid <exe %proc.exe /exe> cwd=%proc.cwd dir=%evt.dir syscall=%syscall.type <args %evt.args/args> fd=%fd.num fd_type=%fd.type fd_name=%fd.name" -w log01

But I find the log is incomplete, like I cannot find the clone, syscall events, as I expected.
And I can find more information, like the expected clone event, in the default way, like just typing sysdig.

sysdig version 0.26.4
Operating System: Ubuntu 18.04.4 LTS

Same problem happens to me. Strange thing is i used to collect some information, but now even though i did not change sysdig script, the log is incomplete.
