Hi,

My goal is to run pt-query-digest tool.

I first run on our Linux machine:  
tcpdump -s 65535 -x -nn -q -tttt -i any -c 9999999 port 3306 | gzip -c \> /tmp/tcpdump.txt.gz

Then I run:  
gunzip -c /tmp/tcpdump.txt.gz | ./pt-query-digest --type tcpdump \> /tmp/digest\_output.txt

With the second command, I am getting the following errors with PERL:

[root@ip-10-0-5-103 bin]# gunzip -c /tmp/tcpdump.txt.gz | ./pt-query-digest --type tcpdump \> /tmp/digest\_output.txt  
Can’t locate Time/HiRes.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor\_perl /usr/share/perl5/vendor\_perl /usr/lib64/perl5 /usr/share/perl5 .) at ./pt-query-digest line 3165.  
BEGIN failed–compilation aborted at ./pt-query-digest line 3165.  
[root@ip-10-0-5-103 bin]#

Any idea on how to solve this error message on PERL?

Thanks,  
Michel Z.
