调用 pt-diskstats 时报错如下Can't locate Time/HiRes.pm in @INC
[root@localhost ~]# pt-diskstats
Can't locate Time/HiRes.pm in @INC (@INC contains: /usr/local/lib/perl5 /usr/local/share/perl5 /usr/lib/perl5/vendor_perl /usr/share/perl5/ vendor_perl /usr/lib/perl5 /usr/share/perl5 .) at /usr/local/bin/pt-diskstats line 3108.
BEGIN failed--compilation aborted at /usr/local/bin/pt-diskstats line 3108.
解决办法，安装perl-Time-HiRes
yum install perl-Time-HiRes;
搞定。
