Yes, i would like to set up an email monitoring whenever the DISK READ went above 600MB per second it will trigger an email to me personally.

I was able to get the output of 3 lines but not managed to create a logic when the read go above 600MB.

Code:
[root@xxxx ~]# iotop -bot --iter=3 |grep "Actual DISK READ"| awk {'print $5'}
127.99
151.71
157.06
[root@xxxx ~]#


ok using one second data might help.

Code:
[root@xxxx ~]# iotop -bot --iter=1 |grep "Actual DISK READ"| awk {'print $5'}
145.13
[root@xxxx ~]#

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
