I only need an email if its greater than 90. I use

my final destination is monitor process
logical volume usage above X % and number of Logical voluage above

iwatch
IWATCH(1) General Commands Manual IWATCH(1)NAME
iwatch - a realtime filesystem monitor / monitor any changes in directories/files specified
SYNOPSIS
iwatch [options]
DESCRIPTION
This manual page documents briefly the iwatch command. iWatch is a realtime filesystem monitoring program. It's a simple perl script to
monitor changes in specific directories/files and send email notification immediately. It reads the dir/file list from xml config file and
needs inotify support in kernel (Linux Kernel >= 2.6.13).
OPTIONS
Usage for daemon mode of iWatch:
iwatch [-d] [-f <config file>] [-v] [-p <pid file>]
In the daemon mode iWatch has the following options:
-d Execute the application as daemon. iWatch will run in foregroud without this option.
-f <configfile.xml>
Specify alternative configuration file. Default is /etc/iwatch/iwatch.xml.
-p <pidfile>
Specify an alternate pid file (default: /var/run/iwatch.pid)
-v Be verbose.
Usage for command line mode of iWatch:
iwatch [-c command] [-e event[,event[,..]]] [-h|--help] [-m <email address>] [-r] [-s <on|off>] [-t <filter string>] [-v] [--version] [-x
exception] [-X <regex string as exception>] <target>
In the command line mode iWatch has the following options:
-c <command>
You can specify a command to be executed if an event occurs. For details about the string format take a look at
/usr/share/doc/iwatch/README.gz.
-C <charset>
Specify the charset (default is utf-8).
-e <event[,event[,..]]>
Events list. For details about possible events take a look at /usr/share/doc/iwatch/README.gz.
-h, --help
Print help message.
-m <emailaddress>
Contact point's email address. Without this option, iwatch will not send any email notification (obviously).
-r Recursivity of the watched directory.
-s on|off
Enable or disable reports to the syslog (default is off/disabled).
-t <filter>
Filter string (regex) to compare with the filename or directory name.
-x <exception file or directory>
Specify the file or directory which should not be watched.
-X <regex string as exception>
Specify a regex string as exception.
USAGE EXAMPLES
% iwatch /tmp
Monitor changes in /tmp directory with default events.
% iwatch -r -e access,create -m root@localhost -x /etc/mail /etc
Monitor only access and create events in /etc directory recursively with /etc/mail as exception and send email notification to
cahya@localhost.
% iwatch -r -c (w;ps -ef)|mail -s '%f was changed' root@localhost /bin
Monitor /bin directory recursively and execute the command.
% iwatch -r -X '.svn' ~/projects
Monitor ~/projects directory recursively, but exclude any .svn directories inside. This can't be done with a normal '-x' option
since '-x' can only exclude the defined path.
