I created this small GIST about creating 5 thread dumps one after the other waiting for 10 seconds and then gzipping them and sending them using mutt. you can install mutt using yum or your prefer method.

email_threaddumps.sh

#! /bin/bash

#creating my folder to store them
if [ ! -d /tmp/`hostname` ]
then
    mkdir -p /tmp/`hostname`
fi

#executing my command
/usr/local/blackboard/tools/admin/ServiceController.sh services.appserver.threaddump
sleep 10
/usr/local/blackboard/tools/admin/ServiceController.sh services.appserver.threaddump
sleep 10
/usr/local/blackboard/tools/admin/ServiceController.sh services.appserver.threaddump
sleep 10
/usr/local/blackboard/tools/admin/ServiceController.sh services.appserver.threaddump
sleep 10
/usr/local/blackboard/tools/admin/ServiceController.sh services.appserver.threaddump

#move all the thread dumps to the temp location
mv /usr/local/blackboard/logs/tomcat/thread_dump* /tmp/`hostname`/

#gzip them
tar -zcvf `hostname`.gz /tmp/`hostname`

#email them
SUBJECT='Thread Dumps from '`hostname`
mutt -s $SUBJECT mail@mail.com -a /tmp/`hostname`.gz < text.txt
