found check_crm script on nagios exchange, it's not ideal, but again, since this
functionality doesn't come with pacemaker yet, you would have to invent your own
wheel ;)

Hi Vadym Chepkov 

Thanks for giving the reply. As mentioned i am trying to configure MailTo RA
with the Heartbeat from the command line 

i used the following configuration to configure it on the Heartbeat.

primitive mail ocf:heartbeat:MailTo \
        params email="<emailid>" \
        params subject="ClusterFailover"

and tried to restart the HA process using /etc/init.d/heartbeat restart

when i do crm_mon

it is unable to start MailTo process and digged into the ha-debug file and found
the related information

can u give some heads up on this issue so that i can proceed further.

bash-3.2# cat ha-debug | grep MailTo
May 26 10:34:39 hatest-msf3 pengine: [18575]: notice: native_print: mail
