You can't make changes to the ViPR/C linux side of the house because they don't persist reboots.  I would suggest using a vmware tool or other enterprise tool that monitors ip's and or vm status.   
Hi VIPR C:  We have deployed a 5 VM Vipr Controller vAPP and want to use our internal monitoring tool - which will send an e-mail to us when the host is unreachable.    In order to do this, the Monitor Account 12345 has to be added to each VIPR C Linux VM.    Is this advisable?  I do not want to adulterate the LINUX OS.  Is there another way to be alerted that any of the 5 VM's is down?  We also have VIPR SRM, but have not implemented the VIPR C Solution Pack for SRM yet.  Thank you
