clients with different host name than uanme -n for xymon-4.2.2

hello,
   i am using different hostname for clients  than uname -n.hence i run
runcklient.sh with --hostname=myhostname and it is running fine and sending
data to server.But now whenever in future if runclient.sh gets stopped or
client process gets  killed,is ther any way to avoid running runclient.sh
with -hostname=myhostname mannually?where sholud i fix so that my
runclient.sh script always get"myhostname" and not the uname -n.i dont want
to change bb-hosts file CLIENT=hostname tag.
Any suggestions?
