You need to specify the full path to the su command. Monit sets a very spartan path variable which may not contain this command.

check host Remediation_Test with address
        group www
start program = "su - weblogic -c /opt/bea/user_projects/ domains/cap2test/start"

Write instead (assuming su is in /usr/bin):
start program = "/usr/bin/su - weblogic -c /opt/bea/ user_projects/domains/cap2test/start"

On a side note, monit also support user id and group id switch upon starting a program, if you run monit as root. That is you could also write the above as

start program = "/opt/bea/user_projects/domains/cap2test/ start" as uid weblogic and gid weblogic

See also the tomcat config example here, monit/doc/manual.php#configuration_examples

Monit will then run the server as the weblogic user.

start program = "cd /opt/bea/user_projects/domains/cap2dev; su weblogic -c \"nohup

The start/stop command only takes a program with arguments. You cannot run a script directly. If you want to run a script you must start a shell like so

start program = "/bin/bash -c 'cd /opt/bea/user_projects/ domains/cap2dev; su weblogic -c ..'

What I am trying to do is this:

Run some processes as another user (weblogic). So for that I use "su weblogic"
