proc, procfix and automated restart of failed process

I've done a little archival reading and understand that the proc
directive specifies which process to look for (under essentially a 'ps
-e | grep procname' format).

 

The procfix directive then names what command to run, and here's the
key, when the associated prErrFix.# flag is set to 1 using snmpset.

 

My question, and the logical one that follows I believe, is...how does
one go about automating the execution of said snmpset command upon given
process failure?

 

Secondly, while I see alert trigger when I restart snmpd, why do I not
see it trigger when I kill the process while snmpd is up and running?

 

Here are the relevant portions of my snmpd.conf file:

 

monitor -u citadelInternal -r 60 -o prNames -o prErrMessage "process
table" prErrorFlag != 0

 

proc ntpd 1

procfix ntpd /sbin/service ntpd restart

 

 

And here is some related output from snmpwalk and snmpset:
