Handling woth traps

[Pedro Henrique Morsch Mazzoni]

Hi!

I need to receive traps when some services has stoped.
My snmpd.conf on "clients" (agents) is like that:

rocommunity     public
rwcommunity     private

trapcommunity   public
trapsink        banff.lps.ufrj.br
trap2sink        banff.lps.ufrj.br


syslocation     lps2
syscontact      [EMAIL PROTECTED]

proc sshd
proc cupsd

disk    /       10%

How can I configure to the trapsink machine receive a trap when a service is not running?

Thanks,
Pedro Mazzoni
