Hi Dave,
* Thanks for your valuable feedback.*

Please suggest me which method i need to follow whether DisMan Event MIB
or mib2c.notify.conf, for generating SNMPv2 traps ?
*Thanks in Advance*

The code template generated by 'mib2c.notify.conf' will give you a
routine that can be used to send a trap to the configured destinations.
But it's then up to you to decide *when* to call this routine, and hence
when to trigger the trap.
i.e. this routine provides _half_ of the code needed to send the trap.
It's purely concerned with how - not with when.
The DisMan Event MIB handles both what trap to send, *and* when
to do this. i.e. it handles both parts of the task.
(It's also built into the agent, so you don't need to write any code
yourself).

The third approach (which may well be the easiest) is not to try and handle
this within the agent at all.
Consider writing an external client command (perhaps as a simple perl
script), that queries the agent for the object(s) of interest, looks at the
values returned, and issues a trap when appropriate.
That's essentially what DisMan Event is doing - but embedded within the
agent rather than as an external command. Writing this yourself would give
you more control over exactly what conditions should trigger the trap.
