When I tried it I get:

# ssh IP "top -d1"
root@IP's password:
TERM environment variable not set.

I added the -b option for batch mode and it works.

# ssh IP "top -b -d1"

thanks a TON man, the error got rectified. I can use it now.
But again,
can anyone explain why this error popped out.

The top utility usually runs in a graphics mode so it has to know the type of terminal, or more accurately, terminal emulator you're using. That's defined by the variable TERM. Under normal login it gets set to something like 'vt330' so top knows what escape sequences to use to move the cursor around on the screen.

I tried and got:
'# ssh IP "set" | grep TERM'
root@IP's password:
TERM=dumb

So it appears top doesn't know how to handle things when TERM is set to dumb. The '-b' option tells top to forget graphics and print output in straight text. Well, that's my somewhat educated guess.
