Someone installed NMIS on a linux box that i have. I'm trying to add more *.rrd files into the box but it doesn't seem to acknowledge the rrdtool command, even though a directory exists.

How do i activate this command ?
I need to add more devices for monitoring purposes

see below:

root@kclinux:/# ls /usr/local/rrdtool/bin
rrdcgi rrdtool rrdupdate


root@kclinux:/# rrdtool create test.rrd
bash: rrdtool: command not found


Cheers
