All you need to know is the DS names for the rrd files. In fact, if you 
just use 'TARGET thatfile.rrd', then Weathermap will put a warning in 
the cacti.log with the possible ds names, for you. You can also just do 
'rrdtool info thatfile.rrd' to find the DS names.

There's more about this stuff here:

The only other caveat is that the scale is still a percentage. So pick a 
value beyond which *anything* is bad
(e.g. 1000ms) and set the BANDWIDTH to that. Then everything above that 
will be red, or whatever you set as 100% in your scale.

Other people have also used the rrds generated by Smokeping 
successfully, if you happen to use that too, and I have used the Cisco 
IP SLA cacti templates to do this too. Plenty of options. The final 
option, which is pretty untested, is to install fping, and use the fping 
datasource in Weathermap instead, and have it gather it's own data.
