I have some APC SmartUPS's that I monitor with MRTG(I have SNMP cards in
them). I live in the US and we normally look at temperature in F. I am
running mrtg in rrd mode now and using routers2.cgi
I know the math can be done using this formula (((temp / 5) * 9) + 32),
but the data in the rrd databases is already in C and if I apply this to
the data as it's gathered, then the temperature is stored in F instead.
Not my first choice. Also, am not 100% certain that if I just put / 5 *
9 + 32, would that be applied to the data properly? This is not
something I want to play with on the fly here without some other opinions.
Or is there a way to apply the conversion to the graphs as they are
generated to convert from C to F?
