I added one of my HP enclouser, and ran the ./discovery.php -h  it does not discover these :

Temperatures: 
Humidity : 
Voltages: 
Frequencies: 
Current: 
Power: 
Fanspeeds : 

how do i get these into my observium ?

also, 

is there a way to integrate total power in observium ? I get the total by snmpwalk :
snmpwalk -c public -v2c test01.local  enterprises.232.22.2.5.1.1.1.10 |awk '{ sum+=$4} END {print sum}' 

thank
