Of course. These are all OID's that only exist in three phase units.  
Your Smart-UPS 3000 XL is a single phase unit, so that won't  
report/support them. The development version will no longer log  
messages about missing OID's by default anymore, since they are not  
really errors, but informative messages (for developers) only. You can  
safely ignore them.

Note that the snmp-ups driver is an experimental driver. See also 'man  
8 snmp-ups' for what this means for you.

See 'man 8 upslog'. It will probably require some shell scripting, but  
it can be done.

Note that your UPS will miss short lived transient, so if you're  
looking for those, use a power quality analyzer. After all, a UPS is  
not a measurement instrument (tm).
