The gauge option alerts MRTG to the fact that the graphed values are of the gauge type. If the value you are monitoring is in bytes, then you can convert the output to bits using the bits option.
Likewise, a hostname with no corresponding IPv6 address; it will not fall back to IPv4 if it simply fails to communicate with the target using IPv6., you can convert per second values to per minute graphs using the perminute Note that mrtg will only use IPv4 if you specify an IPv4 address This is by design.
