We still use MRTG as a part of Nagios and Cacti in our monitoring systems but I haven't done any manual configs in a very long time. One common thing to keep in mind is that although NICs are generally specified in bits-per-second, SNMP (and consequently mrtg) use bytes- per-second. One gigabit IS 125,000,000 bytes (1,000,000,000 / 8 = 125,000,000). The MaxBytes option simply tells mrtg that values above this are to be ignored (ditto with AbsBytes). The primary idea is for mrtg to ignore nonsensical data which sometimes happens. I don't know if cfgmaker permits you to specify the "Thresh[Min|Max]*" options. That may still be a "manual, go hack the config yourself" step as it was back in the day (and a common reason people use Cacti (it allows you to set thresholds relatively easily through its GUI). ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - BASIC is the Computer Science version of `Scientific Creationism' - ---------------------------------------------------------------------- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
