ctm 1.2 – CTM is an SNMP interface statistics gatherer which works as a daemon and polls SNMP capable routers in regular intervals and puts the gathered information into a database. Information gathered includes operational status of the interface, octets and packets sent and received, line errors, and queue discards, but CTM can easily be changed to log any interface specific SNMP variable. CTM comes with an example report script which gives traffic and line error summaries for certain periods of time.
