Sometimes mrtg at data acquisition from the SNMP-agent informs on a
error:
SNMP Error:

SNMPv1_Session (remote host: "x.x.143.2" [x.x.143.2].161)

SNMPGET Problem for ifDescr.2 ifInOctets.2 ifDescr.2 ifOutOctets.2 sysUptime
sysName on [EMAIL PROTECTED]::::::v4only
at /usr/local/mrtg-2/bin/mrtg line 1829
WARNING: Could not match host:'[EMAIL PROTECTED]' ref:'Descr'

ERROR: Target[zz][_IN_] ' $target->[39]{$mode} ' did not eval into defined data
ERROR: Target[zz][_OUT_] ' $target->[39]{$mode} ' did not eval into defined data
At that moment there is a peak equal approximately to half "MaxBytes"
parameter. If to have
time to look at present a file yy.log in the top line will be:
1074672962 -1 -1
I.e. for any reason SNMP counters for the input and output traffic are
equal -1
