Im in the process of updating our network monitor.. Moving the entire
system to mrtg 2.16.x and rrdtool based logs.
I'm polling 5k+ devices in this new system..
I have some targets that will eval to no data (ie a switch port that no
one has used as of yet) My mrtg.log is littered with the below messages.
--- mrtg.log clip ----
2010-03-17 11:36:11 -- SNMPGET Problem for ifHCInOctets.201
ifHCOutOctets.201 on public at switch.our.net:::::2::v4only
at /usr/bin/mrtg line 2035
2010-03-17 11:36:11 -- Wednesday, 17 March 2010 at 11:30: WARNING:
skipping because at least the query for ifHCInOctets.201 on
switch.our.net did not succeed
2010-03-17 11:36:11 -- Wednesday, 17 March 2010 at 11:30: WARNING: no
data for ifHCInOctets&ifHCOutOctets:public at switch.our.net.
Skipping further queries for Host switch.our.net in this round.
2010-03-17 11:36:13 -- SNMP Error:
no response received
Are these the result of polls that return no data? Or is this a bad
Also is this indicating that it will skip polling the remainder of the
entire switch (the next N ports) or just the port that this warning was
Any help appreciated .. I'm still trying to make heads or tails of this
