[mrtg] missing data from one datasource

[Neil Lathwood]

Hi Folks,

Currently running mrtg 2.15.2 on a CentOS 5 box using rrd as a backend.
Everything works fine for the most, data is being collected fine and graphs
generated fine. However every so often the graphs will stop generating from
one of the datasources, if I enable logging for the rrd updates I get the
following:

2007-07-04 09:25:24 -- --log: RRDs::tune(/home/mrtg/switch1_16.rrd -a
ds0:1250000 -a ds1:1250000 -d ds0:COUNTER -d ds1:COUNTER)
2007-07-04 09:25:24 -- --log: RRDs::update(/home/mrtg/switch1_16.rrd,
'1183536660:4171765168:2798801761')
2007-07-04 09:25:24 -- --log:  got: ???/188391.226222222

It seems to be getting the required information from SNMP:

2007-07-04 09:24:46 -- --snpo: run snmpget from
ifInOctets&ifOutOctets:public at switch1
2007-07-04 09:24:46 -- --snpo: simple If: .16
2007-07-04 09:24:46 -- --snpo: simple If: .16
2007-07-04 09:24:46 -- --snpo: SNMPGet from public at switch1: -- ifInOctets.16
,ifOutOctets.16
2007-07-04 09:24:46 -- --snpo: SNMPfound -- '4133259110', '2946959781'

After a while (not a set time) the datasource will start to get updated
again.

Any clues on how to check/debug this problem?

Thanks.

Neil
