Status UNKNOWN and no data in graphs

[Thomas Dorsch]

Hi,

i'm using nagios for a couple of days and it works great for me. This 
time i'm implementing the apan snmp plugin to get interface statistics 
from our cisco 's. After configuring it worked out of the box for one 
day. All graphs were produced fine but suddenly the state in nagios 
turned UNKNOWN and there were no more traffic graphs displayed. Below is 
the outputline of nagios service details and config samples also.

net_flow (my command definition)

UNKNOWN
12-05-2002 10:59:36
1d 19h 3m 54s
3/3
SNMP WARNING - Counter32: 3787811407 (this is still increasing but no 
data is displayed within the graphs)

This is the line in apan.cfg:

mycisco;net_flow;/usr/local/nagios/rrd/mycisco_net_flow.rrd;public:.1.3.6.1.2.1.2.2.1.10.3|public:.1.3.6.1.2.1.2.2.1.16.3;IN:LINE1 
OUT:LINE2;Network throughput;Bytes/sek; which is the eth0 interface on a 
cisco MC3810.

This is the commandline to create the rrd file:

rrdtool create /usr/local/nagios/rrd/mycisco_net_flow.rrd -s 60 
DS:IN:COUNTER:300:0:U DS:OUT:COUNTER:300:0:U RRA:AVERAGE:0.5:1:50400 
RRA:AVERAGE:0.5:60:43800

Any idea what could be the problem. I tried a couple of things 
especially with heartbeat and also changed COUNTER to DERIVE, but the 
problem is still the same.

Regards Tom
