[SOLVED]Generic OID not graphing in 0.8.7

[jrohr]

Hello,

I'm having problems getting a generic OID graph working in Cacti 0.8.7. Trying to get temperature data from a AVTech Room Alert. I first duplicated the "SNMP-Generic OID template", set data source name for the 2 OIDs I'm graphing. Then created a Graph Item Input for each of these in Graph Templates and created Template Items. Finally, added the graph to my device. At first I was getting 0 values returned, but now getting NAN's. I've gone through the Debug NaN's in graphs troubleshooter and everything checks out ok. I'm getting the following error in cacti.log:

"CMDPHP: Poller[0] Host[6] DS[37] WARNING: Result from SNMP not valid. Partial Result: "

---------------------

When turning on Graph Debug Mode RRDTool says OK (see below). Also, verified RRD files are correct.

RRDTool Command:

c:/rrdtool/rrdtool.exe graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="Room_Alert Temperature" \
--base=1000 \

LINE2:b#FFFF00:"External Temp" \
GPRINTLAST:"Current\:%8.0lf" \
GPRINTAVERAGE:"Average\:%8.0lf" \
GPRINTMAX:"Max\:%8.0lf\n"
RRDTool Says:

OK

----------------

Additionally, I can run a snmpget on the OID from a command line and get valid output.

C:\RRDTool>snmpget -v1 -c public <IP address> enterprises.20916.1.2.1.1.5.0
SNMPv2-SMI::enterprises.20916.1.2.1.1.5.0 = INTEGER: 73

C:\RRDTool>snmpget -v1 -c public <IP address> enterprises.20916.1.2.1.1.6.0
SNMPv2-SMI::enterprises.20916.1.2.1.1.6.0 = INTEGER: 71


Anyone had problems with generic OID templates or seen this before?

Thanks

Dump your poller_items table and post.

[jrohr]

Here's the poller_item data. I noticed the OIDs are not the entire number.
But in the data template it is the entire number
(i.e. .1.3.6.1.4.1.20916.1.2.1.1.6.0)

Do I need to recreate the data template or something else?

Try clearing your poller cache and see if the full OIDs are stored.

[jrohr]

I cleared the poller cache and now see the full OIDs in the poller_item table. But I'm still getting Partial Result warnings from cmd.php.

Alright, click on DS[37] and see what it points to. Look in your poller cache / snmp cache again to see what DS[37] is trying to poll for the OID. Is it correct?

[jrohr]

It's in the poller cache:

SNMP Version: 2, Community: public, OID: .1.3.6.1.4.1.20916.1.2.1.1.6.0
RRD: c:\Inetpub\wwwroot\cacti\rra\room_alert_ra_ext_temp_37.rrd

But nothing in the SNMP cache for that host except default ones like "SNMP - Interface Statistics". Should it be listed here as well?

[BSOD2600]

yes, it should be listed.

[jrohr]

Figured it out!

I had to remove the SNMP version from both Data Templates that I created. Thanks for the help.
