rrd not update

[ging]

I added a cisco router and the rrd file successfully created.

I tried to run the cmd.php and got the following error....!!

snmp: c2621.hksps.com:161, dsname: traffic_in, oid: .1.3.6.1.2.1.2.2.1.10.1, value: interfaces.ifTable.ifEntry.ifInOctets.1 2683369377

ERROR: expected 2 data source readings (got 1) from N:interfaces.ifTable.ifEntry.ifInOctets.1:...

please help!!

I encountered the same problem with a lotus domino server.
The problem here is that the var being read not only contains the needed value but also returns the name of the oid.

So what I did is writing a script that strips off the name from the returned value and I used this as a data input method

by default, RH installed the ucd-snmp and it didn't work well with the cacti....

The problem was fixed after uninstalled the ucd-snmp and setting the snmp path to the net-snmp.
