I’m using Cacti version 0.8.7i with Spine
I don't have access to the index table, but instead I have the ethPerformLastQHourChangeIndex
(This is the index number of the last entry in the ethPerformQHourTable. This index number refers to the ethPerformQHourPeriod index of the table.---This is the unique row number for the 15 minute period during
which this block of performance data was collected. ---No Access to this one )
The ethPerformLastQHourChangeIndex have this OID: .1.3.6.1.4.1.2509.8.42.2.1
When I do a snmpwalk : snmpwalk -v2c -c xxxx x.x.x.x .1.3.6.1.4.1.2509.8.42.2.1
I get this: .1.3.6.1.4.1.2509.8.42.2.1.0 = INTEGER: 24682
That represents the value of the counter that keeps increasing every 15 minutes. (the next will be: 24683)
In the ethPerformQHourTable, mentioned above, (This is an entry in the table containing the accumulation of the Ethernet performance counters during 15 minute period.) I have these parameters :
ethPerformQHourInUtilization which have the OID: .1.3.6.1.4.1.2509.8.42.2.20.1.22
(The average reception rate of packets on this port in the unit of 100 Kbps
for 15 minute period.)
ethPerformQHourOutUtilization which have the OID: .1.3.6.1.4.1.2509.8.42.2.20.1.23
(The average transmission rate of packets on this port in the unit of 100 Kbps
for 15 minute period.)
When I do a snmpwalk I get about 620 values, so I'll post the last ones.
snmpwalk -On -v2c -c xxxx x.x.x.x .1.3.6.1.4.1.2509.8.42.2.20.1.22.7

.1.3.6.1.4.1.2509.8.42.2.20.1.23.7.24677 = INTEGER: 2

.1.3.6.1.4.1.2509.8.42.2.20.1.23.7.24681 = INTEGER: 3
.1.3.6.1.4.1.2509.8.42.2.20.1.23.7.24682 = INTEGER: 4
The values I need to put on the graph as traffic In and Out are the last ones, in this example
.1.3.6.1.4.1.2509.8.42.2.20.1.22.7.24682 = INTEGER: 1
and
.1.3.6.1.4.1.2509.8.42.2.20.1.23.7.24682 = INTEGER: 4
these values correspond to the index that changes once in 15 minutes. Last value was: 24682
The XML looks like this:

The problem is that, the graph is not rendered.
I also tried to change the XML to check if the output values were returned. So just for debugging purpose I’ve changed the direction from output to input.
The Verbose Query looks like this:
So…the values are returned, but I’m afraid I’m missing something.+ Running data query [13].
