Ensure that you are at least on NPM 9.5 and above, as there are known issues on Transforming COUNTER OIDs.
Note that the delta values will not be seen straight on the UnDP Console, but rather... it is seen on the Web Console (if you used Web Display)
Those values that are being shown in UnDP console are actually RAW values.
Can you post an example? I have plenty of counters that do not result in delta being displayed in the web console. It is my understanding there is no facility to do so for UnDP. That is why I requested the ability to call an external program via UnDP.
I had to create my own custom interface traffic graph, because the hardware vendor in question doesn't fully support RFC1213 MIB (which from the looks of it Orion uses stuff from here to verify if it can generate traffic graphs). This caused Orion to not create interface statistics on it's own for these devices, so I had to use this work around. I am using Orion NPM 10.0.0
MIB Val: Counter
SNMP Get: GET
Polling Type: Interface
*** NOTE ***
When you test your numbers in the poller, and transform tool it will show you the whole number, and not delta between the last 2 polls. This is where I was getting confused. When you add the poller to a device, and view it from the web page it will do delta for you, and show correct data if your formula is correct. I hope this makes sense...
You are correct the web page does show delta, and I was able to get this working with the poller/transforms I created.
