DataSource recording zeroes for non-zero raw responses

FWIW: counter/derive datapoints will never show up right in a poll now because they don’t have the previous polls’ data and the time between it and a non-existent poll is non-existent. You might setup parallel datapoints that are counter with the same source and watch it over time to see what you get and which one makes more sense.

This is a multi-instance DS. Is it using script or batchscript mode? What does your datapoint definition look like?

Ok, cool. Script it is then. That should be fine.

Regardless of whether the documentation gives a timeframe, gauge might be the right thing to do. Derive and counter both take the delta from the previous poll and divide by the expected poll rate between them. If the result of your poll is 5960 and that’s the number you’re expecting to see, then you should use gauge. Counter would take 5960 from the current poll, and 5960 from the previous poll and find the delta (0). Then it would divide that delta by the poll rate between them, which would still give you 0. 

tl;dr only use counter/derive if you know the metric you are reading is actually a counter (like an odometer).

Still think you should try Gauge. If the result of the raw data is what you expect to see in the poll, then you should use gauge.

Oooh. Parallel datapoints is a great idea!

Dang it. @A11ey , please allow giphy.com as a domain so we can insert gifs.

I had to use the embed feature to get it to move. I checked their support site and this is apparently functioning as designed, but many others are saying that it works “sometimes”.  I used the embed on this one. 

I have not tried gauge. It doesn’t make sense to me to use gauge to count bytes across an interface. The API does not indicate that there is a time frame for a polling period (i.e. bytes in last 60 seconds).

The datasource is of type “script”. There too many VPN tunnels and “batchscript” times out.

I’m currently polling every 15 minutes. Could the issue be that I need a more frequent polling period?
