Hello,
I need to trend parameter values from an interfaces table, that are on state "Up" only.
Do you have any advise on that?
Thank you.

Hi Bruno,
can you elaborate on the need for that? Because that would mean that you would track the performance data while it is up, and then stop it once it is down, and start it again when it goes up.
If the motivation is to save storage, I don't think it would have a lot of impact. Because if the port is down, the tracked metrics (like utilization, RX/TX bitrates,...) are static, and in that case the trend logging in DataMiner is smart enough not to continuously store those data points individually.
Just trying the understand the underlying thought for this question.

Thanks for your feedback. And yes, data polling and trending are two separate independent activities, i.e. it is not because you do not enable trending that the metric is not being polled (and it could also still be needed for alarming).
Hi Ben,
There are some interfaces in some “administrative” status (“unknown”, “testing”, etc) that I know it won’t be eligible for trending.
I was just trying to understand if we could leave them out to improve performance. (not only from a storage perspective but also from a “polling data retrieved from the device”.. but I guess you always get the values from the device, the trending would only choose to store it or not, right?)
By your answer and after thinking about it a bit more, I guess that the performance improvement would not be that much though.
Thank you.
Best regards
