Hi all,
I have a table showing Link Statistics (e.g., Rx Bit Rate, Tx Bit Rate, Round Trip Time, Lost Packets, etc.) with trending enabled. The values are displayed correctly while the input is connected.
However, after some time, when the device input is unplugged, all table values disappear — which I understand is expected since the device stops reporting.
My question is:
Where can I find or view the historical status and trending data for these Link Statistics parameters, even after the current values disappear from the table?
In some cases, I might never use that specific input again, but I’d still like to review its past performance data.
When a row disappears from the table it is not possible anymore to open the trending easily from the table as you can when the row is there. The suggestion from Steve provides you with a way to access it still but might not be that trivial for operators mainly working from Cube. If this is something you need a lot for your day-to-day operations, then I would advise you to raise a feature request for the connector under your maintenance contract with Skyline on that specific connector to retain the rows if the input is lost/disconnected.
The reason why the row disappears is most likely because this table is filled based on retrieved data from the device, so if the row is no longer present in the result of the device, then the row is removed from the table. For monitoring purposes, it could be that a row disappears unexpectedly from the device and that you want to know about this (e.g. loss of input signal), in those cases we can retain previous rows and if those are no longer returned, then we can mark them as missing with an option to remove that row (or multiple) with a button or context menu. To be able to implement this, we must have a unique identifier of the device to be able to match rows between different results.
