Report: Find 'holes' in monitoring

Hi everyone, I would like to make a report to have evidence of possible 'holes' in polling data collection.

The ideal would be something that shows all nodes for which 10 consecutive polling cycles have failed, maybe with details on how many those skipped polling cycles are and when did it happened.

Is this a possible thing (do we have such information hidden somewhere in the database)? I can get instant values on that watching the 'now' date vs the last sync, but I can't do something on the historical values.

Any help would be much appreciated.

Thanks.
