I'm trying to get the quality stored in the interal history provide. How could I see that?

Thanks in advance!

It's stored in the Ignition Database Table Reference | Ignition User Manual sqlth_1_yyyy_mm datatable in the dataintegrity column. 192 is good!

The system.tag.queryTagHistory | Ignition User Manual function doesn't return the quality but you can call it with ignoreBadQuality = True to force it to ignore garbage. The linked page says:

ignoreBadQuality A boolean flag indicating that bad quality values should not be used in the query process. If set, any value with a "bad" quality will be completely ignored in calculations and in the result set. [optional]

Thanks! Yout actually guided me the right way.

I founded the internal historian tables and transformed those to csv, then I analized all the quality.

Thanks Transistor!
