Why can’t I see my tag which was recently added in the data source?
TrendMiner refreshes the data source tag cache every 24h from the moment the data source was added or the tm-datasource service was restarted. This means that updates to the list of available tags and their metadata (name, description, units and tag type) can take up to a day to take hold organically.
If you have recently changed tags in your data source and you wish for these changes to be reflected immediately, you can refresh the tag cache manually for a selected data source in ConfigHub as documented here.
