Important things to note about maximum resource limits
By default the collector harvests metadata from Azure Data Lake Storage Gen 2 with up to 10,000 objects in each Storage Account. If your Azure Data Lake Storage Gen 2 has more than 10,000 objects in a given Storage Account, you must set the --max-resource-limit parameter to what you want. The max value can be set to 10 million. If the contents of a Storage Account cross this maximum limit, the Storage Account is skipped and a warning message is logged for the Storage Account.
