Configure the crawler

Before running the Microsoft Azure Event Hubs crawler, you can further configure it.

  • To select the assets you want to exclude from crawling, click Exclude event hubs regex. (This will default to no assets, if none specified.)
  • To select the assets you want to include in crawling, click Include event hubs regex. (This will default to all assets, if none are specified.)
πŸ’ͺ Did you know? If an asset appears in both the include and exclude filters, the exclude filter takes precedence.

  • To run the crawler once, immediately, at the bottom of the screen, click the Run button.
  • To schedule the crawler to run hourly, daily, weekly, or monthly, at the bottom of the screen, click the Schedule & Run button.
