Publishes Status events using the Site To Site protocol. The component type and name filter regexes form a union: only components matching both regexes will be reported. However, all process groups are recursively searched for matching components, regardless of whether the process group matches the component filters.


status, metrics, history, site, site to site


In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. The table also indicates any default values, whether a property supports the NiFi Expression Language, and whether a property is considered "sensitive", meaning that its value will be encrypted. Before entering a value in a sensitive property, ensure that the file has an entry for the property nifi.sensitive.props.key.
