Description and usage of PutInfluxDB processor:

Processor to write the content of a FlowFile in ‘line protocol’. Please check details of the ‘line protocol’ in InfluxDB documentation (https://www.influxdb.com/). The flow file can contain single measurement point or multiple measurement points separated by line separator. The timestamp (last field) should be in nano-seconds resolution.

Properties:

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 Expression Language Guide, 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 nifi.properties file has an entry for the property nifi.sensitive.props.key.
