Collect values from events and send them to a logging stream. Typically used to create a XML or CSV file that logs temperatures or energy consumption
Description
This event handler collects values from incoming events and places these in data. Then typically on timed events the collection is passed through to a logging stream(s). This logging stream(s) may be either CSV or XML.
Configuration
The 'data' element of the event uses these parameters
- column This is the column number for CSV, it is mandatory and duplicates will generate an error
- name This is the XML tagname, this needs to be XML legal, it is mandatory and duplicates will generate an error
- attr This is the value to collect from the incoming event
