Filter Plugins¶
Filter plugins add new ways in which data may be modified, enhanced or cleaned as part of the ingress via a south service or egress to a destination system. A number of north plugins are available ready built or users may add new north plugins of their own by writing them in Python or C/C++.
It is also possible, using particular filters, to supply expressions or script snippets that can operate on the data as well. This provides a simple way to process the data in Fledge as it is read from devices or written to destination systems.
