|
|
* Add top level tests
* Add a skeleton for preparing buffers
* Initialize graphite instance
* Prepare buffers for all instances
* Add Grafite collected value formatter
* Add support for exporting.conf read and parsing
* - Use new exporting_config instead of netdata_config
* Implement Grafite worker
* Disable exporting engine compilation if libuv is not available
* Add mutex locks
- Configure connectors as connector_<type> in sections of exporting.conf
- Change exporting_select_type to check for connector_ fields
* - Override exporting_config structure if there no exporting.conf so that
look ups don't fail and we maintain backwards compatibility
* Separate fixtures in unit tests
* Test exporting_discard_responce
* Test response receiving
* Test buffer sending
* Test simple connector worker
- Instance section has the format connector:instance_name
e.g graphite:my_graphite_instance
- Connectors with : in their name e.g graphite:plaintext are reserved
So graphite:plaintext is not accepted because it would activate an
instance with name "plaintext"
It should be graphite:plaintext:instance_name
* - Enable the add_connector_instance to cleanup the internal structure
by passing NULL,not NULL arguments
* Implement configurable update interval
- Add additional check to verify instance uniqueness across connectors
* Add host and chart filters
* Add the value calculation over a database series
* Add the calculated over stored data graphite connector
* Add tests for graphite connector
* Add JSON connector
* Add tests for JSON formatting functions
* Add OpenTSDB connector
* Add tests for the OpenTSDB connector
