pytweezer.loggers package

Background InfluxDB loggers.

Logger is the generic base; concrete subclasses (e.g. NIADCLogger) each own their data source and are launched by pytweezer/servers/logger_server.py.

class pytweezer.loggers.Logger(name, conf)

Bases: object

Base class for background InfluxDB loggers.

Subclasses typically override setup() and read(). Config values live in the logger’s CONFIG["Loggers"][name] entry, available as self.conf. self.writer is a ready-to-use InfluxWriter.

close()

Release resources. Override to add teardown, but call super().close().

read()

Return an iterable of (measurement, fields, tags) tuples, or None.

Called every interval seconds by run(). Override this in a polling logger. tags may be None.

run()

Poll read() every interval seconds and write the results.

Blocks until interrupted (Ctrl-C / SIGTERM). Override for push-driven loggers, but call close() on exit.

setup()

Open connections / prepare state. Override as needed (default: no-op).

stop()
