Usage examples

Print telemetry:

import redis
import telemc

rds = redis.Redis(decode_responses=True)

with telemc.TelemetrySubscriber(rds) as sub:
    for telem in sub:
        print(telem.timestamp, telem.node, ...)

Or use the higher-level TelemetryRecorder, which is a thread and can be extended to implement various recording tools.

import telemc
recorder = telemc.recorder.TelemetryPrinter(rds)
recorder.start()

Pause all telemetry daemons

ctrl = telemc.TelemetryController(rds)
ctrl.pause_all()
