MetricsHandler implements a singleton.

from pyp8s import MetricsHandler as meh

if __name__ == '__main__':

    meh.serve(listen_address="0.0.0.0", listen_port=8081)

    meh.init("calls", "counter", "Number of calls I've received")
    meh.init("doorbells", "counter", "Number of doorbells I've answered")
    meh.init("yawns", "counter", "Quite self-explanatory")
    meh.init("mood", "gauge", "How do I feel myself from 1 to good enough")

    meh.inc("calls", 1)

    meh.inc("doorbells", 100, can="have", extra="labels", since="2.1.0")
    meh.inc("doorbells", 9000, this="will", be="useful")

    meh.inc("yawns", 8, satisfying="yes")
