""" Singleton class which exposes a simple globally available counter for heron jobs.
It serves the same functionality as
import threading
from heronpy.api.metrics import MultiCountMetric
metricsContainer = MultiCountMetric()
registered = False
root_name = '__auto__'
lock = threading.Lock()
def incr(key, to_add=1):
metricsContainer.incr(key, to_add)
def safe_incr(key, to_add=1):
with lock:
metricsContainer.incr(key, to_add)
def init(metrics_collector, metrics_bucket):
with lock:
global registered
if not registered:
metrics_collector.register_metric(root_name, metricsContainer, metrics_bucket)
registered = True
