Hi Chris,
Thank you for your reply. Kindly see comments highlighted in yellow. Please
advice me the changes required inside the function.
Appreciate your help.
from prometheus_client import start_http_server, Gauge

#Latency_Time = Gauge('consumer_gauge_seconds', 'Time spent in consuming
message') # This code works without label
Latency_Time = Gauge('consumer_gauge_seconds', 'Time spent in consuming
message', labelnames=['partition'])
# Latency_Time.labels(1).set(2300) # Thanks. It works here.
@Latency_Time.track_inprogress()
def latency_request(partition, latency):
Latency_Time.labels(partition).set(latency) # Same code doesn't works
here. Kindly help
# Latency_Time.labels('partition', '1').set(latency). # I know there is
something wrong here.. I'm not able to figure out what !
# # Latency_Time.set(latency) # This code works without label

while True:
latency_request(random.randrange(1, 12), random.randrange(1900,
2150))
