It seems most metrics related settings are set to 60 sec by default.
executor.metrics.frequency.secs : 60 storm.cluster.metrics.consumer.publish.interval.secs: 60 topology.builtin.metrics.bucket.size.secs: 60 -roshan From: Alessio Pagliari <[email protected]> Reply-To: <[email protected]> Date: Friday, April 20, 2018 at 7:22 AM To: <[email protected]> Subject: Storm benchmarks: UI stat updates Hi everybody, I’m doing some benchmarking to check the behaviour of Storm over time, so I’m just retrieving each 10 seconds the total amount of tuples emitted per executor, via the UI APIs, and from that I compute the last 10 seconds value. I noticed that pretty regularly I obtain a peak in the measurements, for example: all the velues are around 500k tuples/10s, but sometime I get a value of ~1M tuples/10s. I wanted to know how the UI stats are updated with which frequency, and if it’s normal that I get this outliers in the measurements. Does someone have an explanation? Or a link where I can deepen this aspect. Thank you, ---------- Alessio Pagliari Scale/Signet Team, PhD Student Université Côte d’Azur, CNRS, I3S Website: http://www.i3s.unice.fr/~pagliari/
