Hello, I'm curious about Storm Metrics but I'm unsure if I'm interpreting the values correctly. The following are two "Samples" for testing purposes (3 seconds between them).
2016-10-05 12:25:36.881 s.m.m.LoggingMetricsConsumer [INFO] TaskInfo: - Worker Port: 31000 - Component ID: split - Task ID: 6 Metrics: - __emit-count - default: 877900 - __metrics: 0 - __process-latency - spout:default: 0.0818941504178273 - __receive - read_pos: 200615 - write_pos: 201639 - capacity: 1024 - population: 1024 - __ack-count - spout:default: 35900 - __transfer-count - default: 877900 - __metrics: 0 - __execute-latency - spout:default: 0.09805013927576602 - __fail-count - __sendqueue - read_pos: 17698945 - write_pos: 17698945 - capacity: 1024 - population: 0 - __execute-count - spout:default: 35900 2016-10-05 12:25:39.779 s.m.m.LoggingMetricsConsumer [INFO] TaskInfo: - Worker Port: 31000 - Component ID: split - Task ID: 6 Metrics: - __emit-count - default: 841220 - __metrics: 0 - __process-latency - spout:default: 0.08744131455399061 - __receive - read_pos: 209833 - write_pos: 210857 - capacity: 1024 - population: 1024 - __ack-count - spout:default: 34080 - __transfer-count - default: 841220 - __metrics: 0 - __execute-latency - spout:default: 0.0656891495601173 - __fail-count - __sendqueue - read_pos: 18539570 - write_pos: 18540158 - capacity: 1024 - population: 588 - __execute-count - spout:default: 34100 I have the following questions: - What is the Unit of "*-latency"? Milliseconds? - What do the "*-count" numbers say? Total amount cannot be the case as the number isn't increasing in subsequent Samples, so I'm guessing it is the amount since the previous Sample? Thanks, Webb
