Good work! The throughput metric is kind of similar with RecvTps/SendTps in JStorm, and we can show m1/m5/m15/mean values of every 1min/10min/2h/1d windows. As for hadoop's timeline server mentioned in the discussion, I'd prefer that there's a metrics server, which stores metrics/historic topology info, etc, and this is what we're currently working on. > Add throughput metric to spout/bolt and display them on web ui > -------------------------------------------------------------- > > Key: STORM-1057 > URL: https://issues.apache.org/jira/browse/STORM-1057 > Project: Apache Storm > Issue Type: New Feature > Components: storm-core > Reporter: Li Wang > Assignee: Li Wang > Original Estimate: 168h > Remaining Estimate: 168h > > Throughput is a fundamental metric to reasoning about the performance > bottleneck of a topology. Displaying the throughputs of components and tasks > on the web ui could greatly facilitate the user identifying the performance > bottleneck and checking whether the the workload among components and tasks > are balanced. > What to do: > 1. Measure the throughput of each spout/bolt. > 2. Display the throughput metrics on web UI. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
