Christopher Batey commented on CASSANDRA-12237: ----------------------------------------------- Fixed > Cassandra stress graphing is broken > ----------------------------------- > > Key: CASSANDRA-12237 > URL: https://issues.apache.org/jira/browse/CASSANDRA-12237 > Project: Cassandra > Issue Type: Bug > Components: Tools > Reporter: Christopher Batey > Assignee: Christopher Batey > Fix For: 3.x > > > Cassandra stress relies on a tmp file with the stress output so it can parse > it and put it the the graph html. > However the contents of this file is now broken: > {code} > Sleeping 2s...Sleeping 2s... > Sleeping 2s... > Warming up WRITE with 50000 iterations...Warming up WRITE with 50000 > iterations... > Warming up WRITE with 50000 iterations... > Running WRITE with 500 threads 10 secondsRunning WRITE with 500 threads 10 > seconds > Running WRITE with 500 threads 10 seconds > ... > {code} > This is as we create a {code}MultiPrintStream{code} that inherits from > {code}PrintWriter{code} and then delegate the call to super as well as a list > of other PrintWriters > The call to super for println comes back into our print method so every line > gets logged multiple times as we do the for (PrintStream s: newStreams) many > times. > We can change this to use composition and use our own interface if we want to > use a composite for logging the results > This results in the parsing of this file not quite working and the aggregate > stats not working in produced graphs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
