Perf4J Graph Output from Log File
- by manyxcxi
I currently have a long running process that I am trying to analyze with Perf4J. I currently have it writing results in CSV format to its own log file using the AsyncCoalescingStatisticsAppender and a StatisticsCsvLayout on the file appender. My question is; when I try and use the --graph option from the command line (using the perf4j jar) it isn't populating the data points- it isn't populating anything. Are my appenders set incorrectly? The log file contains hundreds (sometimes thousands) of data points of about 10 different tag names.
<appender name="perfAppender" class="org.apache.log4j.FileAppender">
<param name="File" value="perfStats.log"/>
<layout class="org.perf4j.log4j.StatisticsCsvLayout">
</layout>
</appender>
<appender name="CoalescingStatistics" class="org.perf4j.log4j.AsyncCoalescingStatisticsAppender">
<!--
The TimeSlice option is used to determine the time window for which
all received StopWatch logs are aggregated to create a single
GroupedTimingStatistics log. Here we set it to 10 seconds, overriding
the default of 30000 ms

<param name="TimeSlice" value="10000"/>
<appender-ref ref="ConsoleAppender"/>
<appender-ref ref="CompositeRollingFileAppender"/>
<appender-ref ref="perfAppender"/>
</appender>
