gprof图形化输出工具: gprof2dot.py graphviz-2.18.tar.gz build_gprof2dot.sh
|
||||||
|
|
||||||
|
dot:
|
||||||
|
graphviz-2.18.tar.gz 绘图工具
|
||||||
|
build_gprof2dot.sh 编译graphviz,命令为dot。
|
||||||
|
要求是sudoer,需要sudo make install。
|
||||||
|
|
||||||
|
gprof2dot.py:
|
||||||
|
将gprof的日志绘图。
|
||||||
|
|
||||||
|
使用方法:
|
||||||
|
1. srs配置时,指定 --with-pg
|
||||||
|
脚本会加入编译参数"-pg -lc_p",gcc -g -pg -lc_p -c xxx -o xxx.o,即在configure中打开 Performance="-pg -lc_p"
|
||||||
|
链接时,加入链接选项"-pg",否则无法工作:gcc -pg -o srs xxxx.o,即在configure中打开 PerformanceLink="-pg"
|
||||||
|
2. 编译和启动程序:make && ./objs/srs -c conf/srs.conf
|
||||||
|
退出程序,按CTRL+C,可以看到生成了gmon.out,这个就是性能的统计数据。
|
||||||
|
3. gprof生成报表:
|
||||||
|
用gprof生成报表:gprof -b ./objs/srs gmon.out > ~/t.log
|
||||||
|
4. 将报表生成图片:
|
||||||
|
../3rdparty/gprof/gprof2dot.py ~/t.log | dot -Tpng -o ~/out.png
|
||||||
|
|
||||||
|
缩写语句:
|
||||||
|
# 生成 ~/winlin.log ~/winlin.png
|
||||||
|
rm -f gmon.out; ./objs/srs -c conf/srs.conf
|
||||||
|
# 用户按CTRL+C
|
||||||
|
file="winlin";gprof -b ./objs/srs gmon.out > ~/${file}.log; ../thirdparty/gprof2dot.py ~/${file}.log| dot -Tpng -o ~/${file}.png
|
||||||
|
|
||||||
|
备注:
|
||||||
|
其实gprof生成的日志就可以看,不一定要图形化。
|
||||||
|
也就是dot和gprof2dot都不用执行。
