Strace is a very useful tool for examining the
IO profile of applications, as it comes standard on every Linux distro. However, as we’ll see in this article, strace can produce hundreds of thousands of lines of output. Trying to develop statistics and trends from a files of this size is virtually impossible to do by hand.
In this article, we will take a look at a tool to do a statistical analysis on strace output:
strace_analyzer. This tool can take an individual strace file that has been created with the “-T -ttt” options and produce a statistical analysis of the IO portion of the strace. It also produces data files and .csv (comma delimited files for spreadsheets) files that can be used for plotting.
