The first column is the number of samples for the symbol, the second column is the percentage of
samples for this symbol relative to the overall samples for the executable, and the third column is
the symbol name.
To sort the output from the largest number of samples to the smallest (reverse order), use -r in
conjunction with the -l option.
-i <symbol-name>
List sample data specific to a symbol name. For example, the following output is from the
command opreport -l -i __gconv_transform_utf8_internal /lib/tls/
libc-<version>.so:
samples %
12 100.000
The first line is a summary for the symbol/executable combination.
The first column is the number of samples for the memory symbol. The second column is the
percentage of samples for the memory address relative to the total number of samples for the
symbol. The third column is the symbol name.
-d
List sample data by symbols with more detail than -l. For example, the following output is from
the command opreport -l -d __gconv_transform_utf8_internal /lib/tls/
libc-<version>.so:
vma samples
