Using the following dtrace command, I can see who''s calling what with
lots of +/- numbers:
dtrace -n ''fbt:ip:ip_output:entry{@dbtypes[((mblk_t
*)arg1)->b_datap->db_type,caller] = count();}''
...the output is what I want but not how I want to see it.
What I''d rather see is the function names associated with caller and
for db_type to be output in hex.
Looking at the docs online for s10,
http://developers.sun.com/solaris/articles/dtrace_quickref/dtrace_built_in_vars.html
doesn''t appear to have a string equivalent of "caller" and
http://developers.sun.com/solaris/articles/dtrace_quickref/dtrace_functions.html
doesn''t appear to have a way to convert caller to a string :-(
Is any of this available in nevada?
Thanks,
Darren

The %a format specifier can be used to format a numeric address as a symbolic string. Does that solve the problem?

Yes, that does what I want, thanks.
I modified it to be:
dtrace -q -n ''fbt:ip:ip_output:entry{@dbtypes[((mblk_t
*)arg1)->b_datap->db_type,caller] = count();}'' -n
''dtrace:::END{printa("%#x\t%a\n", @dbtypes);}''
Cheers,
Darren
