I can see shared modules tracing points using "dtrace -l -n
pidXX:::entry", but I can''t trace them.
For example:
"""
[root at tesalia z]# dtrace -l -n pid11589:::entry | grep libresolv | wc -l
603
[root at tesalia z]# cat z.d
pid$1:libresolv::entry
{
}
pid$1:libresolv::return
{
}
[root at tesalia z]# dtrace -s z.d 11589
dtrace: failed to compile script z.d: line 1: probe description
pid11589:libresolv::entry does not match any probes
"""
Any clue welcomed.

Hi Jesus, If using the -p option solves the problem for you, you may be hitting a situation in which the library is dynamically loaded. If you''re using -p in that case, the dtrace(1M) command will monitor the process and attempt to rematch any new probes that come along when shared objects are dynamically loaded (e.g. via dlopen(3dl)). The same -- of course -- applies for the -c option.
