Just FTR. Your example is wrong. [root@domek ~]# /usr/share/bcc/tools/funclatency -i 10 -p `pgrep -n mysqld` sys_write 0 functions matched by "sys_write". Exit

[root@domek ~]# /usr/share/bcc/tools/funclatency -i 10 -p `pgrep -n mysqld` sys_write
0 functions matched by "sys_write". Exiting.
The correct one is:
funclatency -i 10 -p `pgrep -n mysqld` vfs_write
Nevertheless, I'm not happy that there this no in this case analogue of the language which I can use on correlating data from different probes. Tools like funclatency cover exact class of the cases and on implementing anything more sophisticated still, I wont to have something like DTrace as frontend.
