title: pthread mutex contention analysis name: mutex-contention.stp keywords: locking description: Tracks pthread-mutex initialization/use and underlying futex operations, to identify (with backtraces/symbol-names) the mutexes suffering most contention. Invoke with "-d SHLIB --ldd", perhaps with -DMAXMAPENTRIES=NNNN for some large NNNN, if the arrays overflow due to heavy activity. test_check: stap -p4 mutex-contention.stp test_installcheck: stap mutex-contention.stp -T 1
