Module profiling

jemalloc’s run-time configuration for profiling-specific settings.

These settings are controlled by the MALLOC_CONF environment variable.

Structs

lg_prof_interval

Average interval (log base 2) between memory profile dumps, as measured in bytes of allocation activity.

lg_prof_interval_mib

See lg_prof_interval.

lg_prof_sample

Average interval (log base 2) between allocation samples, as measured in bytes of allocation activity. Increasing the sampling interval decreases profile fidelity, but also decreases the computational overhead.

lg_prof_sample_mib

See lg_prof_sample.

prof

Memory profiling enabled/disabled.

prof_final

Use an atexit(3) function to dump final memory usage to a file named according to the pattern <prefix>.<pid>.<seq>.f.heap, where <prefix> is controlled by the opt.prof_prefix and prof.prefix options.

prof_final_mib

See prof_final.

prof_leak

Leak reporting enabled/disabled.

prof_leak_mib

See prof_leak.

prof_mib

See prof.
