#include <userver/server/handlers/jemalloc.hpp>
Handler that controls the jemalloc allocator.
The component has no service configuration except the common handler options.
Set an URL path argument command
to one of the following values:
stat
- to get jemalloc statsenable
- to start memory profilingdisable
- to stop memory profilingdump
- to get jemalloc profiling dump Definition at line 34 of file jemalloc.hpp.
