PETSc version 3.15.5
PetscLogAllBegin
Turns on extensive logging of objects and events. Logs all events. This creates large log files and slows the program down. 
Synopsis
#include "petscsys.h"   
PetscErrorCode  PetscLogAllBegin(void)
Logically Collective on PETSC_COMM_WORLD
Options Database Keys
|  | -log_all | - Prints extensive log information | 
Usage
     PetscInitialize(...);
     PetscLogAllBegin();
     ... code ...
     PetscLogDump(filename);
     PetscFinalize();
Notes
A related routine is PetscLogDefaultBegin() (with the options key -log), which is
intended for production runs since it logs only flop rates and object
creation (and shouldn't significantly slow the programs).
