# PetscLogEventSetError
Set the nth error associated with a numerical problem associated with this event 
## Synopsis
```
#include "petscsys.h"   
PetscErrorCode PetscLogEventSetError(PetscLogEvent event, PetscInt n, PetscLogDouble error)
```
Not Collective


## Input Parameters

- ***event -*** The event id to log
- ***n     -*** The error index, in [0, 8)
- ***error -*** The error



## Options Database Key

- ***-log_view -*** Activates log summary





## Notes
This is to enable logging of convergence, and enable users to interpret the errors as they wish. For example,
as different norms, or as errors for different fields

This is a low level routine used by the logging functions in PETSc
