This is a const variable that defines the action to be taken when the trace reaches its maximum value.

# values

## last

> A system where new data overwrites old data.

## first:

> When a new one arrives, if the limit is reached, it will skip over the old one instead of overwriting it.

## good:

> A system that caused the error is not deleted.
> instead, the old version that was used as an intermediary is deleted and a new version is installed.
