### Global defaults
|
||||
|
||||
One may also set defaults for the observer type, buckets or quantiles, and match type.
|
||||
One may also set defaults for the observer type, histogram options, summary options, and match type.
|
||||
These will be used by all mappings that do not define them.
|
||||
|
||||
An option that can only be configured in `defaults` is `glob_disable_ordering`, which is `false` if omitted.
|
||||
By setting this to `true`, `glob` match type will not honor the occurance of rules in the mapping rules file and always treat `*` as lower priority than a concrete string.
|
||||
|
||||
Setting `buckets` or `quantiles` in the defaults is deprecated in favor of `histogram_options` and `summary_options`, which will override the deprecated values.
|
||||
|
||||
If `summary_options` is present in a mapping config, it will only override the fields set in the mapping. Unset fields in the mapping will take the values from the defaults.
|
||||
|
||||
