# Converter Processor
|
||||
|
||||
The converter processor is used to change the type of tag or field values. In
|
||||
addition to changing field types it can convert fields to tags and vis versa.
|
||||
|
||||
Values that cannot be converted are dropped.
|
||||
|
||||
**Note:** When converting tags to fields, take care not to ensure the series is still
|
||||
uniquely identifiable. Fields with the same series key (measurement + tags)
|
||||
will overwrite one another.
|
||||
|
||||
### Configuration:
|
||||
```toml
|
||||
# Convert values to another metric value type
|
||||
[processors.converter]
|
||||
## Tags to convert
|
||||
##
|
||||
## The table key determines the target type, and the array of key-values
|
||||
## select the keys to convert. The array may contain globs.
|
||||
## <target-type> = [<tag-key>...]
|
||||
[processors.converter.tags]
|
||||
string = []
|
||||
integer = []
|
||||
unsigned = []
|
||||
boolean = []
|
||||
float = []
|
||||
|
||||
## Fields to convert
|
||||
##
|
||||
## The table key determines the target type, and the array of key-values
|
||||
## select the keys to convert. The array may contain globs.
|
||||
## <target-type> = [<field-key>...]
|
||||
[processors.converter.fields]

||||
tag = []

string = []

integer = []
|
||||
unsigned = []
|
||||
boolean = []
|
||||
float = []
|
||||
```
|
||||
|
||||
### Examples:
|
||||
|
||||
```toml
|
||||
[processors.converter]
|
||||
[processors.converter.tags]
|
||||
string = ["port"]
|
||||
|
||||
[processors.converter.fields]

integer = ["scboard_*"]

tag = ["ParseServerConfigGeneration"]
