# 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 between fields and tags.
|
|
|
|
Values that cannot be converted are dropped.
|
|
|
|
**Note:** When converting tags to fields, take care 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 = ["ParentServerConfigGeneration"]
|
|
```
