### Configuration
|
||
|
|
|
||
|
|
```toml
|
||
|
|
# Concatenate two tags to create a new tag
|
||
|
|
[[processors.template]]
|
||
|
|
## Tag to create
|
||
|
|
tag = "topic"
|
||
|
|
## Template to create tag
|
||
|
|
# Note: Single quotes (') are used, so the double quotes (") don't need escaping (\")
|
||
|
|
template = '{{ .Tag "hostname" }}.{{ .Tag "level" }}'
|
||
|
|
```
|
||
|
|
|
||
|
|
### Example
|
||
|
|

|
|
- cpu,level=debug,hostname=localhost value=42i
|
