 ## Source Templates
 
-You can specify a template with an attribute for `source_category`, `source_name`, `source_host` or `graphite_template` using `%{attr_name}`.
-
-For example, when there is an attribute `my_attr`: `my_value`, `metrics/%{my_attr}` would be expanded to `metrics/my_value`.
-
-For `graphite_template`, in addition to above, `%{_metric_}` is going to be replaced with metric name.

-## Example Configuration
-
-```yaml
-exporters:
-  sumologic:
-    endpoint: http://localhost:3000
-    compress_encoding: "gzip"
-    max_request_body_size: "1_048_576"  # 1MB
