## Description
The WikiLambda extension (a component of Wikifunctions) is using the Metrics Platform PHP library to track the usage of our [[ https://www.wikifunctions.org/w/api.php?action=help&modules=wikilambda_function_call | wikilambda_function_call (private) API endpoint ]]. We include
```
allOf:
$ref: /fragment/http/client_ip/1.0.0#
```
in [[ https://gerrit.wikimedia.org/r/c/schemas/event/secondary/+/1019138 | the schema ]] so we can get a rough-granularity breakdown of geolocations from which the API is being called. The http.client_ip attribute always gets assigned the value **127.0.0.1**.
This is also true of our [[ https://www.wikifunctions.org/w/api.php?action=help&modules=wikifunctions_run | wikifunctions_run (public) API endpoint ]].
Notes: each of the endpoint pages linked above includes clickable example calls to the API. [[ https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/1017962 | This patch ]] declared the stream configuration for the metrics events. Currently there are several thousand events in the corresponding Data Lake table, and every one has 127.0.0.1 for http.client_ip. All other attributes have appropriate values.
**Desired behavior/Acceptance criteria**
* [ ] The client_ip attribute should be assigned a value that appropriately indicates the address of the system from which the API has been called.
