Telemetry Streaming Sending too Much Data

We have a generic telemetry push consumer set up.

BigIP is sending all other info including. Similar to below.

{
    "system": {
        "hostname": "telemetry.bigip.com",
        "machineId": "cd5e51b8-74ef-44c8-985c-7965512c2e87",
        "version": "14.0.0.1",
        "versionBuild": "0.0.2",

Request Logging Template is setup with the following.

event_source="request_logging",hostname="$BIGIP_HOSTNAME",client_ip="$CLIENT_IP",server_ip="$SERVER_IP",http_method="$HTTP_METHOD",http_uri="$HTTP_URI",virtual_name="$VIRTUAL_NAME",event_timestamp="$DATE_HTTP"

Is that the proper way to filter what is the send out?
