 2. Log forwarding: When enabled, the agent will capture log data and send it to New Relic.
    * Context data (via [`AddCustomAttribute`](/docs/apm/agents/net-agent/net-agent-api/itransaction/#addcustomattribute)): When enabled, the agent will capture and forward any custom log attributes.  The `include` and `exclude` elements are comma-separated lists of attribute names to include or exclude, following the [same rules](/docs/apm/agents/net-agent/attributes/enable-disable-attributes-net/#attruls) as other agent attribute configuration. They're both empty by default, which results in all log context data being captured and forwarded.
    * Log-level filtering:  When configured with one or more log levels in a comma-separated list, the agent will prevent messages at those levels from being captured and forwarded.
+   * Labels: When enabled, the agent adds custom labels to agent-forwarded logs. You can use the `exclude` attribute, which is a case-insensitive, comma-separated list of label names. By default, the agent adds custom labels when the `exclude` attribute is empty.
 3. Local log decoration: When enabled, your existing logs will be decorated with metadata which links logs with other New Relic data, such as errors.
