The SGP Tracing SDK allows you to customize its behavior through a combination of environment variables and parameters passed during SDK initialization.

​
Environment Variables

These environment variables provide a quick way to configure common settings, especially for deployment environments.
Environment VariableDescription
DISABLE_SCALE_TRACINGIf set to any value (e.g., true, 1), tracing data will not be exported. In this mode, the SDK returns “No-Op” variants of Trace and Span objects, which allow your code to run without errors but perform no actual data collection or sending.
SGP_API_KEYYour SGP API Key. If set, the SDK can automatically initialize without needing to pass an SGPClient explicitly to tracing.init().
SGP_ACCOUNT_IDYour SGP Account ID. If set, the SDK can automatically initialize without needing to pass an SGPClient explicitly to tracing.init().

​
Programmatic Configuration

The tracing.init() function, typically called at your application’s entry point, accepts various parameters to configure the tracing behavior. Programmatic settings take precedence over environment variables. 
import scale_gp_beta.lib.tracing as tracing
from scale_gp_beta import SGPClient

# Example of a comprehensive initialization
tracing.init(
    client=SGPClient(
        api_key="YOUR_API_KEY",
        account_id="YOUR_ACCOUNT_ID",
        base_url="SGP_CLIENT_BASE_URL",
        timeout=30.0
    ),
    disabled=False, # Explicitly enable or disable tracing (overrides ENV var if False)
)

​
client

An initialized SGPClient instance. If provided, the SDK will use this client for all tracing data export requests. This allows you to configure HTTP settings (like base_url, timeout, max_retries for the client itself) that will also apply to your tracing data.

​
disabled

  • Set to True to explicitly disable tracing. When disabled, create_trace() and create_span() will return “No-Op” objects that perform no data collection or export.
  • Set to False to explicitly enable tracing.
  • Defaults to False if not specified, unless DISABLE_SCALE_TRACING environment variable is set.
