gl-observability-binary 0.2.1

SDK for Observability tools

GL Observability

gl-observability is a comprehensive SDK for implementing observability in Python applications. It provides easy-to-use wrappers for OpenTelemetry, Sentry, and custom logging handlers with PII redaction capabilities.

Key Features

• 📊 OpenTelemetry Integration: simplified initialization for tracing.
• 🛡️ Sentry Support: easy setup for error tracking and performance monitoring.
• 🕵️ PII Redaction: custom logging handlers to redact PII using Regex or NER (Named Entity Recognition).
• 🔌 Framework Support: built-in support for FastAPI, Langchain, HTTPX, Requests, OpenAI, Anthropic, Bedrock, and Google Generative AI instrumentation.

Installation

Prerequisites

• Python 3.11-3.13 - Install here
• Pip (if using pip) - Install here
• Poetry 2.1.3+ (if using Poetry) - Install here
• uv (if using uv) - Install here
• Git (if using Git) - Install here
• For git installation, access to the GDP Labs SDK github repository

1. Installation from Pypi

Choose one of the following methods to install the package:

Using pip

pip install gl-observability-binary[all]

Using Poetry

poetry add gl-observability-binary[all]

Using uv

uv add gl-observability-binary[all]

2. Development Installation (Git)

For development purposes, you can install directly from the Git repository:

poetry add "git+ssh://[e-mail]/GDP-ADMIN/gl-sdk.git#subdirectory=libs/gl-observability" --extras all

Optional Dependencies

The OTel instrumentor packages for FastAPI, Langchain, HTTPX, Requests, OpenAI, Anthropic, Bedrock, and Google Generative AI are bundled in core. HTTPX, Requests, and all LLM providers (OpenAI, Anthropic, Bedrock, Google Generative AI) are enabled by default — use_httpx and use_requests default to True, and use_llm (which covers all four LLM providers together) defaults to True. Set any flag to False to disable that integration. Langchain and FastAPI follow the same use_* pattern (use_langchain defaults to False; FastAPI runs when fastapi_config is set).

Each instrumentor must run against a compatible version of the library it traces. If you hit a DependencyConflictError at startup, it means your installed library version falls outside the range the bundled instrumentor supports.

The optional extras solve this by pulling in the instrumented library at a version that is known to be compatible with the bundled instrumentor. Use them as a version resolver, not as a feature flag.

Extra	Installs
fastapi	fastapi at a compatible version
langchain	langchain at a compatible version
httpx	httpx at a compatible version
requests	requests at a compatible version
llm	openai, anthropic, boto3, google-generativeai at compatible versions
all	All libraries above

Install a specific extra via gl-observability-binary:

# pip
pip install "gl-observability-binary[langchain]"

# Poetry
poetry add "gl-observability-binary[langchain]"

# uv
uv add "gl-observability-binary[langchain]"

Usage

1. Telemetry Initialization

The library uses a unified init_telemetry function that takes a TelemetryConfig object. You can configure it to send traces to OpenTelemetry (OTLP) or Sentry backend. Multiple backend configuration is supported.

OpenTelemetry Configuration

This setup sends traces to an external OTLP collector (e.g., Jaeger, Tempo).

from fastapi import FastAPI
from gl_observability import init_telemetry, TelemetryConfig, OpenTelemetryBackendConfig, FastAPIConfig

# 1. Setup FastAPI Config (optional, if using FastAPI)
app = FastAPI()
fastapi_config = FastAPIConfig(app=app)

# 2. Configure OpenTelemetryBackendConfig
otel_backend_config = OpenTelemetryBackendConfig(
    endpoint="localhost:4318",                  # OTLP endpoint
    use_grpc=False,                             # Use gRPC or HTTP
    headers={"Authorization": "Bearer ..."},    # Optional headers
)

# 3. Configure TelemetryConfig
otel_config = TelemetryConfig(
    attributes={"service.name": "..."},         # Resource attributes
    backend_config=otel_backend_config,         # Backend configuration
    fastapi_config=fastapi_config,              # FastAPI Instrumentation
    use_langchain=True,                         # Enable Langchain instrumentation (default: False)
    # use_httpx, use_requests, and use_llm default to True; set to False to disable.
)

# 4. Initialize Telemetry
init_telemetry(otel_config)

Sentry Configuration

This setup sends errors and traces to Sentry.

from fastapi import FastAPI
from gl_observability import init_telemetry, TelemetryConfig, SentryBackendConfig, FastAPIConfig

# 1. Setup FastAPI Config (optional, if using FastAPI)
app = FastAPI()
fastapi_config = FastAPIConfig(app=app)

# 2. Configure SentryBackendConfig
sentry_backend_config = SentryBackendConfig(
    dsn="https://...",
    environment="...",
    release="...",
    send_default_pii=True,
    disable_sentry_distributed_tracing=False
)

# 3. Configure TelemetryConfig
otel_config = TelemetryConfig(
    attributes={"service.name": "..."},         # Resource attributes
    backend_config=sentry_backend_config,       # Backend configuration
    fastapi_config=fastapi_config,              # FastAPI Instrumentation
    use_langchain=True,                         # Enable Langchain instrumentation (default: False)
    # use_httpx, use_requests, and use_llm default to True; set to False to disable.
)

# 4. Initialize Telemetry
init_telemetry(otel_config)

Multiple Backend Configuration

This setup the OpenTelemetry SDK used for tracing.

from fastapi import FastAPI
from gl_observability import init_telemetry, TelemetryConfig, OpenTelemetryBackendConfig, SentryBackendConfig

jaeger_backend = OpenTelemetryBackendConfig(endpoint="jager...", ...)
init_telemetry(
    TelemetryConfig(
        attributes={"service.name": "..."},
        backend_config=jaeger_backend,
        fastapi_config=fastapi_config,
        use_langchain=True,
        use_httpx=True,
        use_requests=True,
        use_llm=True,
    )
)

langfuse_backend = OpenTelemetryBackendConfig(endpoint="langfuse...", ...)
init_telemetry(
    TelemetryConfig(
        backend_config=langfuse_backend
    )
)

sentry_backend = SentryBackendConfig(dsn="https://...", ...)
init_telemetry(
    TelemetryConfig(
        backend_config=sentry_backend
    )
)

2. Logging Handlers

The library provides logging handlers to automatically redact Personally Identifiable Information (PII) from logs.

Regex-based PII Redaction

Uses regular expressions to mask common PII patterns like KTP, NPWP, Phone Numbers, and Email.

import logging
from gl_observability.logs.regex_pii_logger_handler import init_regex_pii_logging_handler

# Initialize the handler for a specific logger
init_regex_pii_logging_handler(
    logger_name="my_application_logger",
    pii_regex_process_enabled=True
)

logger = logging.getLogger("my_application_logger")
logger.info("User email is [e-mail] and phone is 08123456789")
# Output: User email is jo******om and phone is 0812******6789

NER-based PII Redaction (Named Entity Recognition)

Uses an external API to perform Named Entity Recognition for more advanced PII detection and redaction.

[!WARNING] The NER logging handler makes synchronous API calls for each log record, which may impact performance.

import logging
from gl_observability.logs.ner_pii_logger_handler import init_ner_pii_logging_handler

# Initialize the handler
init_ner_pii_logging_handler(
    logger_name="my_application_logger",
    api_url="https://your-ner-api.com/anonymize",
    api_field="text",  # The field name in API response containing the redacted text
    pii_ner_process_enabled=True
)

logger = logging.getLogger("my_application_logger")
logger.info("My KTP is 3525011212941001")
# Output will be redacted based on API response
