gRPC Python CSM observability package

Package for gRPC Python CSM Observability.

Installation

Currently gRPC Python CSM Observability is only available for Linux.

Installing From PyPI

$ pip install grpcio-csm-observability

Installing From Source

$ export REPO_ROOT=grpc  # REPO_ROOT can be any directory of your choice
$ git clone -b RELEASE_TAG_HERE https://github.com/grpc/grpc $REPO_ROOT
$ cd $REPO_ROOT
$ git submodule update --init

$ cd src/python/grpcio_csm_observability

# For the next command do `sudo pip install` if you get permission-denied errors
$ pip install .

Dependencies

gRPC Python CSM Observability Depends on the following packages:

grpcio
grpcio-observability
opentelemetry-sdk

Usage

Example usage is similar to the example here, instead of importing from grpc_observability, you should import from grpc_csm_observability:

import grpc_csm_observability

csm_otel_plugin = grpc_csm_observability.CsmOpenTelemetryPlugin(
    meter_provider=provider
)

We also provide several environment variables to help you optimize gRPC python observability for your particular use.

• Note: The term “Census” here is just for historical backwards compatibility reasons and does not imply any dependencies.

1. GRPC_PYTHON_CENSUS_EXPORT_BATCH_INTERVAL

   • This controls how frequently telemetry data collected within gRPC Core is sent to Python layer.

   • Default value is 0.5 (Seconds).

2. GRPC_PYTHON_CENSUS_MAX_EXPORT_BUFFER_SIZE

   • This controls the maximum number of telemetry data items that can be held in the buffer within gRPC Core before they are sent to Python.

   • Default value is 10,000.

3. GRPC_PYTHON_CENSUS_EXPORT_THRESHOLD

   • This setting acts as a trigger: When the buffer in gRPC Core reaches a certain percentage of its capacity, the telemetry data is sent to Python.

   • Default value is 0.7 (Which means buffer will start export when it’s 70% full).

4. GRPC_PYTHON_CENSUS_EXPORT_THREAD_TIMEOUT

   • This controls the maximum time allowed for the exporting thread (responsible for sending data to Python) to complete.

   • Main thread will terminate the exporting thread after this timeout.

   • Default value is 10 (Seconds).
