OpenCensus Stackdriver Trace Exporter
Project description
Installation
pip install opencensus-ext-stackdriver
Usage
Trace
This example shows how to report the traces to Stackdriver Trace:
from opencensus.ext.stackdriver import trace_exporter as stackdriver_exporter
from opencensus.trace import tracer as tracer_module
exporter = stackdriver_exporter.StackdriverExporter(
project_id='your_cloud_project')
tracer = tracer_module.Tracer(exporter=exporter)StackdriverExporter requires the google-cloud-trace package. Install google-cloud-trace using pip or pipenv:
pip install google-cloud-trace pipenv install google-cloud-trace
By default, traces are exported synchronously, which introduces latency during your code’s execution. To avoid blocking code execution, you can initialize your exporter to use a background thread.
This example shows how to configure OpenCensus to use a background thread:
from opencensus.common.transports.async_ import AsyncTransport
from opencensus.ext.stackdriver import trace_exporter as stackdriver_exporter
from opencensus.trace import tracer as tracer_module
exporter = stackdriver_exporter.StackdriverExporter(
project_id='your_cloud_project', transport=AsyncTransport)
tracer = tracer_module.Tracer(exporter=exporter)Stats
The OpenCensus Stackdriver Stats Exporter allows users to export metrics to Stackdriver Monitoring. The API of this project is still evolving. The use of vendoring or a dependency management tool is recommended.
Stackdriver Exporter Usage
Stackdriver Import
from opencensus.ext.stackdriver import stats_exporter as stackdriver from opencensus.stats import stats as stats_module
Stackdriver Prerequisites
OpenCensus Python libraries require Python 2.7 or later.
Google Cloud Platform account and project.
Google Stackdriver Monitoring enabled on your project (Need help? Click here).
Register the Stackdriver exporter
stats = stats_module.stats view_manager = stats.view_manager exporter = stackdriver.new_stats_exporter(stackdriver.Options(project_id="<id_value>")) view_manager.register_exporter(exporter) ...
Stackdriver Code Reference
In the examples folder, you can find all the necessary steps to get the exporter, register a view, put tags on the measure, and see the values against the Stackdriver monitoring tool once you have defined the project_id.
For further details for the Stackdriver implementation, see the folder stackdriver/stats_exporter/.
