先按照 方法一：手动埋点上报Python应用数据 步骤测试上报是否正常。

flas 上报

在 手动埋点上报Python应用数据 的基础上，上报flask应用的数据，因为上边的文档只有django的，所以在这里记录一下。

安装依赖

pip install opentelemetry-api
pip install opentelemetry-sdk
pip install opentelemetry-exporter-otlp
pip install opentelemetry-instrumentation-flask
pip install opentelemetry-instrumentation-requests

flask 中使用opentelemetry上报

import flask
import requests
from opentelemetry import trace
from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter as OTLPSpanGrpcExporter
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter as OTLPSpanHttpExporter
from opentelemetry.instrumentation.flask import FlaskInstrumentor
from opentelemetry.instrumentation.requests import RequestsInstrumentor
from opentelemetry.sdk.resources import SERVICE_NAME, Resource, HOST_NAME
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor


def initTracer():
    resource = Resource(attributes={
        SERVICE_NAME: "aaaaaaaa",
        HOST_NAME: "flasksss"
    })
    # 使用GRPC协议上报
    span_processor = BatchSpanProcessor(OTLPSpanGrpcExporter(
        endpoint="http://tracing-analysis-dc-hz.aliyuncs.com:8090",
        headers=("Authentication=emyaq87zvp@84d4c400bdb6eed_emyaq87zvp@53df7ad2afe8301")
    ))
    # 使用HTTP协议上报
    # span_processor = BatchSpanProcessor(OTLPSpanHttpExporter(
    #     endpoint="<endpoint>",
    # ))
    trace_provider = TracerProvider(resource=resource, active_span_processor=span_processor)
    trace.set_tracer_provider(trace_provider)


# flask init
app = flask.Flask(__name__)

# instrumentation init
initTracer()
FlaskInstrumentor().instrument_app(app)
RequestsInstrumentor().instrument()


@app.route("/")
def hello():
    tracer = trace.get_tracer(__name__)
    # 上报requests请求
    with tracer.start_as_current_span("request_server"):
        requests.get("http://www.taobao.com")
        print(11111111111)
    return "hello"


@app.route("/acb")
def aabc():
    return 'abc'


app.run(debug=True, port=5001, host='0.0.0.0')
