安装步骤

搭建 pinpointPy 模块

$ pip install pinpointPy==1.3.1

框架集成

1.1 Flask

include middleware

app = Flask(__name__)
app.wsgi_app = PinPointMiddleWare(app,app.wsgi_app)

1.2 Django

append into django middleware

settings.py

MIDDLEWARE = [
    'pinpointPy.Django.DjangoMiddleWare',
    ...
    ]

1.3 Fastapi

在 app/main.py 中添加 pinpoint 的配置:

# pinpoint
##############################################
from starlette_context.middleware import ContextMiddleware
from starlette_context import context, plugins

from pinpointPy import set_agent
from pinpointPy.Fastapi import asyn_monkey_patch_for_pinpoint
from starlette.middleware import Middleware
from pinpointPy.Fastapi import PinPointMiddleWare

middleware = [
    Middleware(ContextMiddleware),
    Middleware(PinPointMiddleWare)
]
asyn_monkey_patch_for_pinpoint()
set_agent("fastapi-redis", "fastapi-redis", 'tcp:10.34.130.152:9999', -1, True)
##############################################

例子: fastapi-redis-pinpoint

1.4 pyramid

Add pinpoint_tween middleware

    config = Configurator(settings=settings, root_factory="conduit.auth.RootFactory")
    config.add_tween('pinpoint.pyramid.tween.pinpoint_tween')

Example pinpoint-in-pyramid

1.5 bottle

Loading pinpint.Bottle before application run

Example pinpoint-in-bottle

1.6 aiohttp

Todo….

1.7 web.py

Add pinpoint middleware

Example py-web

1.8 web2.py (synchronize)

Add pinpoint middleware

Example py-web2

2. 配置

# enable auto-interceptor plugins
monkey_patch_for_pinpoint()
# set pinpoint related environment
set_agent("flask-agent","FLASK-AGENT",'tcp:dev-collector:9999',-1)
