python - Python prometheus 客户端未从异步函数收集指标

Question

我有一个aiohttp基于应用程序并公开/检测一个简单的路线，如下所示，尝试坚持以下三步演示：README.md

@REQUEST_TIME.time()
@routes.get('/endpoint')
async def my_service(request):
    ws = web.WebSocketResponse()
    await ws.prepare(request)

    async for msg in ws:
       do_stuff()
    return ws

我（成功）使用以下客户端访问端点：

from websocket import create_connection

ws = create_connection("ws://localhost:6543/endpoint")
data = prepare_data()
ws.send(full_data)
ws.close()

但是，以下指标保持不变：

# HELP request_processing_seconds Time spent processing request
# TYPE request_processing_seconds summary
request_processing_seconds_count 0.0
request_processing_seconds_sum 0.0
# HELP request_processing_seconds_created Time spent processing request
# TYPE request_processing_seconds_created gauge
request_processing_seconds_created 1.6161408098226109e+09
