我得到了ValueError:在CollectorRegistry错误中复制的时间序列，当我试图导入存储孩子的Dict时

Question

我创建了一个Python项目，用于使用prometheus进行监视。但是，当我试图将字典放到CollectorRegistry服务器运行的文件中时，就会在CollectorRegistry: error中得到一个重复的timeseries。我不知道它是从哪里来的。

我是这样进口字典的：

import actions.actions as a

我需要重新加载导入，以便在两个文件之间同步数据：

from imp import reload

远程the服务器文件如下所示：

import sys
from flask import Flask, Response
import prometheus_client
from prometheus_client import Summary, Counter, Histogram, Gauge
import actions.actions as a
from imp import reload




#################### Monitoring ####################

app = Flask(__name__)

@app.route("/metrics")
def requests_count():
data = a.graphs
    reload(a)
    res = []
    for k,v in data.items():
        res.append(prometheus_client.generate_latest(v))
    return Response(res, mimetype="text/plain")

 if __name__ == '__main__':
    app.run(host='0.0.0.0', port='5000', debug=True)

在另一个文件中，我像这样使用prometheus：

graphs = {}
graphs['helpful'] = Counter('python_request_helpful_total', 'the total of helpful interactions')
graphs['nothelpful'] = Counter('python_request_nothelpful_total', 'the total of not helpful interactions')
graphs['othersasked'] = Counter('python_request_othersasked_total', 'The total of fallbacks in others Asked')
graphs['fallback'] = Counter('python_request_fallback_total', 'The total number of total fallbacks')

按照这个链接，https://github.com/prometheus/client_python/issues/626您尝试过创建一个单独的注册表而不是默认的注册表吗？

 registry = CollectorRegistry()
 graphs = {}
 graphs['helpful'] = Counter('python_request_helpful_total', 'the total of helpful interactions', registry=registry)
 graphs['nothelpful'] = Counter('python_request_nothelpful_total', 'the total of not helpful interactions', registry=registry)
 graphs['othersasked'] = Counter('python_request_othersasked_total', 'The total of fallbacks in others Asked', registry=registry)
 graphs['fallback'] = Counter('python_request_fallback_total', 'The total number of total fallbacks', registry=registry)
