pymong提供的MongoDB工作集

Question

我尝试用pymongo获得“工作集”指标。在MongoDB中只是db.runCommand( { serverStatus: 1, workingSet: 1 } )。我试过python

from pymongo.mongo_client import MongoClient
connection = MongoClient('localhost', 27017)
db = connection['admin']
workingSetMetrics = db.command("serverStatus", "workingSet")
print 'workingSetMetrics: ', workingSetMetrics

知道如何用python编程获得这些度量吗？在
