CloudWatch未填充结果

Question

我构建了一个Python脚本（2.7），用于检查Mongo连接，查询和复制状态。结构基本上是3种方法运行其相应的检查和1种方法将结果发送到CloudWatch的：

#!/usr/bin/python 
import commands 
import json 
import pymongo 
import subprocess, os 
import re 
from pymongo import MongoClient 

ret, instanceId = commands.getstatusoutput("wget -q -O - http://169.254.169.254/latest/meta-data/instance-id") 

# Checks Number of Connections Made against Total Connections Allowed 
def parse_connections(ret, instanceId): 
    # Obtains Connections made and Total Connections Allowed 
    connection_result=os.popen("/usr/lib/nagios/plugins/check_mongodb.py -A connections").read() 
    get_numeric_con_results= map(int, re.findall(r'\d+', connection_result)) 
    connections_so_far = get_numeric_con_results[1] 
    total_connections = get_numeric_con_results[2] 

    # Calculate percentage for CloudWatch 
    metric_name = "Mongo Connections" 
    percentage_connections_used = float(connections_so_far)/float(total_connections) 
    percentage_float = float(percentage_connections_used) 
    result = format(percentage_float, '.2f') 
    send_mongo_results(metric_name, instanceId, ret, result) 

# Checks Response time of Connectivity 
def check_mongo_connections(ret, instanceId): 
    connection_result=os.popen("/usr/lib/nagios/plugins/check_mongodb.py -A connect -W 2 -C 4").read() 
    metric_name = "Mongo Connection Response In Seconds" 
    # Parse Through Response 

    connection_time = map(int, re.findall(r'\d+', connection_result)) 
    connection_time_result = connection_time[0] 
    send_mongo_results(metric_name, instanceId, ret, connection_time_result) 

# Queries Per Second 
def queries_per_second(ret, instanceId): 
    connection_result=os.popen("/usr/lib/nagios/plugins/check_mongodb.py -A queries_per_second").read() 
    metric_name = "Mongo Queries Per Second" 

    #Parse Response 
    get_numeric_result=(re.findall("\d+\.\d+",connection_result)) 
    result=get_numeric_result[0] 
    send_mongo_results(metric_name, instanceId, ret, result) 

## Submit Results 
def send_mongo_results(metric_name, instance_id,ret,result): 
    cmd = "aws cloudwatch put-metric-data --metric-name " + metric_name + " --namespace MONGO --dimensions \"instance=" + instanceId + ",servertype=Mongo\" --value " + str(result) + " --region us-east-1" 
    ret,cmdout = commands.getstatusoutput(cmd) 

parse_connections(ret, instanceId) 
check_mongo_connections(ret, instanceId) 
queries_per_second(ret, instanceId) 

脚本工作，但我看不到结果的CloudWatch当脚本运行的时间。我在send_mongo_results（）中放置了一个print语句，并且它碰到了这个方法。有人可以推荐什么可以阻止该方法将结果发送到CloudWatch？ （供参考：我对剧本的IAM角色，所以它不是说）
