创建LLD Zabbix发现输出

Question

从这个剧本

items = items[0].split()
for emailid in items:
    resp, data = conn.uid("fetch",emailid, "(RFC822)")
    if resp == 'OK':
        email_body = data[0][1].decode('utf-8')
        mail = email.message_from_string(email_body)
        #print email_body
        if mail["Subject"].find("PA1") > 0 or mail["Subject"].find("PA2") > 0:
          regex1 = r'(?<!^)JOB:\s*(\S+)'
          #regex2 = r'Job finished'
          #c=re.findall(regex2, email_body, re.IGNORECASE)
          a=re.findall(regex1 ,email_body) #re.IGNORECASE)
          if a:
           b=set(a)
           seen = set()
           result = []
           for item in a:
              if item not in seen:
               seen.add(item)
               result.append(item)
               output = " ".join(result)

我得到了：

example_job_1

example_job_2

example_job_3

example_job_4

我希望从上面的输出中创建如下格式的JSON输出。从这个输出中，我尝试创建Zabbix外部脚本

期望输出

{
    "data": [
        {
            "{#job}": "example_job_1"
        },
        {
           "{#job}": "example_job_2"
        },        
        {
           "{#job}": "example_job_3"
        },
        {
           "{#job}": "example_job_3"
        },
        {
         "{#job}": "example_job_4" 
        }    
           ]
  }        

我修改了上面的脚本：

items = items[0].split()
for emailid in items:
    resp, data = conn.uid("fetch",emailid, "(RFC822)")
    if resp == 'OK':
        email_body = data[0][1].decode('utf-8')
        mail = email.message_from_string(email_body)
        #print email_body
        if mail["Subject"].find("PA1") > 0 or mail["Subject"].find("PA2") > 0:
          regex1 = r'(?<!^)JOB:\s*(\S+)'
          #regex2 = r'Job finished'
          #c=re.findall(regex2, email_body, re.IGNORECASE)
          a=re.findall(regex1 ,email_body) #re.IGNORECASE)
          if a:
           b=set(a)
           seen = set()
           result = []
           for item in a:
              if item not in seen:
               seen.add(item)
               result.append(item)
               output = " ".join(result)
    data = [{"{#job}": output}]
    print json.dumps({"data": data}, indent=4)

并得到的实际输出

{
    "data": [
        {
            "{#job}": "example_job_1"
        }
    ]
}
{
    "data": [
        {
            "{#job}": "example_job_2"
        }
    ]
}
{
    "data": [
        {
            "{#job}": "example_job_3"
        }
    ]
}
{
    "data": [
        {
            "{#job}": "example_job_4"
        }
    ]
}

解决：“忘记”在"for循环“之前初始化空列表，因此每次迭代时都会重置列表。

tdata=[]



items = items[0].split()
for emailid in items:
    resp, data = conn.uid("fetch",emailid, "(RFC822)")
    if resp == 'OK':
        email_body = data[0][1].decode('utf-8')
        mail = email.message_from_string(email_body)
        if mail["Subject"].find("PA1") > 0 or mail["Subject"].find("PA2") > 0:
          regex1 = r'(?<!^)JOB:\s*(\S+)'
          #regex2 = r'Job finished'
          #c=re.findall(regex2, email_body, re.IGNORECASE)
          a=re.findall(regex1 ,email_body) #re.IGNORECASE)
          if a:
           b=set(a)
           seen = set()
           result = []
           for item in a:
              if item not in seen:
               seen.add(item)
               result.append(item)
               output = " ".join(result)
               tdata.append({'#job':output})
print json.dumps({"data": tdata}, indent=4)
