需要创建tql查询

Question

我需要创建TQL查询，以查询来自UCMDB的数据集。

我有两个问题：

1)如何找到在CIs之间存在的关系(我没有管理权限，因此需要在代码中这样做)，我需要这样做才能获得所需的数据。

2)我创建了以下查询:但我一直将IP属性值作为null。我检查了IP有一个名为ip_address的属性。

代码：

import com.hp.ucmdb.api.types.TopologyRelation;

public class Main {

    public static void main(String[] args)throws Exception {
     final String HOST_NAME = "192.168.159.132";
     final int PORT = 8080; 

     UcmdbServiceProvider provider = UcmdbServiceFactory.getServiceProvider(HOST_NAME, PORT);

     final String USERNAME = "username";

     final String PASSWORD = "password";

     Credentials credentials = provider.createCredentials(USERNAME, PASSWORD);

     ClientContext clientContext = provider.createClientContext("Test");
     UcmdbService ucmdbService = provider.connect(credentials, clientContext);

     TopologyQueryService queryService = ucmdbService.getTopologyQueryService();

     Topology topology = queryService.executeNamedQuery("Host IP");

     Collection<TopologyCI> hosts = topology.getAllCIs(); 

     for (TopologyCI host : hosts) { 


      for (TopologyRelation relation : host.getOutgoingRelations()) { 
       System.out.print("Host " + host.getPropertyValue("display_label")); 
       System.out.println (" has IP " + relation.getEnd2CI().getPropertyValue("ip_address")); 

      } 
     }

}

在上面的查询输出中:我得到带有IP = null的主机名

我在JYthon中有一个示例查询，我无法找出:它只适用于上面的代码。

任何能理解它的人都会把它附上去。

import sys

UCMDB_API="c:/ucmdb/api/ucmdb-api.jar"

sys.path.append(UCMDB_API)

from com.hp.ucmdb.api import *

# 0) Connection settings
HOST_NAME="192.168.159.132"
PORT=8080

USERNAME="username"
PASSWORD="password"

# 1) Get a Service Provider from the UcmdbServiceFactory
provider = UcmdbServiceFactory.getServiceProvider(HOST_NAME, PORT)

# 2) Setup credentials to log in
credentials = provider.createCredentials(USERNAME, PASSWORD)

# 3) Create a client context
clientContext = provider.createClientContext("TESTING")

# 4) Connect and retrieve a UcmdbService object
ucmdbService = provider.connect(credentials, clientContext)

# 5) Get the TopologyQueryService from the UcmdbService
queryService = ucmdbService.getTopologyQueryService()

# ======= Everything After this is specific to the query =======

# 6) Execute a Named Query and get the Topology
topology = queryService.executeNamedQuery('Host IP')

# 7) Get the hosts
hosts = topology.getAllCIs()

# 8) Print the hosts and IPs
host_ip = {}

for host in hosts:
    host_name = host.getPropertyValue("display_label")
    if host_name in host_ip.keys():
        ips = host_ip[host_name]
    else:
        ips = {} 
        host_ip[host_name] = ips
    for relation in host.getOutgoingRelations():
        ip_address = relation.getEnd2CI().getPropertyValue("display_label")
        if ip_address in ips.keys():
            pass
        else:
            ips[ip_address] = ''
            print "%s , %s" % (host_name, ip_address)

请帮帮忙。

我无法理解如何进一步解决这一问题。

谢谢。

最简单的修复方法是使用IP地址CI中的display_label属性，而不是ip_address属性。Jython参考代码使用display_label作为其逻辑。

我有点担心使用display_label，因为display_label格式逻辑可以更改为不显示IP CIs的IP地址。直接从ip_address属性获取数据是一个更好的选择，如果定义了TQL返回该数据，则应该可以工作。检查Host并确保它被配置为返回IP CIs的ip_address。
