Hello,

 

I am looking for a script to get values of Security Zone attribute from Security Zone Cache node and  CI attribute from Configuration Items node in below sample JSON payload.

 

Based on below sample JSON payload, script should return Security Zone as COR and CI should be dcscapengMID001.

 

 

{"1.3.1.1":{"Configuration Items":{"table_name":"cmdb_ci_hardware","cmdb_ci_hardware-query":"ip_address=10.39.145.142^ORsys_idIN8bafe2e4db072150966c676ed396194c,8bafe2e4db072150966c676ed396194c^install_status!=7","results":[{"CI":"dcscapengMID001","Serial Number":"ee11ff7f-e6ff-49bb-857a-1175883319e8","Reporting Realm":"Core","Status":"Installed","sys_id":"8bafe2e4db072150966c676ed396194c"}]},"Network Adapters":{"table_name":"cmdb_ci_network_adapter","cmdb_ci_network_adapter-query":"ip_address=10.39.145.142^install_status!=7","results":[{"Nic":"Ethernet 1","CI":"dcscapengMID001","Reporting Realm":"Core","CI Status":"Installed","sys_id":"d3afe2e4db072150966c676ed396195e"}]},"IP Addresses":{"table_name":"cmdb_ci_ip_address","cmdb_ci_ip_address-query":"ip_address=10.39.145.142^install_status!=7","results":[{"IP":"10.39.145.142","CI":"dcscapengMID001","Reporting Realm":"Core","CI Status":"Installed","sys_id":"ad842bf71bbc0650f3fa2066b04bcb06"}]},"NCM Load Balancer VIP":{"table_name":"u_ncm_cache_lbc_virtual_ip","u_ncm_cache_lbc_virtual_ip-query":"u_address=10.39.145.142/32","results":[]},"IPAM Cache":{"table_name":"u_ipam_cache","u_ipam_cache-query":"u_starting_ip_int<=1.70365326E8^u_ending_ip_int>=1.70365326E8","results":[{"CIDR":"10.0.0.0/8","Type":"Aggregate","Sub Type":"","Reporting Realm":"","Security Zone":"","sys_id":"93f9167b1bfcee94c5c320e4604bcb98"},{"CIDR":"10.0.0.0/8","Type":"Prefix","Sub Type":"Active","Reporting Realm":"Core","Security Zone":"","sys_id":"7a61d3331b78aa944accec21604bcb20"},{"CIDR":"10.32.0.0/12","Type":"Prefix","Sub Type":"Container","Reporting Realm":"Core","Security Zone":"","sys_id":"ba13d33b1b78aa944accec21604bcbd3"},{"CIDR":"10.38.0.0/15","Type":"Prefix","Sub Type":"Container","Reporting Realm":"Core","Security Zone":"","sys_id":"96835f7b1b78aa944accec21604bcb4f"},{"CIDR":"10.39.128.0/18","Type":"Prefix","Sub Type":"Active","Reporting Realm":"Core","Security Zone":"COR","sys_id":"1293df7b1b78aa944accec21604bcb12"},{"CIDR":"10.39.144.0/22","Type":"Prefix","Sub Type":"Active","Reporting Realm":"Core","Security Zone":"None","sys_id":"a293df7b1b78aa944accec21604bcb15"}]},"Security Zone Cache":{"table_name":"u_subnet_nsz","u_subnet_nsz-query":"u_starting_ip_int<=1.70365326E8^u_ending_ip_int>=1.70365326E8","results":[{"CIDR":"10.39.128.0/18","Security Zone":"COR","sys_id":"7c02c775dbd0d81049217a8eaf9619ed"}]},"Unknown IP From Scan":{"table_name":"u_unknown_ip","u_unknown_ip-query":"u_ip_address=10.39.145.142","results":[{"IP":"10.39.145.142","Found":"Yes","Reporting Realm":"Core","sys_id":"6adab2711b32d294a5db0d03604bcbfb"}]},"Unknown CIDR Reason":{"table_name":"u_unknown_cidr_exclusion","u_unknown_cidr_exclusion-query":"u_starting_ip_int<=1.70365326E8^u_ending_ip_int>=1.70365326E8","results":[]}}}

 

I tried below OOB API to parse these values.But, it's not working for me.

Hi @Sam121 
You can try the below script, if the results contain more than one array element.

var str = '{"1.3.1.1":{"Configuration Items":{"table_name":"cmdb_ci_hardware","cmdb_ci_hardware-query":"ip_address=10.39.145.142^ORsys_idIN8bafe2e4db072150966c676ed396194c,8bafe2e4db072150966c676ed396194c^install_status!=7","results":[{"CI":"dcscapengMID001","Serial Number":"ee11ff7f-e6ff-49bb-857a-1175883319e8","Reporting Realm":"Core","Status":"Installed","sys_id":"8bafe2e4db072150966c676ed396194c"}]},"Network Adapters":{"table_name":"cmdb_ci_network_adapter","cmdb_ci_network_adapter-query":"ip_address=10.39.145.142^install_status!=7","results":[{"Nic":"Ethernet 1","CI":"dcscapengMID001","Reporting Realm":"Core","CI Status":"Installed","sys_id":"d3afe2e4db072150966c676ed396195e"}]},"IP Addresses":{"table_name":"cmdb_ci_ip_address","cmdb_ci_ip_address-query":"ip_address=10.39.145.142^install_status!=7","results":[{"IP":"10.39.145.142","CI":"dcscapengMID001","Reporting Realm":"Core","CI Status":"Installed","sys_id":"ad842bf71bbc0650f3fa2066b04bcb06"}]},"NCM Load Balancer VIP":{"table_name":"u_ncm_cache_lbc_virtual_ip","u_ncm_cache_lbc_virtual_ip-query":"u_address=10.39.145.142/32","results":[]},"IPAM Cache":{"table_name":"u_ipam_cache","u_ipam_cache-query":"u_starting_ip_int<=1.70365326E8^u_ending_ip_int>=1.70365326E8","results":[{"CIDR":"10.0.0.0/8","Type":"Aggregate","Sub Type":"","Reporting Realm":"","Security Zone":"","sys_id":"93f9167b1bfcee94c5c320e4604bcb98"},{"CIDR":"10.0.0.0/8","Type":"Prefix","Sub Type":"Active","Reporting Realm":"Core","Security Zone":"","sys_id":"7a61d3331b78aa944accec21604bcb20"},{"CIDR":"10.32.0.0/12","Type":"Prefix","Sub Type":"Container","Reporting Realm":"Core","Security Zone":"","sys_id":"ba13d33b1b78aa944accec21604bcbd3"},{"CIDR":"10.38.0.0/15","Type":"Prefix","Sub Type":"Container","Reporting Realm":"Core","Security Zone":"","sys_id":"96835f7b1b78aa944accec21604bcb4f"},{"CIDR":"10.39.128.0/18","Type":"Prefix","Sub Type":"Active","Reporting Realm":"Core","Security Zone":"COR","sys_id":"1293df7b1b78aa944accec21604bcb12"},{"CIDR":"10.39.144.0/22","Type":"Prefix","Sub Type":"Active","Reporting Realm":"Core","Security Zone":"None","sys_id":"a293df7b1b78aa944accec21604bcb15"}]},"Security Zone Cache":{"table_name":"u_subnet_nsz","u_subnet_nsz-query":"u_starting_ip_int<=1.70365326E8^u_ending_ip_int>=1.70365326E8","results":[{"CIDR":"10.39.128.0/18","Security Zone":"COR","sys_id":"7c02c775dbd0d81049217a8eaf9619ed"}]},"Unknown IP From Scan":{"table_name":"u_unknown_ip","u_unknown_ip-query":"u_ip_address=10.39.145.142","results":[{"IP":"10.39.145.142","Found":"Yes","Reporting Realm":"Core","sys_id":"6adab2711b32d294a5db0d03604bcbfb"}]},"Unknown CIDR Reason":{"table_name":"u_unknown_cidr_exclusion","u_unknown_cidr_exclusion-query":"u_starting_ip_int<=1.70365326E8^u_ending_ip_int>=1.70365326E8","results":[]}}}';

var ci_obj = obj['1.3.1.1']['Configuration Items']['results'];
var ci_arr = [];
for (var i = 0; i < ci_obj.length; i++) {
    ci_arr.push(ci_obj[i]['CI']);

@Sam121 

try this and it worked for me

(function extractValues() {
    var jsonPayload = {

                "results": [{

            }
        }
    };

    // Extract CI from Configuration Items
    var ci = jsonPayload["1.3.1.1"]["Configuration Items"]["results"][0]["CI"];

    // Extract Security Zone from Security Zone Cache
    var securityZone = jsonPayload["1.3.1.1"]["Security Zone Cache"]["results"][0]["Security Zone"];

    // Output the extracted values
    gs.info("CI: " + ci);
    gs.info("Security Zone: " + securityZone);
})();
