Filter JSON Array Using Logstash

[AJEE123 (AJ)]

Hi guys, can anybody help me?
I have JSON Array as an input like this:

"reported_devices": [
                {
                    "id": "636e6930-6361-3a65-393a-36393a31643a", 
                    "ips": [
                        {
                            "address": "10.244.0.1", 
                            "version": "v4"
                        }, 
                        {
                            "address": "fe80::c8e9:69ff:fe1d:5d39", 
                            "version": "v6"
                        }
                    ], 
                    "mac": {
                        "address": "ca:e9:69:1d:5d:39"
                    }, 
                    "name": "cni0"
                }, 
                {
                    "id": "656e7333-3536-3a36-663a-66383a63363a", 
                    "ips": [
                        {
                            "address": "10.43.2.192", 
                            "version": "v4"
                        }, 
                        {
                            "address": "fe80::546f:f8ff:fec6:fd", 
                            "version": "v6"
                        }
                    ], 
                    "mac": {
                        "address": "56:6f:f8:c6:00:fd"
                    }, 
                    "name": "ens3"
                }, 
                {
                    "id": "666c616e-6e65-6c2e-3139-653a38653a65", 
                    "ips": [
                        {
                            "address": "10.244.0.0", 
                            "version": "v4"
                        }, 
                        {
                            "address": "fe80::9c8e:eaff:fe49:6000", 
                            "version": "v6"
                        }
                    ], 
                    "mac": {
                        "address": "9e:8e:ea:49:60:00"
                    }, 
                    "name": "flannel.1"
                }, 
                {
                    "id": "63616c69-3836-6430-3838-616337343365", 
                    "ips": [
                        {
                            "address": "fe80::ecee:eeff:feee:eeee", 
                            "version": "v6"
                        }
                    ], 
                    "mac": {
                        "address": "ee:ee:ee:ee:ee:ee"
                    }, 
                    "name": "cali86d088ac743"
                }, 
                {
                    "id": "63616c69-6231-3431-6432-653938656665", 
                    "ips": [
                        {
                            "address": "fe80::ecee:eeff:feee:eeee", 
                            "version": "v6"
                        }
                    ], 
                    "mac": {
                        "address": "ee:ee:ee:ee:ee:ee"
                    }, 
                    "name": "calib141d2e98ef"
                }
            ]

I want to filter the data and get only the data for "address": "10.43.2.192" and discard the others, how to do it?

Hey,

i'm going to make this as simple as possible, you know you can parse data with the JSON filter and then access it with something like %{[reported_devices][1][ips][0][address]}

What you have to use is a ruby code to iter through the json arrays and extract values like %{[reported_devices][xx][ips][0][address]} .

What is suggest to anyone working in JSON is to try to manipulate their files trough a JSON navigator ( like dropping it into firefox ) and actually see what's the structure of the data i'm using.
