How to get systemId field value using logstash-input-azure\_blob\_storage? please HELP!

The Azure NSG log format is described here:

> **[Introduction to flow logging for NSGs - Azure Network Watcher](https://docs.microsoft.com/en-us/azure/network-watcher/network-watcher-nsg-flow-logging-overview)**
>
> This article explains how to use the NSG flow logs feature of Azure Network Watcher.

my logstash.conf file contents:

input {  
azure\_blob\_storage  
{  
storageaccount =\> "tfintegration"  
access\_key =\> "correct access\_key"  
container =\> "insights-logs-networksecuritygroupflowevent"  
codec =\> "json"  
logtype =\> "nsgflowlog"  
prefix =\> "resourceId=/"  
registry\_create\_policy =\> "resume"  
interval =\> 10  
}  
}

output {  
file {  
path =\> "/tmp/s21"  
}  
}

sample record in /tmp/s21 (it does not have systemId):

{"@timestamp":"2020-03-07T14:31:05.563Z","@version":"1","message":"{"subscription":"3AA9C5F1-91B2-4438-960A-16FB1B3B43F3","resourcegroup":"DEFAULTRESOURCEGROUP-EUS","nsg":"TFINTEGRATIONVM1-NSG","rule":"DefaultRule\_DenyAllInBound","unixtimestamp":"1583591307","src\_ip":"185.176.27.98","dst\_ip":"10.1.0.4","src\_port":"43018","dst\_port":"11291","protocol":"T","direction":"I","decision":"D","flowstate":"B","src\_pack":null,"src\_bytes":null,"dst\_pack":null,"dst\_bytes":null}"}
