 In this article, you learn how to selectively read portions of Azure Network Watcher flow logs using PowerShell without having to parse the entire log. Flow logs are stored in a storage account in block blobs. Each log is a separate block blob that is generated every hour and updated with the latest data every few minutes. Using the script provided in this article, you can read the latest data from the flow logs without having to download the entire log.
 
 The concepts discussed in this article aren't limited to the PowerShell and are applicable to all languages supported by the Azure Storage APIs.

 [Network security group flow logs](nsg-flow-logs-overview.md) provide information that you can use to understand ingress and egress IP traffic for Azure network interfaces. Flow logs show outbound and inbound flows on a per network security group rule basis, the network interface the flow applies to, 5-tuple information (Source/Destination IP, Source/Destination Port, Protocol) about the flow, and if the traffic was allowed or denied.
 
 You can have many network security groups in your network with flow logging enabled. Several network security groups with flow logging enabled can make it cumbersome to parse and gain insights from your logs. This article provides a solution to centrally manage these network security group flow logs using Graylog, an open source log management and analysis tool, and Logstash, an open source server-side data processing pipeline.
