This project installs into an Azure Function in your Azure subscription. Its job is to read NSG Flow Logs from your configured storage account, break the data into chunks that are the right size for your log analytics system to ingest, then transmit the chunks to that system.

Settings

In the Application Settings of your Azure Function:

• AzureWebJobsStorage - required by all Azure Functions
• AzureWebJobsDashboard - required by all Azure Functions
• nsgSourceDataConnection - an Azure storage account connection string, the account where NSG flow logs land
• outputBinding - 'arcsight' (there may be other options in future)
• arcsightAddress - an IP address or DNS name for your ArcSight server/service
• arcsightPort - TCPIP port, usually 1514
• cefLogAccount - an Azure storage account connection string. Needed only if you want to log incoming JSON files and outgoing CEF files.
• logIncomingJSON - true/false
• logOutgoingCEF - true/false
