Event Hub: Microsoft Azure Functions

Coralogix provides seamless integration with Azure cloud so you can send your logs from anywhere and parse them according to your needs.

Prerequisites

• Coralogix account on the Coralogix domain corresponding to the region within which you would like your data stored
• Coralogix private key
• Azure account with an active subscription
• Active Eventhub Namespace with an Hub Named coralogix
• Azure Functions Core Tools version 4.x
• Azure CLI version 2.44.0 or later
• Node.js version 16

Installation

Clone this repo:

$ git clone https://github.com/coralogix/coralogix-azure-serverless.git
$ cd coralogix-azure-serverless/EventHub

Login with Azure cli:

$ az login

Install Azure Functions Core Tools:

$ make functools

Configure and install Coralogix function for Azure Functions. You will need to replace the following environment variables:

• Coralogix private key
• Coralogix application & subsystem names

# A Unique Identifier to ensure successful deployment of resources with universally unique requirements
export UUID=$(od -vN "7" -An -tx1 /dev/urandom|tr -d " \n"; echo)
# SAS Policy "Connection String" of EventHub Instance or Namespace
export EVENTHUB_SAS_POLICY_CONNECTION_STRING='<YOUR_AZURE_SAS_POLICY_CONNECTION_STRING>'
# Private key for Coralogix
export CORALOGIX_PRIVATE_KEY='<YOUR_PRIVATE_KEY>'
# Name of Azure EventHub to monitor
export AZURE_EVENTHUB_NAME='<YOUR_AZURE_EVENTHUB_NAME>'
# Replace the placeholder YOUR_EVENTHUB value in the function.json file
sed -i "s/YOUR_EVENTHUB/$AZURE_EVENTHUB_NAME/g" EventHub/function.json
# Desired Application name and Subsystem name for ingested EventHub messages
export CORALOGIX_APP_NAME=YOUR_APP_NAME
export CORALOGIX_SUB_SYSTEM=YOUR_SUB_SYSTEM_NAME

make install
make configure
make publish

The <YOUR_AZURE_SAS_POLICY_CONNECTION_STRING> should be replaced with Event Hub connection string which you can find in Event Hub -> Shared access policies -> Select a SAS policy -> Connection string-primary key. It should look like this:

Endpoint=sb://eventhub1.servicebus.windows.net/;SharedAccessKeyName=sas1;SharedAccessKey=TBAfq6...QLwrdeFFE=
