Prerequisites

To integrate with Qualys VM KnowledgeBase (using Azure Functions) make sure you have:

Vendor installation instructions

NOTE: This data connector depends on a parser based on a Kusto Function to work as expected which is deployed as part of the solution. To view the function code in Log Analytics, open Log Analytics/Microsoft Sentinel Logs blade, click Functions and search for the alias QualysVM Knowledgebase and load the function code or click here, on the second line of the query, enter the hostname(s) of your QualysVM Knowledgebase device(s) and any other unique identifiers for the logstream. The function usually takes 10-15 minutes to activate after solution installation/update.

This data connector depends on a parser based on a Kusto Function to work as expected. Follow the steps to use the Kusto function alias, QualysKB

(Optional Step) Securely store workspace and API authorization key(s) or token(s) in Azure Key Vault. Azure Key Vault provides a secure mechanism to store and retrieve key values. Follow these instructions to use Azure Key Vault with an Azure Function App.
