New features
Installation
More secure ways to get BigQuery data for Unravel monitoring
You can set up Unravel, using any of the following secure authentication methods, to receive data from BigQuery for Unravel monitoring.
VM-based authentication: This method is used when Unravel is hosted on a VM in the GCP compute engine service.
In this method, a service account is created in the project in which Unravel is hosted. Instead of downloading the service account key, the service account is attached to the Unravel VM.
Single key-based authentication: This method is ideal for cases where Unravel is installed on a VM that is hosted outside GCP on any other cloud or on-prem environment.
Only one service account key representing all the projects is integrated with Unravel, which is downloaded and used. This method lets you use a single key instead of multiple keys to help in key rotation.
Terraform is separately provided independent of the installer
Terraform is an open-source software for infrastructure provisioning. The Terraform creates resources on the GCP account and facilitates the smooth integration of Unravel with your cloud platform. Terraform is now provided in both ways; bundled with the installer as well as separated from the installer for independent handling of resource creation and state management.
The external Terraform is available for all the authentication (VM authentication, Single key authentication, and Multiple key authentication) methods available for integrating BigQuery projects.
Refer to BigQuery installation in Installing Unravel.
Support for integration of administration projects
The integration of administrator projects is now supported. These projects help in retrieving reservations data required for Cost 360 observability dashboards.
Support for integrating billing data
You can now export and integrate BigQuery billing data for Unravel querying.
Capture complete cost
Unravel can now capture the complete cost concerning BigQuery, which includes computing, storage, and services. For computing, Unravel can capture the cost for both on-demand and capacity-based (Standard, Enterprise, Enterprise Plus) pricing plans.
