SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill enables analysts to access Mozilla Splunk Cloud and retrieve Azure activity logs to understand VM provisioning and lifecycle events for Taskcluster workers, bridging gaps between Azure actions and worker-manager signals.

Core Features & Use Cases

  • Query Splunk Cloud for index=azure_audit to inspect VM create/write/delete events and outcomes (Start, Success, Failure) for pools like RG-TC-GECKO-T-WIN11-64-25H2.
  • Build VM end-to-end timelines and correlate with other sources such as tc-logview and papertrail to diagnose provisioning issues like OSProvisioningTimedOut.
  • Use Splunk Web automation through browser-harness to script and repeat investigations for different pools or time windows.

Quick Start

Start by running a Splunk search against index=azure_audit for a specific RG and time window to begin investigating a VM provisioning event.

FAQPage Schema
How do I query Splunk Cloud for Taskcluster VM lifecycle events?

Query the azure_audit index in Splunk Cloud to identify Azure provisioning events for Taskcluster worker VMs, revealing VM writes, starts, and deletes. Search specific resource groups like RG-TC-GECKO-T-WIN11-64-25H2 to retrieve results.

What is the best way to diagnose OSProvisioningTimedOut failures for Taskcluster workers?

Diagnose OSProvisioningTimedOut failures by querying Splunk Cloud's azure_audit index for VM provisioning events. Correlate these Azure activity logs with worker-manager signals to bridge gaps and identify the root cause of the timeout.

Can I use Splunk Web automation to investigate multiple Taskcluster resource pools?

Yes, you can use Splunk Web automation via browser-harness to script and repeat investigations for different Taskcluster pools or time windows. This allows you to systematically query the azure_audit index across various resource group patterns.

How do I build a VM end-to-end timeline using Azure audit logs?

Build a VM end-to-end timeline by querying the azure_audit index in Splunk Cloud for VM writes, starts, and deletes. Retrieve these Azure activity logs and correlate them with tc-logview and papertrail to map the full VM lifespan and provisioning outcomes.

Does querying Splunk Cloud for Azure activity logs require an authenticated browser session?

Yes, querying Splunk Cloud for Azure activity logs uses browser-harness to drive Splunk Web in authenticated Chrome sessions. This approach automates the retrieval of azure_audit index data to investigate VM provisioning and lifecycle events.
