Use this skill for any Kusto query or telemetry investigation specifically related to Fluid Framework or its partners. Triggers include: writing or running a Kusto query against the Office Fluid database, investigating Fluid Framework telemetry or error rates, querying Office_Fluid_FluidRuntime_* tables, looking up a Fluid session by Session_Id or docId, investigating a Fluid-related error in Loop or Whiteboard telemetry, monitoring an FF bump or partner ring deployment, checking Fluid render re

Fluid Framework Kusto Reference
This skill provides a comprehensive reference for Fluid Framework telemetry investigation in Kusto. Load it whenever a Kusto query needs to be written, interpreted, or run against the Office Fluid database.
VPN required. The Office Fluid Kusto cluster (https://kusto.aria.microsoft.com) is only reachable on the Microsoft internal network. If a query fails to connect or returns no results unexpectedly, remind the user to check that their VPN is on before troubleshooting further.
Cluster & Access
Cluster:https://kusto.aria.microsoft.com
Primary database:Office Fluid
Database ID:6a8929bcfc6d44e9b13fee392ada9cf0 (use this, not the pretty name, as the database parameter in kusto_query)
Automation/stress test database:Office Fluid Test
Database ID:742fa5a288b045e5beab1a2b8e445a71 — contains office_fluid_ffautomation_* tables used for stress test / pipeline telemetry. These tables are NOT in the primary "Office Fluid" database.
Retention: ~28 days
VPN: Required (Microsoft internal network)
Access requirement: M365HeartbeatTenantUsers group membership
Quick Orientation
The primary tables are:
Office_Fluid_FluidRuntime_Error — all errors (first stop)
Key deployment ring field: Loop_Audience (FluidRuntime tables), Release_AudienceGroup (OWH/QoS tables)
Using the Full Reference
Before writing any non-trivial Kusto query, read the full reference file:
references/kusto-query-reference.md
This reference contains:
Part 1 — All tables, fields, correlation IDs, version fields, stored functions, partner database schemas (OneNote, OWA, Loop FFX, Video, Scriptor, HostTracker, automation)
Part 2 — Query Cookbook with ~20 sections of ready-to-use queries (session lookup, error timecharts, breadth assessment, version correlation, ICE rate calculations, EU global queries, ODSP flight changes, etc.)
Part 3 — Investigation playbook patterns (incoming partner incident, dataCorruptionError triage, ICE error rate, important notes)
