sqlclusterlog-review skillA
sqlclusterlog-review is agent-read markdown (skill) from vanterx/mssql-performance-skills: Analyzes Windows Server Failover Cluster (WSFC) CLUSTER.LOG files for Always On Availability Group root-cause diagnosis. Use this skill when an availability group has gone offline, a failover occurred unexpectedly, or a node was evicted, and you need to identify the WSFC-level cause that SQL Server DMVs cannot see. Applies 30 checks (L1–L30) covering lease timeouts, health check failures, quorum loss, node eviction, network partition, RHS crashes, AG resource transitions, Cloud Witness, Azure Ar.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# WSFC Cluster Log Review Skill ## Purpose Analyze Windows Server Failover Cluster (WSFC) CLUSTER.LOG files to diagnose Always On Availability Group failures at the cluster level — the layer below SQL Server DMVs. Applies 30 checks (L1–L30) across five categories: - **L1–L8** — File-wide patterns: lease timeouts, health check failures, RHS crashes, error bursts, repeated failover cycling, quorum loss, node eviction, log time gaps - **L9–L17** — AG resource checks: offline transitions, SQL connectivity loss, forced failovers, long pending states, DLL init failures, API timeouts, cascade failures, primary role loss, replica disconnection - **L18–L22** — Network and node: partition/split-brain, NIC failure, heartbeat timeout, witness failure, node isolation - **L23–L25** — Configuration signals: VerboseLogging=0, SeparateMonitor absent, incomplete node coverage - **L26–L30** — Modern cluster features: Cloud Witness timeout, Azure Arc agent disconnect, Contained AG system database offline, cross-subnet probe failure, sp_server_diagnostics warning ## Input Accept any of: …

How to install
mdr add vanterx/mssql-performance-skills/sqlclusterlog-review@git:20260622.55f8c85mdr add vanterx/mssql-performance-skills/sqlclusterlog-review@sha256:41c59e4aef1e7a1ePin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
