opensearch-diagnostics

Use this skill to investigate and troubleshoot Amazon OpenSearch Service problems (managed clusters and Serverless collections) by analyzing domain configurations, cluster health, indexing failures, search performance, storage pressure, JVM memory, shard management, snapshot/restore, access policies, VPC connectivity, Dashboards, UltraWarm/cold storage, and Serverless issues. Activate when: cluster health RED or YELLOW, search latency, indexing failures or throughput degradation, JVM memory pressure or GC pauses, disk watermark breaches, storage full, shard imbalance or unassigned shards, too many shards, mapping conflicts, bulk indexing errors, access policy denials, fine-grained access control (FGAC) issues, VPC connectivity problems, snapshot failures, restore issues, repository configuration, Dashboards access or visualization errors, UltraWarm or cold storage tier issues, ISM policy failures, index rollover problems, Serverless collection issues, Serverless capacity/scaling, split brain, dedicated master

Activate when: cluster health RED or YELLOW, search latency, indexing failures or throughput degradation, JVM memory pressure or GC pauses, disk watermark breaches, storage full, shard imbalance or unassigned shards, too many shards, mapping conflicts, bulk indexing errors, access policy denials, fine-grained access control (FGAC) issues, VPC connectivity problems, snapshot failures, restore issues, repository configuration, Dashboards access or visualization errors, UltraWarm or cold storage tier issues, ISM policy failures, index rollover problems, Serverless collection issues, Serverless capacity/scaling, split brain, dedicated master node issues, or the user says something is wrong with OpenSearch without naming specific symptoms.
compatibility	Requires AWS CLI or SDK access with OpenSearch Service, CloudWatch, CloudTrail, EC2 (for VPC/security groups), IAM, and optionally S3/KMS permissions. OpenSearch REST API access via curl recommended for direct cluster diagnostics.
