It reports, in real time, whether the platform's core dependencies are reachable and correctly configured: * **Infrastructure**: Database, search index, schema migrations * **Search**: Search reindex status, semantic search embeddings (when enabled) * **External dependencies**: Authentication keys, ingestion service, log storage (when configured), object storage * **Collate AI**: AI Platform, NLQ Hybrid Search (reports as disabled when not configured) Run it first whenever something feels off elsewhere in Collate. A stuck ingestion pipeline or missing search results often trace back to one of these checks failing. **Purpose and Benefits** * **Purpose**: Check live status of the platform's core dependencies, such as the database and search index. * **Benefits**: Gives you one place to look before troubleshooting an issue anywhere else. ## How to Check To check platform health, follow the steps below: 1. Click the **Profile** icon and navigate to **Settings** > **Preferences** > **Health Check**. Health Check panel 2. Review the status of each check: **Infrastructure** * **Database**: Connectivity to the metadata database. If this fails, nothing in Collate can read or write metadata. * **Search Instance**: Connectivity to the search/index cluster. If this fails, search, discovery, and lineage graphs stop returning results. * **Migrations**: That all expected schema migrations have run. An incomplete migration can cause unpredictable errors elsewhere until it's resolved. **Search** * **Search Reindex Status**: That every deployed search index was built from the current index mapping, so no reindex is pending. A pending reindex means some assets may not appear in search until it completes. * **Semantic Search**: That the embeddings used for semantic search are working, shown only when semantic search is enabled. If this fails, natural-language search falls back to keyword matching. **External dependencies** * **Pipeline Service Client**: Connectivity to the ingestion pipeline service. If this fails, no ingestion or profiler workflow can be triggered. * **JWKs**: That the configured JWKS (JSON Web Key Set) validates correctly. If this fails, token-based authentication can break for some or all users. * **Log Storage**: Connectivity to S3 log storage, shown only when S3 storage is configured. If this fails, ingestion runner logs aren't retrievable from the UI. * **Object Storage**: Connectivity to object storage used for uploaded file content, for example Context Center Drive. If this fails, uploaded files become unreachable. **Collate AI** * **AI Platform**: That the AI Platform powering Collate AI and AI Agents is reachable. If this fails, Collate AI features and AI Agents stop working. * **NLQ Hybrid Search**: That natural language search's LLM-backed filter extraction is configured and initialized. Always shown, and reports as failed with an "NLQ Hybrid Search is not enabled" message when the feature is off. Health Check results 3.
