It reads existing Azure Monitor platform metrics with no data migration or configuration needed, provided the user has Reader access to a subscription. Features include account discovery, fleet health overview, performance comparison across accounts, basic security triage signals (Entra ID auth, customer-managed keys, public network access), and the ability to create new Cosmos DB for NoSQL accounts. Limitations include no Copilot/agent support for Cosmos DB data, metric-only (not query-level) monitoring, account creation being the only management action, a 100-resource cap on performance dashboards, and no support for Fabric-native Cosmos DB or Fleet Analytics. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What can I do with Azure Cosmos DB support in Fabric Database Hub public preview? The public preview lets you discover and monitor Azure Cosmos DB accounts across subscriptions from a single Database Hub view, without moving data into Fabric or enabling diagnostic logs. It reads existing Azure Monitor platform metrics, shows fleet health and performance comparisons across up to 100 resources, surfaces three security triage signals, and supports creating new Cosmos DB for NoSQL accounts, but not scaling or reconfiguring existing ones. _daily.dev surfaces updates like this for teams tracking new ways to monitor Cosmos DB estates._ ### What permissions do I need to use Azure Cosmos DB in Fabric Database Hub? You need a Fabric tenant with a Fabric or Fabric Trial capacity assigned to your workspace, plus Reader access (or greater) at subscription scope to discover and monitor accounts. To create accounts from Database Hub, you also need Cosmos DB Operator access (or greater) at resource group scope. Seeing an account in Estate does not grant data access; querying still requires a data plane role assignment and network access. _Engineers setting up access controls for Cosmos DB monitoring can track these permission details on daily.dev._ ### What are the limitations of the Azure Cosmos DB Fabric Database Hub preview? Copilot and agents cannot yet answer questions about Cosmos DB data in Database Hub, monitoring is limited to a curated subset of Azure Monitor metrics without query-level diagnostics or hot-spot analysis, management is limited to account creation only, and the performance dashboard caps at 100 resources per view. Fabric-native Cosmos DB and Cosmos DB Fleet Analytics are not supported in this preview. _daily.dev helps engineers evaluating Cosmos DB tooling stay aware of preview-stage gaps before relying on them._ ## Similar posts on daily.dev - [Announcing the Private Preview of Cosmos DB Azure RBAC Integration](https://daily.dev/posts/announcing-the-private-preview-of-cosmos-db-azure-rbac-integration-l6k2jme1h) · DevBlogs · 0 upvotes · 0 comments - [Public Preview: Cosmos DB Mirroring in Microsoft Fabric with Private Endpoints](https://daily.dev/posts/public-preview-cosmos-db-mirroring-in-microsoft-fabric-with-private-endpoints-nx3sclibl) · DevBlogs · 0 upvotes · 0 comments --- Tags: [#database](https://daily.dev/tags/database), [#azure](https://daily.dev/tags/azure), [#backend](https://daily.dev/tags/backend), [#azure-cosmos-db](https://daily.dev/tags/azure-cosmos-db), [#microsoft-fabric](https://daily.dev/tags/microsoft-fabric) [View this post on daily.dev](https://daily.dev/posts/announcing-public-preview-for-azure-cosmos-db-in-fabric-database-hub--q3f9d7jz6) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Announcing Public Preview for Azure Cosmos DB in Fabric Database Hub!","url":"https://daily.dev/posts/announcing-public-preview-for-azure-cosmos-db-in-fabric-database-hub--q3f9d7jz6","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/announcing-public-preview-for-azure-cosmos-db-in-fabric-database-hub--q3f9d7jz6"},"datePublished":"2026-09-29T07:02:43.239Z","dateModified":"2026-09-29T07:03:13.063Z","description":"Azure Cosmos DB support in Fabric Database Hub is now in public preview, letting customers discover and monitor Cosmos DB accounts alongside other Microsoft...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/db192be6977970350d45d9b04627d7fa?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/db192be6977970350d45d9b04627d7fa?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"DevBlogs","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"DevBlogs","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/8f68b453325f482ebeb73fb780092713","url":"https://daily.dev/sources/devblogs"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/announcing-public-preview-for-azure-cosmos-db-in-fabric-database-hub--q3f9d7jz6","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":1},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"database,azure,backend,azure-cosmos-db,microsoft-fabric","timeRequired":"PT5M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"DevBlogs","item":"https://daily.dev/sources/devblogs"},{"@type":"ListItem","position":3,"name":"Announcing Public Preview for Azure Cosmos DB in Fabric Database Hub!"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/announcing-public-preview-for-azure-cosmos-db-in-fabric-database-hub--q3f9d7jz6#faq","mainEntity":[{"@type":"Question","name":"What can I do with Azure Cosmos DB support in Fabric Database Hub public preview?","acceptedAnswer":{"@type":"Answer","text":"The public preview lets you discover and monitor Azure Cosmos DB accounts across subscriptions from a single Database Hub view, without moving data into Fabric or enabling diagnostic logs.
