Intelligently Detect Exceptions with One Line of Code: UModel PaaS API Architecture Design and Best Practices

This article introduces a unified UModel PaaS API that abstracts complex observability data access into simple one-line queries for intelligent exception detection. Background For observability systems built on UModel, accessing observability data requires upper-layer applications to be aware of multiple concepts such as EntitySet, DataSet, Storage, and Filter. This brings high development and maintenance costs to users such as UI, algorithms, and customers. Typical Scenario: Querying Request Metrics of an APM Service Assume that an upper-layer application needs to query a specific application performance management (APM) service's request metrics. The developer needs to go through the following steps: What developers need to know Entity association: Which MetricSet is the service entity associated with? Storage routing: Which MetricStore does the MetricSet use? What are the region, project, and storage names? Field mapping: Which field (e. g. acs_arms_service_id) of the storage corres
