Kyma Integration with SAP Cloud Logging. Part 2: Let's ship some tracesKyma Integration with SAP Cloud Logging. Part 2: Let's ship some tracesWalks through shipping traces from SAP BTP, Kyma runtime to SAP Cloud Logging: a Kyma TracePipeline resource pointed at the service binding's OTLP endpoint, an Istio Telemetry resource that sets the mesh-wide sampling percentage, and Cloud Logging's Trace Analytics view to filter the resulting spans by service name or request ID. For a multitenant JavaScript CAP application it instruments with @cap-js/telemetry, naming the npm packages to add, and covers Cloud Native Buildpacks and manual Istio header propagation for services outside CAP.gabbi, published 2024-04-19
Don't "let it crash", is this the new CAP guideline?Don't "let it crash", is this the new CAP guideline?Dinu traces a change in error handling in CAP's Node.js runtime: @sap/cds@8.2.0 adds a cds.server.shutdown_on_uncaught_errors config flag, defaulting to true, but invoking an operation with an undefined variable no longer takes the server down, with or without the flag, where the same code crashed it on cds@6 and cds@7, and the author notes the old behaviour was already missing in cds@8.1. It still crashes with features.odata_new_adapter turned off to use the old OData parser, so it is the new OData adapter, like the REST adapter before it, that answers an uncaught error with a 500 instead of taking the process down.Dinu, published 2024-09-06
SAP CAP Lessons Learned: Run a CAP app using SQLite on SAP BTP - Cloud FoundrySAP CAP Lessons Learned: Run a CAP app using SQLite on SAP BTP - Cloud FoundrySQLite past the point it is meant to go — deployed, not local. Written as a lesson learned rather than a recommendation, and it pairs with the author's own note that SQLite is single threaded.LucasMagriniRigo, published 2024-12-30
Using Github Actions to Deploy a CAP App (MTA)Using Github Actions to Deploy a CAP App (MTA)Walks through a GitHub Actions workflow that deploys a CAP project's MTA to SAP BTP, Cloud Foundry: secrets and variables for the BTP credentials, a push-triggered job that checks out the repository, installs Node.js, runs npx mbt build and then cf deploy against the target org and space, plus an optional test job and a note on reusable workflow templates. Written because capire's own CI/CD guide is Docker-based and the linked sample is marked broken, so this fills the gap with the plain cds add mta / mbt build / cf deploy sequence driven by a pipeline instead of a terminal. That sequence is exactly what cds up, beta since @sap/cds-dk 8.9.0 (March 2025), now runs as one command, so the pipeline mechanics still hold but the three manual build-and-deploy steps it scripts are no longer the only way there.Christopher_Ketzler, published 2024-08-26
From Application Logging to Cloud Logging: Service Innovation GuideFrom Application Logging to Cloud Logging: Service Innovation GuideSAP Cloud Logging replaces SAP Application Logging service, moving each customer from a shared multitenant stack to a dedicated, fully isolated one, and this guide sets out what changes with the move: a deployment per compliance region instead of per Cloud Foundry landscape, SAML/IDP-based authentication instead of Cloud Foundry-bound auth, retention that is configurable instead of fixed at seven days, and hourly capacity-unit pricing instead of fixed-size monthly plans. It also states the deprecation timeline for logging on BTP: SAP Application Logging closes to new or renewed CPEA contracts after 2025-07-31, while contracts signed before that date keep their entitlement until their next renewal.Hariharan-Gandhi, published 2024-11-22
From Application Logging to Cloud Logging: Service Migration GuideFrom Application Logging to Cloud Logging: Service Migration GuideA six-step guide to moving off SAP Application Logging service for SAP BTP onto SAP Cloud Logging: plan the instance layout, set up an Identity Authentication Service tenant for single sign-on to the new service, bind applications to both services in parallel so log data flows to each for comparison, then deprovision the old service once Cloud Logging holds the retained history. It covers what the logging libraries need so custom fields reach both services during the overlap: the CF Node.js library detects both bindings itself from v6.5.0, while the CF Java library has to be configured to retain each custom field at top level. It also gives the deprecation date SAP published for Application Logging under CPEA contracts, 31 July 2025.Hariharan-Gandhi, published 2024-11-22
Kyma Integration with SAP Cloud Logging. Part 1: Introduction and shipping LogsKyma Integration with SAP Cloud Logging. Part 1: Introduction and shipping LogsProvisions an SAP Cloud Logging instance for SAP BTP, Kyma runtime and ships application and Istio access logs to it through Kyma's Telemetry module, using LogPipeline custom resources that name the source namespaces and the target instance's credentials. Walks through the kubectl commands and example LogPipeline configuration for both an application's own logs and Istio's access logs, then how to browse the result in OpenSearch and the built-in Four Golden Signals dashboard. First of a three-part series; traces and metrics are left to the posts that follow.gabbi, published 2024-03-25

Performance Trace Node.js App on BTP with DynatracePerformance Trace Node.js App on BTP with DynatraceWalks through wiring Dynatrace as a third-party APM for a Node.js app on SAP BTP, as an alternative to the platform's own internal monitoring: creating an access token and a user-provided service instance, binding it in manifest.yaml, and adding the @dynatrace/oneagent-sdk package for distributed tracing across app router, IDP and connectivity-proxy hops. An appendix covers turning on @sap/approuter's debug-level log output through the XS_APP_LOG_LEVEL environment variable.jeremy_ma_usa, published 2024-09-04
SAP Cloud Logging Serviceでコンテナメトリクスを監視するSAP Cloud Logging Serviceでコンテナメトリクスを監視するIn Japanese. Container metrics for a CAP Node.js application into SAP Cloud Logging Service, and the reason it exists is that the obvious route does not apply: Spring Boot Actuator covers the Java side, and Node has no equivalent, so the author reaches for Telegraf instead. The procedure is deliberately independent of application logic — bind the instance, add a startup script and a config file — so it works against an application you already have.kyoneo, published 2024-03-26
Unleashing ABAP Potential: An introduction to Extension Libraries (XCO)Unleashing ABAP Potential: An introduction to Extension Libraries (XCO)Introduces ABAP's Extension Libraries (XCO), a library framework that puts reusable functionality behind one interface. The post places it as part of the ABAP RESTful Application Programming Model but versatile enough for other ABAP contexts, and says it works in both on-premise ABAP and the ABAP environment on SAP Business Technology Platform. It walks through a worked Logging example: xco_log=>factory->create_new_log opens a log keyed by object, subobject and external ID, logger->add_message appends a typed message, and logger->add_last_symsg attaches a problem class and level of detail for later traceability.tamitdassharma, published 2024-11-27
Event-Driven Multi-Tenant Architecture on SAP BTP with CAP and SAP Event MeshEvent-Driven Multi-Tenant Architecture on SAP BTP with CAP and SAP Event MeshThe two topics that are usually written about separately, taken together — because a shared broker is where tenant isolation stops being automatic. It starts from why microservices are decoupled at all, places Event Mesh among the four broker services BTP offers, and then works through what changes when the publisher and the consumer are multitenant.ale_biagi, published 2024-12-19
Adding Custom Metrics to a CAP application using cap-js/telementry plugin and SAP Cloud LoggingAdding Custom Metrics to a CAP application using cap-js/telementry plugin and SAP Cloud LoggingWalks through adding a custom OpenTelemetry counter metric to a CAP application on top of @cap-js/telemetry's built-in database-pool metrics, incrementing and decrementing it from a service handler on CREATE and UPDATE of high-urgency incidents. Shows the resulting metric in SAP Cloud Logging's Discover and Visualize screens, building a custom visualisation from the exported metrics data.gopalanand, published 2024-06-27
