Hands-On Video Tutorials – Part III

Philip MUGGLESTONE just updated his developer onboarding video tutorial series for the SAP Cloud Platform. In this blog, you will find the videos embedded with some additional information and resources. Following along in the patented zero-to-hero format, no prior knowledge required, you will be ready to start developing business applications on the platform with minimal effort and no time wasted.

You can watch the two video tutorials in about twenty minutes. What you learn is

• How to view standard application logs
• How to work with the Application Logging service and the Kibana dashboard
• How to integrate application logging into your application
• How to view standard audit logs
• How to work with the Auditlog Management service
• How to integrate audit logging into your application

To bookmark the playlist on YouTube, go to

Application Logging

In this video tutorial, see how to create, access and analyze application-related logs, container metrics and custom metrics in the Cloud Foundry environment. Philip shows how to access the Cloud Foundry application logging service and connect it to a running application before showing how to incorporate application logging into a multi-target application that also includes custom metrics.

Audit Logging

In this video tutorial, see how to access audit logs created in the Cloud Foundry environment. While the consumer of application logs is often a system administrator who would like to keep track of the state of a system, audit logs are read by an auditor. There are legal requirements (in some countries stricter than in others) regarding audit logging. Philip shows how to access the Cloud Foundry audit logging viewer application and how to access audit logs via the REST API using Postman and also a custom Node.js microservice.
