Debug Logs are one of the most powerful troubleshooting and monitoring tools in Salesforce. Understanding Debug Logs helps Salesforce developers identify errors, analyze execution flow, monitor system behavior, troubleshoot integrations, optimize performance, and validate business processes.
Whenever Apex code, Flows, Triggers, Validation Rules, APIs, or user actions execute within Salesforce, the platform can generate Debug Logs that record detailed information about what happened during execution. These logs help developers understand why errors occur and how applications behave.
Mastering Debug Logs is essential for Salesforce development, testing, deployment, and production support.
Debug Logs are detailed records of system activity generated during Salesforce execution.
Debug Logs capture:
They help developers troubleshoot issues.
