You are reviewing log files that can be accessed in Appian to monitor and troubleshoot...

design_errors.csv → Errors in start forms, task forms, record lists, enabled environments

devops_infrastructure.csv → Metrics such as the total time spent evaluating a plug-in function

login-audit.csv → Inbound requests using HTTP basic authentication

Comprehensive and Detailed In-Depth Explanation:

Appian provides various log files to monitor and troubleshoot platform issues, accessible through the Administration Console or exported as CSV files. These logs capture different aspects of system performance, security, and user interactions. The Appian Monitoring and Troubleshooting Guide details the purpose of each log file, enabling accurate matching.

design_errors.csv → Errors in start forms, task forms, record lists, enabled environments:The design_errors.csv log file is specifically designed to track errors related to the design and runtime behavior of Appian objects such as start forms, task forms, and record lists. It also includes information about issues in enabled environments, making it the appropriate match. This log helps developers identify and resolve UI or configuration errors, aligning with its purpose of capturing design-time and runtime issues.

devops_infrastructure.csv → Metrics such as the total time spent evaluating a plug-in function:The devops_infrastructure.csv log file provides infrastructure and performance metrics for Appian Cloud instances. It includes data on system performance, such as the time spent evaluating plug-in functions, which is critical for optimizing custom integrations. This matches the description, as it focuses on operational metrics rather than errors or security events, consistent with Appian’s infrastructure monitoring approach.

login-audit.csv → Inbound requests using HTTP basic authentication:The login-audit.csv log file tracks user authentication and login activities, including details about inbound requests using HTTP basic authentication. This log is used to monitor security events, such as successful and failed login attempts, making it the best fit for this description. Appian’s security logging emphasizes audit trails for authentication, aligning with this use case.

Unused Description:

Number of enabled environments: This description is not matched to any log file. While it could theoretically relate to system configuration logs, none of the listed files (design_errors.csv, devops_infrastructure.csv, login-audit.csv) are specifically designed to report the number of enabled environments. This might be tracked in a separate administrative report or configuration log not listed here.

Matching Rationale:

Each description is either used once or not at all, as specified. The matches are based on Appian’s documented log file purposes: design_errors.csv for design-related errors, devops_infrastructure.csv for performance metrics, and login-audit.csv for authentication details.

The unused description suggests the question allows for some descriptions to remain unmatched, reflecting real-world variability in log file content.
