Excessive logging

Excessive logging occurs when an application logs too much information, often at overly verbose or unnecessary levels like debug, producing large volumes of logs that obscure important messages. This log spam can degrade application performance, complicate log analysis, and increase storage and processing costs. Typically, excessive logging results from improper log-level configuration, debugging statements left in production, or overly granular logging practices.

To fix excessive logging, carefully configure log levels (such as ERROR, WARN, INFO, DEBUG) to ensure only meaningful, context-appropriate information is recorded in production environments. Remove or refactor verbose debug statements after resolving issues, reducing unnecessary log output. Implement log rotation, structured logging, or sampling techniques to manage log volume effectively. Regularly review and audit logging practices, balancing the need for debugging information with performance considerations and readability, ensuring logs remain useful and manageable.
