ubuchk helps manage system alerts and configurations. Each alert is identified by a unique 4-character ID. Administrators can query these IDs to understand specific system warnings or errors. The tool allows for fine-grained control over which checks are performed and how their results are reported. By overriding key values or skipping specific alerts, users can tailor the health check process to their specific needs, ensuring that only relevant issues are flagged and addressed.
