The user's keyword is "asm health checker found 1 new failures". I'll need to cover the different contexts. I'll also search for "ASM Health Checker cPanel" and "ASM Health Checker Oracle". search results show various contexts. I'll structure the article to cover the main interpretations: Oracle ASM, cPanel/WHM, and other possibilities. I'll also include troubleshooting steps and solutions. I'll start by explaining what ASM is and then focus on the health checker failure. I'll cite relevant sources. into a technical alert like "ASM Health Checker found 1 new failures" can be disconcerting, especially if you're not sure what it means or where to start. This message isn't a system crash, but it is a clear signal that a critical part of your infrastructure—likely an Automatic Storage Management (ASM) instance—has detected a problem and requires your attention. Failure to address these issues promptly can lead to serious consequences, including data corruption and database downtime. This article provides a comprehensive breakdown of what the alert means, why it happens, and exactly how to diagnose and fix the problem.
Check for any explicit failure messages. If a rotation fails, the secret might be left with a AWSPENDING label that doesn't match the actual password on the target database, causing dependency checks to fail. Preventive Strategies

I need to cover what it is, causes,
This error indicates that an automated health check—typically executed via an AWS Lambda function, an Amazon Route 53 health check, or a synthetic monitoring tool—attempted to validate the accessibility, rotation status, or integrity of a secret and failed. Direct Root Causes
To minimize the risk of encountering this or similar alerts, implement these best practices:
If critical or mirrored disks drop below the minimum required for the specified redundancy level, ASM drops the group to safeguard data integrity.
