| // The generic failure collector collects issues that anomaly_detector catches |
| // that manifest as a single line logged to a log file. |
| // The flow looks like this: |
| // 1. One of the parsers in anomaly_detector flag an issue |
| // 2. anomaly_detector invokes crash_reporter with an appropriate flag |
| // 3. crash_reporter invokes a GenericFailureCollector instance |
