Use Case 01 The result of root causes of a failure

Root Cause of Problems

※ CPU overload and frequent memory increase and decrease during memory swapping in Oracle DB and subsequent DB failures.

Problems Predictions & Result

※ Predicts memory swapping related occurrences on the device.

※ Memory swapping symptoms occurred as PETAON Forecaster had predicted, resulting in continuous CPU load increase.
    and frequent memory increase and decrease.

※ Operated service continuously without failure prevention activities.

※ CPU overload and memory anomalies occurred.

※ Predicted service failure occurred (23:01:10 ~ 23:06:40).

Use Case 02 Log Analysis Prediction Result

Predicted abnormal symptoms actually occurred.
Predicted memory swapping actually occurred.

※ Predicted abnormal symptoms that would occur in DB Level 2 in 20 minutes.

※ Predicted memory swapping in Oracle DB.

※ 20 minutes later, abnormal symptoms actually occurred in DB Level 2.

※ In Oracle DB, memory swapping occurred.

Forecast of abnormal symptoms in DB & actual occurrences are matched.

Forecast of memory swapping occurrences & actual logs are matched.
