This paper designs exception monitoring model for Linux system.The Warn Notify(WN) protocol is designed for the model.When an exception occurs,the adoption of the protocol can be alarm information to be passed to other multiple hosts.Model uses Principal Component Analysis(PCA) combined with Hotelling's statistics and Q statistic for anomaly detection.After an exception occurs,the contribution plots getting by principal component method is used to target a specific detection point.Experimental results show that the model has high abnormal monitoring accuracy.
