New O'Reilly Book, Anomaly Detection For Monitoring

Together with Preetam Jinka, I’m writing a book for O’Reilly called Anomaly Detection for Monitoring (working title).

I’d like your help with this. Would you please comment, tweet, or email me examples of anomaly detection used for monitoring; and monitoring problems that frustrate you, which you think anomaly detection might help solve?

Thanks in advance.
