Example 1: Storage Performance Machine Learning Method Selection of Right Data Set Quality Check of Data Analysis of the Data Insight Generation Data Pattern Matching Models: MultiVariate Regression Analysis (Causal) Time Series Analysis Final: Multivariate Time Series (VAR Model) Features: Total IOPS Cache Hit Ratio (%) Disk Response Time Disk Utilization Prediction: Average Response Time (Latency) Similarly for- Capacity CPU Failure Disk Failure [%age Write Miss Data Transfer Rate (MB/s) No.of Active Network Ports Spindle Count RAID Configuration Disk Type] 8

Example 2: Prediction of Database Response Time Business Problem Solution To predict the database response time and facing challenges as below To create predictive models which predict DB response time. To predict 1-hour-later SLA violation of DB response time with 90% of recall and 70% of precision. The predictive models predict the Probabilistic distribution of DB response time at the time of 1hour later. Creation of Lab environment to load on DB and measurement of various parameters for model building Predictive models to: Predict number of queries on the DB after 1 hour DB response time after 1 hour To identify load on the system after 1 hour and corrective action planning Techniques - Unobserved component models and Poisson Regression Benefits All models are having Mean Absolute Percentage Error (MAPE) less than 5% Precision & recall rate for 1 hour later prediction was 60% and 45% respectively. 9
