1. A computer-implemented method for checking health of information technology infrastructure based on log data, comprising:

  • collecting log data non-intrusively from a production system, said log data at least associated with transactions occurring in the production system and resource utilization of the production system;

    normalizing said log data into a plurality of log data types;

    performing data regression analysis using said plurality of log data types to estimate resources consumed by each of said transactions and throughput of each of said transactions, the data regression analysis including solving a least square problem of linear regression between the observed request throughput and resource utilization level;

    using a queuing model based on the estimated resources consumed and the estimated throughput to predict performance of the information technology infrastructure under a plurality of workloads; and

    identifying one or more potential performance issues and recommending solutions.
