abstract = "Fault-detection approaches in autonomic systems
typically rely on runtime software sensors to compute
metrics for CPU load, memory usage, network throughput,
and so on. One detection approach uses data collected
by the run time sensors to construct a convex-hull
geometric object whose interior represents the normal
execution of the monitored application. The approach
detects faults by classifying the current application
state as being either inside or outside of the convex
hull. However, due to the computational complexity of
creating a convex hull in multi-dimensional space, the
convex-hull approach is limited to a few metrics.
Therefore, not all sensors can be used to detect faults
and so some must be dropped or combined with
others.
This paper compares the effectiveness of genetic-programming, genetic-algorithm, and random-search approaches in solving the problem of selecting sensors and combining them into metrics. These techniques are used to find 8 metrics that are derived from a set of 21 available sensors. The metrics are used to detect faults during the execution of a Java-based HTTP web server. The results of the search techniques are compared to two hand-crafted solutions specified by experts.",
