Pages of generic tracing text may give you enough information for
exploring a system. With systemtap, it is possible to analyze that
data, to filter, aggregate, transform, and summarize it. Different
probes can work together to share data. Probe handlers can use a rich
set of control constructs to describe algorithms, with a syntax taken
roughly from awk. With these tools, systemtap scripts can
focus on a specific question and provide a compact response: no
grep needed.
