Split, Tensor, Dimension, Extension, Homotopy
Explore key software trace analysis patterns including split traces, tensor traces, trace dimensions, trace extensions, and trace homotopy. Understand how to manage complex logs from distributed environments, combine multiple traces, simplify trace data, and compare software execution changes. This lesson equips you with methods to enhance troubleshooting and root cause analysis in varied software contexts.
We'll cover the following...
Split trace
Some tracing tools can split software traces and logs into several files during long recording. Although this should be done judiciously, it is sometimes necessary. What do we do if we get several trace files and use other analysis tools that cannot do that? If we know that the problem happened just before the tracing was stopped, we can look at the last few files from the file sequence (although we recommend circular trace here). Otherwise, we can convert them into CVS files and import them into Excel, which also supports adjoint threading.
Tensor trace
We first thought of the tensor trace analysis pattern in the context of memory dumps as general traces with several special traces inside. This developed further while we were working on singleton trace analysis pattern when we realized that several singleton traces can form a new separate log.
Thus, we realized we may combine several traces and logs into one global trace where each message references separate local traces and logs.
A typical example is repeated tracing. Each trace has an i-th index spanning the number of trace ...
