Trace Analysis Patterns (Part 196)

Friday, July 31st, 2020

It is possible to foliate traces into separate traces having the same structure and scale (we also show corresponding Trace Fabric for the original trace):

In the diagram above Trace Foliation was done for message type, for example, error and normal messages. The reverse operation of Trace Mask would produce the same original trace.

Correspondingly Trace Fabric can be foliated too giving rise to “orchestra” representation and vice versa via Trace Mask:

Bars can be added with the help of Silent Messages.

The name of this analysis pattern was also inspired by foliations in mathematics.

Trace Analysis Patterns (Part 194)

If we take Combed Trace for Thread of Activity or some Adjoint Thread of Activity and strip other message content like we did for Trace Contour log analysis pattern we get individual braids that form Trace Fabric:

We can also get a stave representation of individual braids after a counter clockwise 90 degree rotation:

Bars can be added with the help of Silent Messages. Conversely, a musical piece can be transformed into some trace.

We mentioned “fabric” metaphor already when we introduced multibraiding.

Trace Analysis Patterns (Part 167)

Sometimes we see a constantly repeated message throughout a trace or log (a trivial Periodic Message Block) with constant Time Delta. In certain trace forms (without explicit timing information) such messages may indicate internal time references as illustrated in the following diagram:

We name this pattern Drone Message based on analogy with Drone effect in music.
