Drone, Equivalent, Fiber, Gossip, Identification
This lesson introduces the following analysis patterns: drone message, equivalent messages, fiber bundle, gossip, and identification messages.
We'll cover the following...
Drone message
Sometimes we see a constantly repeated message throughout a trace or log (a trivial periodic message block) with a 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 an analogy with the drone effect in music.
Equivalent messages
Some trace and log messages may have different grammatical structures and content but similar semantics. Therefore, we can create a table listing equivalent messages (using some equivalence relation) and use it to construct simpler traces and logs ...
