The node errors as implemented in src/vlib/error.[ch] came first.
The stats segment is just a representation of these per-node counters. The
stats segment is essentially a KV store,
where the node counters are given a key as
"/err/<node-name>/<error-counter-name>
You are absoultely right that some nodes do use this counter infrastructure for
non-error situations.
e.g. we have "no error", "encapsulated", "decapsulated" by some nodes and so on.
I at some point was thinking of placing these under a different path. Then I
distracted myself by thinking of how all the counters could be represented in a
data model instead (specifically a YANG tree).
Cheers,
Ole
