Provide clarification on the field component_name.

[morrowc]

Might wait on heas@ to have a look at this.

LGTM. I would add another eg for clarity; eg: component_name: chassis0/linecard0

LGTM. I would add another eg for clarity; eg: component_name: chassis0/linecard0

Added another example as suggested

Can you elaborate a bit on how it is supposed to be used / what is the purpose of the field? In what cases, for example, linecard0 component is used?

I would imagine that in most cases, accounting records are generated by control modules (in chassis-based systems) or a control module equivalent in a fixed system. Does it mean that the chassis returns the name of the active control module (at the time when the record was created)?

This is field is useful in a system where multiple entities can generate accounting records. For example, modular systems where we can have multiple control modules, each in active/standby roles. An accounting event can happen on any component resulting in a RecordResponse message. This fields can identify from which component a RecordResponse originated from.

Yeah, it is more or less clear with the control modules.
What would constitute an accounting event on a line card? Is it for systems that allow users to directly connect to each line card (e.g. the linecard has a management IP, etc)?

[haussli]

Some systems have redundant routing engines, multiple chassis with their own routing engines/control cards, and some have a linecards/cards in general that have a cli accessible in-line or from a serial port. It is reasonable to expect that these cards might log/account these activites. This field allows the origin or the records to be identified, which I would expect to be platform/vendor specific. eg: (WAGs)
fpc0
chassis1/fpc0
re0
re1
chassis1/re1
0/RP0/CPU0
