proj field not exclusively projects

[CannonLock]

When I am looking at the reported xrootd_transfer_bytes as aggregated by the director the proj that is reported does not align with the field description in the docs.

I expect:

Client’s User-Agent header when requesting the file. This is used to label the project name that accesses the file.

I get:

Python/3.12 aiohttp/3.9.5
check_http/v2.2 (monitoring-plugins 2.2)
curl/7.76.1
pelican-client/7.9.9 project/LIGO
...

It is not clear to me if I should be doing more parsing or if this field is falsely populated.

==========================================================================

Below I have included the query that revealed that and the proj field values as they currently exist.

Query: sum by (proj) (increase(xrootd_transfer_bytes{type!="write",proj!=""}[1d]))

Result:

@patrickbrophy This is what I was talking about yesterday.

I would like to only populate this field if we know the project and move the other value ( Client version? ) into another tag leaving the proj as null if unknown.
