How to debug gobi?
I've encountered some errors but don't know how to debug Gobi, can you provide any advice?

What is mean the labelset
The project is so cool!
# Supported flows aggregation labels (default: SamplerAddress)
labelset: ["Type", "FlowDirection", "SamplerAddress", "SrcAddr",
"DstAddr", "Etype", "Proto", "SrcPort", "DstPort",
"InIf", "OutIf", "SrcAS", "DstAS", "NextHop", "NextHopAS",
"SrcNet", "DstNet", "SrcCountry", "DstCountry"]
My flow record:
Flow Record:
Flags = 0x06 NETFLOW v9, Unsampled
label = <none>
export sysid = 1
size = 68
first = 1681290659 [2023-04-12 17:10:59]
last = 1681290719 [2023-04-12 17:11:59]
msec_first = 168
msec_last = 896
src addr = 192.168.122.1
dst addr = 192.168.122.26
src port = 161
dst port = 161
fwd status = 0
tcp flags = 0x00 ........
proto = 17 UDP
(src)tos = 0
(in)packets = 501
(in)bytes = 81420
input = 1
output = 0
src as = 0
dst as = 0
How to mapping them?
I should config "labelset" as below?
labelset: ["src as", "dst as", "src port", "dst port", ... ...]
Please help :)
An option to preserve port numbers in metrics
Is there any way to keep port numbers in metrics instead of converting them to service names (which seems to happen by default)? This would allow aggregation of flows received from exporters that doesn't support bidirectional flows, as well as gathering information based on custom port numbers.
Data ingestion on stdin
Compared to similar projects based on goflow2, gobi looks interesting, however so far I've encountered at least one major issue.
Data ingestion seems to work when provided through goflow2 transport file (despite continuous "proto: cannot parse invalid wire-format data \ unexpected EOF" warnings). I cannot make it work, however, with netflow data provided through pipe. Or have I understood something inherently wrong (unfortunately, documentation is scarce)? For the clarity sake, I'm not using any container system and what I'm trying to do is simple: goflow2 -format pb [...] -transport.file "" | gobi -f gobi.yml.
