The logfiles on your servers should be verbose enough to indicate what
machines are handling which parts of the request.
Yes, generally i see the following entries in logs:
1.
df=_text_&distrib=false&fl=_id&fl=score&shards.purpose=4&start=0&fsv=true&sort=<sort
expression>fq=<fq expression>&shard.url=<shard IP and
path>&rows=24&version=2&q=<q
expression>&NOW=1540984948280&isShard=true&wt=javabin
2. df=_text_&distrib=false&fl=<full list of
fields>&shards.purpose=64&start=0&fq=<fq
expression>&shard.url=<shard IP and path>&rows=24&version=2&q=<q
expression>&NOW=1540984948280&ids=<list of IDs>&isShard=true&wt=javabin
3. q=<q expression>&fl=<full list of fields>&start=0&sort=<sort
expression>&fq=<fq expression>&rows=24&version=2.2&wt=json
Request type #3 (full request) is seen only 1 time across all shards,
and I suppose it is the original/aggregated request. The shard is
different every time, so this means load balancing is working.
Request #1 (get IDs by query) is always present for one replica of each
shard.
Request #2 (get fields by IDs) is, however, sometimes missing even
though request #1 has a non-zero number of hits for that shard. But i
don't know if this could indicate a problem or it is working as expected?
Only one attachment made it to the list. I'm surprised that ANY of
them made it -- usually they don't. Generally you need to use a file
sharing website and provide links. Dropbox is one site that works
well. Gist might also work.
The GC log that made it through (solr_gc.log.7.1) is only two minutes
long. Nothing useful can be learned from a log that short. It is
also missing the information at the top about the JVM that created it,
so I'm wondering if you edited the file so it was shorter before
including it.
Thanks,

You are right, sorry, i didn't know this :)
(there is a 1MB limitation on attachments which is why i trimmed the log)
Here are the full GC logs: 1
