> I first spotted this in 9.3, I've not gone back to check earlier versions, though it is likely to affect them too. When configuring replica placement rules on a standard out of the box deployment and creating a collection, error messages are logged like this:
> {{{{2023-09-27 08:45:58.188 ERROR (OverseerThreadFactory-19-thread-5) [] o.a.s.c.p.i.AttributeFetcherImpl Received unsolicited snitch tag heapUsage from node NodeImpl(localhost:8983_solr)
> 2023-09-27 08:45:58.188 ERROR (OverseerThreadFactory-19-thread-5) [] o.a.s.c.p.i.AttributeFetcherImpl Received unsolicited snitch tag sysLoadAvg from node NodeImpl(localhost:8983_solr)
> 2023-09-27 08:45:58.188 ERROR (OverseerThreadFactory-19-thread-5) [] o.a.s.c.p.i.AttributeFetcherImpl Received unsolicited snitch tag freedisk from node NodeImpl(localhost:8983_solr)
> 2023-09-27 08:45:58.188 ERROR (OverseerThreadFactory-19-thread-5) [] o.a.s.c.p.i.AttributeFetcherImpl Received unsolicited snitch tag totaldisk from node NodeImpl(localhost:8983_solr)}}}}
>
> That error comes from here: [https://github.com/apache/lucene-solr/commit/c7d234cafd37d824ff6642b449d3cb333d1e4a9a#r129141901]
> [~ilan] said "I suspect it was introduced with SOLR-15019 ([commit|https://github.com/apache/lucene-solr/blob/2695624a9f2d11a63f3640dd7f3bb30c2e6f938e/solr/core/src/java/org/apache/solr/cluster/placement/impl/AttributeFetcherImpl.java#L69]) when requested tags were prefixed with sysprop. but returned tags apparently not."
>
> The error is fairly benign, it just pollutes the logs and makes it look like something is wrong but everything else functions correctly (if you aren't trying to configure rules based on those four metrics at least).
