Anyone know how to troublsehoot connection between collector and clickhouse on a cluster? We are seeing the traces go through the collector using logs, but then we dont see them in traces…. we are looking in the signoz_traces database, signoz_span table

That sounds like unexpected behaviour. @Itay Baror we could perhaps get on quick call to resolve this.
It could be caused by issue with clickhouse not being healthy or storage being full.
