Hey, I see cluster is hardcoded atm <https://github.com/SigNoz/signoz-otel-collector/blame/main/exporter/clickhousemetricsexporter/clickhouse.go#L47>
Setting env `CLICKHOUSE_CLUSTER` doesn't have any effect as it is not read by collector, and hence you're facing the problem

To make it work, use `cluster` for your clickhouse cluster name.

I can see that. But I need to use multi signoz, that mean I need to create multi clickhouse “cluster”. It is so crazy,
My expect is signoz of A team use clickhouse cluster A and signoz of B team use clickhouse cluster B. Then I can operate all clickhouse cluster easier.
An other solution is change database name of signoz. But I see it is hardcoded with `signoz-logs` database as this issues:
