Hi 👋 , in signoz helm chart I use externalClickhouse with a different cluster name than 'cluster' CLICKHOUSE_CLUSTER is set correctly as env var but otel collectors fail to take it:
message: Requested cluster 'cluster' not found
do you confirm it's not possible to use the helm value externalClickhouse.cluster at the moment ?

Hi @Pierre 👋 custom cluster name is not supported at the moment by SigNoz.
In case you use external clickhouse, you must have a cluster named
cluster
as mentioned in the external clickhouse prerequisites. https://signoz.io/docs/operate/clickhouse/external-clickhouse/#prerequisites
