Hi all 🙂 I'm in need of help, I'm trying to run Signoz on an Azure AKS cluster with an external clickhouse database. Everything seems to startup, but otel-collector and otel-collector-metrics throws an error

error connecting to primary db: code: 170, message: Requested cluster 'cluster' not found

I've set the

clusterName

and the

global.clusterName

. Most other settings are default.

CLICKHOUSE_CLUSTER : signoz
CLICKHOUSE_DATABASE : signoz_metrics
CLICKHOUSE_HOST : *redacted*
CLICKHOUSE_HTTP_PORT : 8123
CLICKHOUSE_PASSWORD : *redacted*
CLICKHOUSE_PORT : 9000
CLICKHOUSE_SECURE : false
CLICKHOUSE_TRACE_DATABASE : signoz_traces
CLICKHOUSE_USER : admin
CLICKHOUSE_VERIFY : false
K8S_CLUSTER_NAME : dev-monitoring-aks
K8S_NAMESPACE : fieldRef(v1:metadata.namespace)
K8S_NODE_NAME : fieldRef(v1:spec.nodeName)
K8S_POD_IP : fieldRef(v1:status.podIP)
K8S_POD_NAME : fieldRef(v1:metadata.name)
K8S_POD_UID : fieldRef(v1:metadata.uid)
LOW_CARDINAL_EXCEPTION_GROUPING : false
OTEL_RESOURCE_ATTRIBUTES : host.name=$(K8S_NODE_NAME),signoz.component=$(SIGNOZ_COMPONENT),k8s.cluster.name=$(K8S_CLUSTER_NAME),k8s.pod.uid=$(K8S_POD_UID),k8s.pod.ip=$(K8S_POD_IP)
SIGNOZ_COMPONENT : otel-collector

Above are the env vars for the pod. The init container connects fine to the database and reports

clickhouse ready, starting otel collector now

. I'm using latest helm chart. Am I doing something wrong or missing some configuration?

In case you would like to use external ClickHouse DB, you would have to follow additional steps. • at least one instance of zookeeper • create cluster configuration along with zookeeper remote server • copy

custom-scripts.xml

as well as binary inside

user-scripts

folder • make sure user credentials passed has enough privileges to create/access databases ^ For all these, you can refer here: https://github.com/SigNoz/signoz/tree/develop/deploy/docker/clickhouse-setup cc @Ankit Nayan
