Hi guys. I have deployed Signoz to Kubernetes and I have run into signoz-schema-migrator-sync-init-8nqkq pod error

{"L":"info","timestamp":"2024-12-03T21:24:16.080Z","C":"schema_migrator/manager.go:395","M":"Mutation details","database":"signoz_logs","table":"schema_migrations_v2","command":"UPDATE status = 'failed', error = 'failed to wait for mutations\\nbackoff stopped', updated_at = '2024-12-03 21:14:50' WHERE migration_id = 1","mutation_id":"0000000007","latest_fail_reason":"Code: 198. DB::NetException: Not found address of host: core2-clicksignoz-prod-n2. (DNS_ERROR) (version 24.11.1.2557 (official build))"}

I see that it tries to connect to

core2-clicksignoz-prod-n2

. It is a hostname of one of external clickhouse nodes, BUT I defined IP address in helm chart.

...
spec:
  containers:
  - args:
    - sync
    - --dsn
    - tcp://$(CLICKHOUSE_USER):$(CLICKHOUSE_PASSWORD)@10.xx.x.220:9001
    - --replication
    - --up=
    env:
    - name: CLICKHOUSE_HOST
      value: 10.xx.x.220
    - name: CLICKHOUSE_PORT
      value: "9001"
    - name: CLICKHOUSE_HTTP_PORT
      value: "8124"
    - name: CLICKHOUSE_CLUSTER
      value: cluster
...

How to resolve this problem? Thank you in advance

Hi there! new signoz user (trying it out to replace some legacy apps)... currently have it up and running all reports ok... trying to deploy the docker-compose agent (self hosted).. the troubleshoot docker image runs and sends data to the host... but the infra monitoring view remains empty... also logs.. from the infra monitor on the host running signoz has halted.. any input or tips would be appreciated

i tried signoz distributed clickhouse, migration (sync and async) success. but there are some missing tables inside clickhouse-2 and clickhouse-3...for example signoz_metrics.samples_v4 missing on clickhouse-2 clickhouse-3.

Hey team. We're in the process of evaluating SigNoz. I was attempting to get it spun up on a Talos K8 cluster, but am not getting any kubernetes/pods metrics. Just installing a fresh

signoz/signoz

at

0.50.0

helm chart with default values sets everything up properly, no errors, but I am not getting any Kubernetes metrics out of the box. I read the documentation at https://signoz.io/docs/install/kubernetes/others/ and it stated the k8s-infra chart should be included, but as of https://github.com/SigNoz/charts/commit/a99b93fbc32801eca528e9046eddcc68a625d5ae, it appeared to be removed as a dependency. I deployed the

k8s-infra

helm chart with default values and still no cigar. I don't see any errors on any of these pods logs, storage is provisioned correctly. It appears

k8s-infra

is collecting metrics looking at the logs. Took a look at the support channel and found https://signoz-community.slack.com/archives/C01HWQ1R0BC/p1723457860195989. I confirmed that if I delete the collector service, I am getting a TCP dial failure in the agent logs for the insecure port, so the configuration seems to be correct for this case. Looking for a gentle nudge in the right direction if possible, thanks for your time!
