It looks like SigNoz otel collector is down. Could you please share SigNoz OtelCollector logs?

I assume you're referring to the platform my-release-signoz-otel-collector? The pod is running: kubectl -n platform get pods NAME READY STATUS RESTARTS AGE clickhouse-operator-8cff468-f2hm8 2/2 Running 0 15d my-release-zookeeper-0 1/1 Running 0 15d chi-signoz-cluster-0-0-0 1/1 Running 0 15d my-release-signoz-query-service-0 1/1 Running 0 15d my-release-signoz-alertmanager-0 1/1 Running 0 15d my-release-signoz-frontend-6b7dbccbc7-fgbnv 1/1 Running 0 15d my-release-signoz-otel-collector-metrics-68bcfd5556-7tjks 1/1 Running 0 15d my-release-signoz-otel-collector-66c8c7dc9d-xqxbd 1/1 Running 0 15d Quite a few of these errors in my-release-signoz-otel-collector-66c8c7dc9d-xqxbd: time="2022-06-10T203203Z" level=error msg="dial tcp: i/o timeout" component=clickhouse time="2022-06-10T203208Z" level=error msg="dial tcp: i/o timeout" component=clickhouse 2022-06-10T203210.871Z info exporterhelper/queued_retry.go:215 Exporting failed.

@Chris Ahern clickhouse pod is up and running and other pods ready.. So, it means it was accessible and healthy at one stage. Clickhouse pod logs would have helped to debug it better. Please do let me know if this issue still persists or already resolved.

I've since upgrades signoz to 0.9.2. Now either of these are working (I regenerated the json for each node). Any pointers? What do the uid's in the json refer to?

@Chris Ahern not clear what do you mean. are you able to see data in the above dashboard correctly?

@Chris Ahern Did you follow the upgrade guide from our website? https://signoz.io/docs/operate/kubernetes/#upgrade

I ran the helm upgrade command, primarily based on the version specification in https://signoz.io/docs/install/kubernetes/others/.

That part of the docs is actually little old, which needs to be updated.

ok, thx. I'm seeing this: helm search repo signoz --versions NAME CHART VERSION APP VERSION DESCRIPTION signoz/signoz 0.0.13 0.8.0 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.12 0.7.5 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.11 0.7.4 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.10 0.7.1 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.9 0.7.1 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.8 0.6.2 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.7 0.6.1 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.6 0.6.1 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.5 0.6.0 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.4 0.5.4 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.3 0.5.4 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.2 0.5.4 SigNoz Observability Platform Helm Chart signoz/alertmanager 0.5.2 0.5.0 The Alertmanager handles alerts for SigNoz. signoz/alertmanager 0.5.1 0.5.0 The Alertmanager handles alerts for SigNoz. signoz/alertmanager 0.5.0 0.5.0 The Alertmanager handles alerts for SigNoz. signoz/clickhouse 16.0.5 21.12.3.32 A Helm chart for ClickHouse signoz/clickhouse 16.0.4 21.12.3.32 A Helm chart for ClickHouse signoz/clickhouse 16.0.3 21.12.3.32 A Helm chart for ClickHouse signoz/clickhouse 16.0.2 21.12.3.32 A Helm chart for ClickHouse signoz/clickhouse 16.0.1 21.12.3.32 A Helm chart for ClickHouse signoz/clickhouse 16.0.0 21.12.3.32 A Helm chart for ClickHouse signoz/clickhouse 9.1.0 21.7 A Helm chart for ClickHouse

that's clickhouse charts version.

great - I ran that and see other versions: helm search repo signoz --versions NAME CHART VERSION APP VERSION DESCRIPTION signoz/signoz 0.2.5 0.10.2 SigNoz Observability Platform Helm Chart signoz/signoz 0.2.4 0.10.1 SigNoz Observability Platform Helm Chart signoz/signoz 0.2.3 0.10.1 SigNoz Observability Platform Helm Chart signoz/signoz 0.2.2 0.10.0 SigNoz Observability Platform Helm Chart signoz/signoz 0.2.1 0.10.0 SigNoz Observability Platform Helm Chart signoz/signoz 0.2.0 0.10.0 SigNoz Observability Platform Helm Chart signoz/signoz 0.1.4 0.9.2 SigNoz Observability Platform Helm Chart signoz/signoz 0.1.3 0.9.2 SigNoz Observability Platform Helm Chart signoz/signoz 0.1.2 0.9.2 SigNoz Observability Platform Helm Chart signoz/signoz 0.1.1 0.9.1 SigNoz Observability Platform Helm Chart signoz/signoz 0.1.0 0.9.0 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.20 0.8.2 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.19 0.8.2 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.18 0.8.2 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.17 0.8.1 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.16 0.8.0 SigNoz Observability Platform Helm Chart signoz/signoz 0.0.15 0.8.0 SigNoz Observability Platform Helm Chart

signoz/signoz

0.2.5

I ran the upgrade to 0.2.5 and got the following: helm -n platform upgrade my-release signoz/signoz --version 0.2.5 Release "my-release" has been upgraded. Happy Helming! NAME: my-release LAST DEPLOYED: Mon Aug 22 105304 2022 NAMESPACE: platform STATUS: deployed REVISION: 7 NOTES: 1. You have just deployed SigNoz cluster: - frontend version: '0.9.2' - query-service version: '0.9.2' - alertmanager version: '0.23.0-0.2' - otel-collector version: '0.45.1-1.3' - otel-collector-metrics version: '0.45.1-1.3'

which version of signoz were you using prior? 🤔

Was on 0.8.0. Thx - I'll take a look at that. The kubernetes dashboards are showing data now.
