grafana/loki-stack how can i add grafana tempo

Question

I'm trying to customize the trace display using Grafana Tempo. I use helm grafana/loki-stack https://grafana.com/docs/loki/latest/installation/helm/. Installing command helm upgrade --install loki grafana/loki-stack --set grafana.enabled=true,prometheus.enabled=true,prometheus.alertmanager.persistentVolume.enabled=false,prometheus.server.persistentVolume.enabled=false,loki.persistence.enabled=true,loki.persistence.storageClassName=managed-premium,loki.persistence.size=250Gi -n logs

But when I add the setting tempo.enabled=true nothing happens. Could you please tell me how can I add tempo when deploying this stack? Or how can I add it? Thanks.

Answer 1

Simply put, you've made an assertion that if you can 'enable' Prometheus, you can simply 'enable' Tempo.

If you have a look at the corresponding Helm directory for loki-stack you can see that Tempo is not in the values.yaml unfortunately. (At this point in time)

https://github.com/grafana/helm-charts/blob/5b2dacdfe93fa306d83302455890b9deb7f814a0/charts/loki-stack/values.yaml

To add it you would need to create and maintain your own Helm chart for loki-stack with Tempo.
