Deploy this integration to send traces from your Istio service mesh layers to Logz.io via the OpenTelemetry collector using logzio-otel-traces Helm chart. The main repository for Logz.io helm charts are logzio-helm.

Before you begin, you’ll need:

  • An applicaion instrumented by Istio in a Kubernetes cluster
  • Istioctl installed on your machine
  • An active account with Logz.io

Configuration instructions

Deploy the Helm chart in the same Kubernetes cluster as your application

Add logzio-helm repo as follows:

helm repo add logzio-helm https://logzio.github.io/logzio-helm
helm repo update
Run the Helm deployment code
helm install  \
--set config.exporters.logzio.region=<<LOGZIO_ACCOUNT_REGION_CODE>> \
--set config.exporters.logzio.account_token=<<TRACING-SHIPPING-TOKEN>> \
logzio-otel-traces logzio-helm/logzio-otel-traces

Replace <<TRACING-SHIPPING-TOKEN>> with the token of the account you want to ship to.

If your account is hosted in any region other than us, replace <LOGZIO_ACCOUNT_REGION_CODE> with the applicable region code.

If your account is hosted in us, remove region: line from the config.

Define the logzio-otel-traces service name

In most cases, the service name will be logzio-otel-traces.default.svc.cluster.local, where default is the namespace where you deployed the helm chart and svc.cluster.name is your cluster domain name.

If you are not sure what your cluster domain name is, you can run the following command to look it up:

kubectl run -it --image=k8s.gcr.io/e2e-test-images/jessie-dnsutils:1.3 --restart=Never shell -- \
sh -c 'nslookup kubernetes.default | grep Name | sed "s/Name:\skubernetes.default//"'

It will deploy a small pod that extracts your cluster domain name from your Kubernetes environment. You can remove this pod after it has returned the cluster domain name.

Set Istio to send traces to Logz.io

Replace <<logzio-otel-traces-service-name>> in the command below with the service name obtained in the previous step and run the command.

istioctl install --set meshConfig.defaultConfig.tracing.zipkin.address=<<logzio-otel-traces-service-name>>:9411 --set values.pilot.traceSampling=100.0

By default, we set the traceSampling to 100, which means that Istio will send 100% of the application traces to Logz.io. You can adjust this value as required.

Check Logz.io for your traces

Give your traces some time to get from your system to ours, then open Logz.io.
