Performance tests can be used to examine and analyze the behavior of any service mesh you choose to deploy.

Install your service mesh

Meshery allows for easy, one-click installations. Follow the steps below to install atleast two service meshes to run performance tests on:

1. Select the service mesh you wish to deploy from the Management menu

2. Navigate to the service mesh's management page:

For the purpose of this session, we will be working with Istio and Linkerd. However, you can perform the session with any service meshes you choose.

Note : If you are using other service meshes, any changes to the steps (if required) will be highlighted in the session instructions.

• Type default into the namespace field
• Click the (+) icon on the Install card and select the latest version to install

Check for successful installation

The service mesh has been deployed in the default namespace. You will now be able to see the successful deployment status of the service meshes you have installed on your Meshery dashboard:

You may also manually run the following command from the terminal to check for successful configurations:

kubectl get all -n <namespace>

Note : You can paste in the command in the terminal with Shift + Insert and switch the namespace with respect to the service mesh you wish to check for.

For the purpose of this tutorial session, we will be deploying the Bookinfo sample app with Istio and the Emojivoto sample app with Linkerd.

Istio

Deploy the Istio Bookinfo Sample App

1. Click on (+) under Apply Service Mesh Configuration
2. Choose Automatic Sidecar Injection
3. Check if istio-injection has been enabled for your namespace: kubectl get namespace -L istio-injection
4. Select the Bookinfo application in the Sample Application drop down menu. This will install the Bookinfo sample app under the default namespace.
5. Verify that the deployments are all in a state of AVAILABLE before continuing. watch kubectl get deployment
6. Expose the Ingress gateway by running: kubectl get svc istio-ingressgateway -n istio-system -o yaml
7. Click on (+), next to the Meshery Server tab. Choose Open New Terminal and run: minikube tunnel
8. Access the external port of the Ingress pod by running: kubectl get service istio-ingressgateway -n istio-system -o wide
9. To print out the first port on your terminal, run: kubectl get service istio-ingressgateway -n istio-system --template='{{(index .spec.ports 1).nodePort}}'
10. Click on icon, next to the Meshery Server tab
11. Enter the port number before clicking on Display Port.
12. To view the product page, append /productpage to the url of the page.

You should now be able to see the BookInfo dashboard on the screen.

Linkerd

Deply the Linkerd EMojivoto Sample App

1. Verify the status of your proxy injector by running: kubectl get deployment linkerd-proxy-injector -n linkerd-system
2. Navigate to the Linkerd Management page on the Meshery dashboard.
3. Select Emojivoto Application from the list of available Sample Applications.
4. Verify succesfful deployment: watch kubectl get deployment -n default
5. Verify that all the deployments are READY before continuing. watch kubectl get po -n default
6. You may view the sidecar configurations of any of Emojivoto's services: kubectl get svc -n default kubectl describe svc/web-svc -n default
7. Assess the application deployment by port-forwarding the web-svc service: kubectl port-forward svc/web-svc 80:80 --address 0.0.0.0 -n default
8. Click on icon, next to the Meshery Server tab
9. Enter the port number: 80 before clicking on Display Port.

You should now be able to access the Emojivoto dashboard.

Meshery allows you to run performance tests directly from your dashboard.

Go to Performance

The Performance test asks for the following inputs:

• Test Name: Enter any test name that you wish. If you do not provide one, a random name will be generated for you.

• Service Mesh: Choose the service mesh you wish to run the performance test on. For this session, choose either Istio or OSM.

• URL to test: Enter the URL of the page you wish to run the test on. For Istio, paste in the URL of the BookInfo productpage dashboard deployed in the last step.

• Concurrent Requests: Enter a valid number for Concurrent Requests

• Queries per second: Enter a valid number for Queries per second

• Duration: Type in the duration for which you want to tes

• Load generator: Choose the Load generator you wish to base the test on. Meshery supports fortio, wrk2, and Nighthawk.

Click on **Run Test**.

To be able to compare, repeat the same test for Linkerd by pasting in the URL of the Emojivoto dashboard. We have already deployed the app in last step. It should now be running on port 80.

When you run a performance test has been executed, Meshery performs a disco analysis and persists the test results. The results are available in the Service Mesh Performance (SMP) format.

Go to Performance > Results on your Meshery dashboard.
