• Shared the Porch Metrics through Promethus for the following metrics information:

  • Performance Metrics

  • Operation duration tracking

  • Success/failure counting

  • Resource utilization monitoring

  • Error tracking and reporting

• Originally proposed in the Porch group, and still being reviewed: https://github.com/nephio-project/porch/pull/174

• The definition of the metrics are located here: https://github.com/nephio-project/porch/pull/174/files#diff-ac22d73b99f674a38c82d77b48d40051e484429ef62c6ba76008e83bf64653be

Porch Performance Testing Setup Guide

1. Set Up Development Environment

Run the following script to set up the development environment:

https://github.com/nephio-project/porch/blob/main/scripts/setup-dev-env.sh

2. Build and Deploy Porch

Execute the command below to build and deploy Porch in a Kubernetes Kind cluster:

make run-in-kind

Once deployment is complete, you should see the related pods running.

3. Create a Demo Namespace

Create a namespace for the demo setup:

kubectl create namespace porch-demo

4. Set Up Gitea Credentials

Create a secret to store Gitea credentials within the demo namespace:

kubectl create secret generic gitea \
    --namespace=porch-demo \
    --type=kubernetes.io/basic-auth \
    --from-literal=username=nephio \
    --from-literal=password=secret

5. Define Gitea Repositories in Porch

Apply the repository configuration file:

kubectl apply -f porch-repositories.yaml

6. Verify Repository Setup

Check the status of repositories in the porch-demo namespace:

kubectl get repositories -n porch-demo

Expected output:

NAME                  TYPE   CONTENT   DEPLOYMENT   READY   ADDRESS
edge1                 git    Package   true         True    http://172.18.255.200:3000/nephio/edge1.git
external-blueprints   git    Package   false        True    https://github.com/nephio-project/free5gc-packages.git
management            git    Package   false        True    http://172.18.255.200:3000/nephio/management.git

7. Run Performance Tests

Navigate to the performance test directory:

cd porch/test/performance/

Execute the performance test command:

E2E=1 go test -v ./... -repos=4 -packages=4 -timeout 60m

• repos: Number of repositories to test

• packages: Number of package revisions in each repository

Once the tests begin, the metrics can be observed.

8. Verify Prometheus Targets

Check the Prometheus targets:

http://localhost:9090/targets

You should be able to run PromQL queries here.

9. Check Metrics Output

Retrieve the captured metrics using:

curl -k http://localhost:2113/metrics

This should return all the collected performance metrics from the test execution.
