Performance Evaluation Method Wrapper

Description:

  • enable prometheus addon:
tfs@tfs-vm:~/tfs-ctrl$ microk8s.enable prometheus
  • wait till prometheus becomes enabled (when enabled, press Ctrl+C):
tfs@tfs-vm:~/tfs-ctrl$ watch -n 1 microk8s.status --wait-ready
  • wait till all pods in the monitoring namespace have STATE=Running and READY=X/X (when done, press Ctrl+C):
tfs@tfs-vm:~/tfs-ctrl$ watch -n 1 kubectl get pods --all-namespaces
  • deploy as:
tfs@tfs-vm:~/tfs-ctrl$ source src/common/method_wrappers/tests/deploy_specs.sh
tfs@tfs-vm:~/tfs-ctrl$ ./deploy.sh

  • expose prometheus and grafana

    • (required) terminal 1 (grafana UI): kubectl port-forward -n monitoring service/grafana --address 0.0.0.0 3001:3000
    • (optional) terminal 2 (prometheus UI): kubectl port-forward -n monitoring service/prometheus-k8s --address 0.0.0.0 9090:9090
    • (optional) terminal 3 (alertmanager UI): kubectl port-forward -n monitoring service/alertmanager-main --address 0.0.0.0 9093:9093

  • if using remote server/VM for running MicroK8s and VSCode, forward ports 3001, 9090, 9093

  • (only used for internal framework debugging) run manual tests over the performance evaluation framework

    • terminal 4:
    export PYTHONPATH=/home/tfs/tfs-ctrl/src
python -m common.method_wrappers.tests

  • log into grafana:

    • browse: http://127.0.0.1:3000
    • user/pass: admin/admin
    • upload dashboards through "left menu > Dashboards > Manage > Import"
      • upload grafana_prometheus_component_rpc.json
      • upload grafana_prometheus_device_driver.json
      • upload grafana_prometheus_service_handler.json
    • watch in real time the dashboard

  • upload topology through WebUI and navigate

    • should see histogram changing in Grafana
