Optimizing Web Applications

This page intends to provide some guidance in optimizing web applications. Please refer to the for the list of component types, parameters, metrics, and constraints.

Telemetry configuration

No specialized telemetry solution to gather Web Application metrics is included. The following providers however can integrate with the provided metrics:

: this provider can be configured to ingest data points generated by any monitoring application able to export the data in CSV format.
integrations leveraging , or as a load generator can use this ad-hoc provider that comes out of the box and uses the metrics defined in this optimization pack.

Workflows

Applying parameters

The provided component type does not define any parameter. The workflow will optimize parameters defined in other component types representing the underlying technological stack.

A typical workflow

A typical workflow to optimize a web application is structured in three parts:

Configure and restart the application
1. Use the to interpolate the tuned parameters in the configuration files of the underlying stack.
2. Restart the application using an .
3. Wait for the application to come up using the or .
Run the test
1. use any of the to trigger the execution of the performance test against the application.
Perform the cleanup
1. use any of the to restore the application to the original state.

Here's an example workflow to perform a test on a Java web application using NeoLoad as a load generator:

name: "webapp workflow"
tasks:
  - name: Set Java parameters
    operator: FileConfigurator
    arguments:
      source:
        hostname: myapp.mycompany.com
        username: ubuntu
        key: # ...
        path: /home/ubuntu/conf_template
      target:
        hostname: myapp.mycompany.com
        username: ubuntu
        key: # ...
        path: /home/ubuntu/conf

  - name: Restart application
    operator: Executor
    arguments:
      command: "/home/ubuntu/myapp_down.sh; /home/ubuntu/myapp_sh -opts '/home/ubuntu/conf'"
      host:
        hostname: myapp.mycompany.com
        username: ubuntu
        key: # ...

  - name: Run NeoLoadWeb load test
    operator: NeoLoadWeb
    arguments:
      accountToken: NLW_TOKEN
      projectFile:
        # NeoLoad projectfile location ...
