Runtime Network Stats Monitor

The Runtime Network Stats Monitor (RNSM) is a configurable component to display various network stats in an on-screen display at runtime, including stats from the Netcode for GameObjects (Netcode) package and custom, user-defined stats.

Prerequisites

You must use Unity Editor version 2021.2 or later.

To enable the Runtime Network Stats Monitor, install the Multiplayer Tools package.

You should now see the Runtime Network Stats Monitor from the Unity Editor top menu bar under Component > Netcode, or when searching for it by name after pressing Component > Add...

note

You must have an object selected for these options to be available.

Adding the Runtime Network Stats Monitor to a Scene

To add the RNSM to your scene, you must add it as a component to an object:

1. Select an object in your scene.

2. Add the RNSM component by either:

   1. Selecting Add Component in the Inspector tab, you can start typing RuntimeNetStatsMonitor in the search field to select the RuntimeNetStatsMonitor component.

   OR

   2. Selecting Add Component in the Inspector tab, navigate to Netcode and select RuntimeNetStatsMonitor.

   OR

   3. From the top menu bar, go to Component > Netcode > RuntimeNetStatsMonitor.

Best Practice

You can add the Runtime Network Stats Monitor component to any object in your scene and will work. However, you may want to consider creating an empty object specifically for the RNSM.

Configuring

You can configure the RNSM to your liking with its Display Elements, Panel Settings, and Styling. You can find each of these settings from the Inspector tab of the RNSM component. The RNSM package comes with default settings for each option that you can use "as is" or as guidance for creating your own.

note

The default setting for the Display Elements, Panel Settings, and Styling are disabled and not adjustable by default. To make modifications or build your own, you need to create your own configuration presets. Instructions for each customization are below.

Display Elements

Each Display Element displays one or more stats that you can add, remove, or modify under the element's Stats field.

To use the default Display Elements

1. It may already be the default in the Configuration field of the Inspector tab of the RNSM component.

OR

1. Open the RNSM component in the Inspector tab.
2. Click the circle to the right of the Configuration field.
3. Click the eye icon in the dialog menu.
4. Search for default and select the DefaultNetStatsMonitorConfiguration.

OR

1. From the Project tab, go to Packages > Multiplayer Tools > NetStatsMonitor > Assets > Configurations. The default configuration for the RNSM is in this folder.
2. Select the GameObject with the RNSM component so that it appears in the Inspector tab.
3. Drag the default configuration asset from the Project tab to the Configuration field under the RuntimeNetStatsMonitor component of your GameObject.

To configure your own Display Elements presets

1. Select the Assets folder under the Project tab.
2. Right-click in the Assets folder, then navigate to Create > Multiplayer and click on NetStatsMonitorConfiguration.
3. The configuration script appears under the Assets folder and also opens in the Inspector tab.
4. From the Inspector tab, you can use the + or - symbols to add each Display Element you want to include in this preset. Each field is configurable from here.
5. Once configured, you can add your Display Elements configuration preset to your RNSM GameObject by selecting the RNSM GameObject to appear in the Inspector tab.
6. Your Assets folder should still be visible in the Project tab, so select your newly created configuration preset to drag over the Configuration field under the RuntimeNetStatsMonitor component in the Inspector tab.
7. Save your scene.

tip

It's recommended to use the default configuration as a guide to create your own for the RNSM. You can find it from the Project tab, go to Packages > Multiplayer Tools > NetStatsMonitor > Assets > Configurations.

Panel Settings

While working in the Unity Editor with the Runtime Network Stats Monitor, you may find your screen real estate to be difficult to work with. To help remedy these situations, you can use the default panel settings or create your own to set up your workspace exactly as you want it.

To use the default Panel Settings

1. From the Project tab, go to Packages > Multiplayer Tools > NetStatsMonitor > Implementation > UI > Resources. The default panel settings configuration for the RNSM is in this folder: UnityMpToolsRnsmDefaultPanelSettings.asset.
2. Select the GameObject with the RNSM component so that it appears in the Inspector tab.
3. Drag the default panel setting asset from the Project tab to the Panel Settings Override field under the RuntimeNetStatsMonitor component of your GameObject.

note

You can use the default Panel Settings for your RNSM or use it as a starting point for custom settings. Leaving the Panel Settings Override field blank enables the default settings.

To configure your own Panel Settings presets

1. Select the Assets folder under the Project tab.
2. Right-click in the Assets folder, then navigate to Create > UI Toolkit and click on Panel Settings Asset.
3. The configuration script appears under the Assets folder and also opens in the Inspector tab.
4. From the Inspector tab, you can adjust each of the fields to fit your screen needs.
5. Once configured, you can add your Panel Settings preset to your RNSM GameObject by selecting the RNSM GameObject to appear in the Inspector tab.
6. Your Assets folder should still be visible in the Project tab, so select your newly created Panel Settings to drag over the Panel Settings Override field under the RuntimeNetStatsMonitor component in the Inspector tab.
7. Save your scene.

Styling the Runtime Network Stats Monitor

You can customize the styling of the RNSM by dragging and dropping a Unity Style Sheet (USS) onto the Custom Style Sheet field of the RNSM component from the Inspector tab.

For more information about Unity Style Sheets (USS), see the Unity Documentation on Styling the UI with USS.

note

You can use the default USS file for the RNSM to style your RNSM or use it as a starting point for custom styling. Leaving the Custom Style Sheet field blank enables the default style sheet.

To create a new style sheet for the RNSM

1. Select the Assets folder under the Project tab.
2. Right-click in the Assets folder, then navigate to Create > UI Toolkit and click on Style Sheet.
3. The new USS file appears under the Assets folder and also opens in the Inspector tab.
4. From the Inspector tab, you can use the + or - symbols to adjust each style element you want to include in this preset. Each field is configurable from here. You may find it easier to create or modify this file as a text file rather than with the Inspector (Unity Style Sheets function similarly to Cascading Style Sheets).
5. Once configured, you can add your USS configuration preset to your RNSM GameObject by selecting the RNSM GameObject to appear in the Inspector tab.
6. Your Assets folder should still be visible in the Project tab, so select your newly created style sheet to drag over the Custom Style Sheet field under the RuntimeNetStatsMonitor component in the Inspector tab.
7. Save your scene.

tip

It's recommended to use the default style sheet as a guide to create your own style sheet for the RNSM. You can find it from the Project tab under Packages > Multiplayer Tools > NetStatsMonitor > Implementation > UI > Resources > UnityMpToolsRnsmDefaultStyleSheet.uss.

USS Classes

A full list of USS class names that you can use to style the RNSM from the Project tab under Packages > Multiplayer Tools > NetStatsMonitor > Configuration > UssClassNames.cs.

Using Custom Data in the Runtime Network Stats Monitor

To add custom data to the RNSM:

1. Create your custom data as a .cs file (see example below) either in an editor of your choice to import into the Assets folder of the Projects tab. Or right-click in your Assets folder of the Projects tab, select Create > C# Script. The new .cs file opens in the Inspector tab that you can use the Open button to edit and save.
2. Once your custom data .cs file is ready, you can drag the file from your Assets folder to an object in your scene as a new component.

:::best practice

Be sure your file name and class name match for your .cs file or it won't work.

:::

Below is an example of custom data you can use with the RNSM. You can use this example as a guide to create your own custom data to explore with RNSM. Be sure to name this file as CustomStats to match the class name.

using Unity.Multiplayer.Tools.NetStats;
using Unity.Multiplayer.Tools.NetStatsMonitor;
using UnityEngine;

// User-defined metrics can be defined using the MetricTypeEnum attribute
[MetricTypeEnum(DisplayName = "CustomMetric")]
enum CustomMetric
{
    // Metadata for each user-defined metric can be defined using the MetricMetadata Attribute

    [MetricMetadata(Units = Units.Hertz, MetricKind = MetricKind.Gauge)]
    Framerate,

    [MetricMetadata(Units = Units.None, MetricKind = MetricKind.Gauge)]
    TriangleCount,

    [MetricMetadata(Units = Units.None, MetricKind = MetricKind.Gauge, DisplayAsPercentage = true)]
    CpuUsage,
}

public class CustomStats : MonoBehaviour
{
    RuntimeNetStatsMonitor m_NetStatsMonitor;

    void Start()
    {
        m_NetStatsMonitor = FindObjectOfType<RuntimeNetStatsMonitor>();
    }

    void Update()
    {
        // Once you have access to an instance of the RuntimeNetStatsMonitor
        // you can provide custom data to it using AddCustomValue,
        // using an enum with the MetricTypeEnum attribute.

        m_NetStatsMonitor.AddCustomValue(
            MetricId.Create(CustomMetric.Framerate),
            Random.Range(40, 60f));

        m_NetStatsMonitor.AddCustomValue(
            MetricId.Create(CustomMetric.TriangleCount),
            Random.Range(10000, 100000));

        m_NetStatsMonitor.AddCustomValue(
            MetricId.Create(CustomMetric.CpuUsage),
            Random.Range(0.05f, 0.4f));
    }
}
