JetBrains Plugin Quick Tour¶

The majority of the work you do with Lightrun, such as troubleshooting, debugging, and performance testing, is performed directly from your integrated development environment (IDE) or the Lightrun CLI.

Using the Lightrun plugin, provided for a variety of popular IDEs (such as VSCode, IntelliJ, and PyCharm), you can insert Lightrun actions (Logs, Metrics, and Snapshots) anywhere within the source code of your running applications. Also, from within the Lightrun plugin for your IDE, you can view, in real time, the output of Lightrun actions.

And, thanks to Lightrun's comprehensive range of integrations with third-party logging tools, from the plugin, you also can route output from Lightrun Logs and Metrics to your usual logging framework (such as New Reic and DataDog).

Scope of the quick tour¶

This quick tour guide provides an overview of the main features and functionalities of the Lightrun Plugin for JetBrains (Intellij IDEA, Webstorm, Pycharm).

For more detailed information on the procedures involved in running and managing Lightrun actions in your JetBrains IDE(Intellij IDEA, Webstorm, Pycharm), see:

• Lightrun Dynamic Logs in JetBrains
• Lightrun Snapshots in JetBrains
• Lightrun Metrics in JetBrains

The JetBrains Plugin¶

Once you have authenticated the Lightrun plugin in your JetBrains IDE, your JetBrains IDE user interface should appear similar to the following image.

The following table describes the sections of the interface as numbered above:

The following sections describes the different parts in detail:

• Lightrun tool window
• Lightrun Console tool window
• Lightrun Snapshot tool window
• Lightrun Metrics tool window

The Lightrun tool window¶

The Lightrun tool window is part of the IntelliJ right-hand sidebar, and appears similarly to the following image.

The Lightrun tool window has three tabs:

• Agents
• Tags
• Actions

Agents tab¶

The Agents tab displays a list of all active agents currently attached to your JetBrains IDE and all the actions associated with each agent. You can search for agents, view and configure agent details, view action details or delete actions, and configure agent output piping in the Agents tab.

To search for an agent¶

1. Enter the agent's name or PID value into the search bar.

2. Click the Search button.

   The agent lists should appear similar to the following image

3. Click the drop-left icon on the left-hand side of an agent to display a list of all actions associated with that agent.

The following table describes the icons present in the agents and action lists and the functions of each icon.

	Icon	Function
1		Opens the information dialog box for the agent, tag, or action.
2		Toggle this button to hide/show dynamic logs in the editor. This applies to the hierarchy and can be toggled globally on the login button.
3		Use this icon to configure an agent output piping. See Viewing action output for more details.
4		Delete agent or tag actions. Only agent-activated actions can be deleted from the Agents list and tag-activated actions from the Tags list.
5		Jump to the source file and line number in the code that is associated with the action.
6		Toggle to disable or enable an action. Only agent-activated actions can be toggled from the Agents list and tag-activated actions from the Tags list.
7		Displays the current state of the action. - One checks indicates the action was submitted to the server. - Two checks indicate that it was received by the agent. - Highlighted checks indicate that the agent accepted the action. From the Agents list, the tag icon indicates the action was activated with tags and not agents, and its status can be viewed from the Tags list.
8		Indicates the the level that was configured for the log (on log rows only): Info, Debug, Warn, Error.

To view more information about an agent or Lightrun action¶

• Click the information icon on the right side of the agent or action. A dialog box will appear on your screen, showing more details about the agent/action.
