# Diagnostic

## Requirements

Linux Control Center = 2.10.X or higher

## Overview

The Linux Control Center needs to maintain a connection with some external components to work properly. Therefore, the *Diagnostics* tool was created to validate the communication status of the Console with these components.

## Objective

This document aims to demonstrate how to test the communication of the Console with the Worker, Vulnerability API and the LCC Customer Portal Server.

## Communication Test

1. Click on **Config** in the left side menu of the LCC

   ![](/files/c92CYrW3uRE96JP1CfPx)
2. Click on **Diagnostics**.

   ![](/files/NILvNoVIonmgGX3QHVRz)
3. Click on **Test**.

* This action will test the connection of the LCC Console with the listed components. The Status column will display a red **X** if communication fails.
