Monitor Connections in Windows 10
Un operating system as Windows 10 may need the network connection monitoring To ensure proper resource usage and protect system security, Windows 10 offers built-in options that allow users to monitor their connections without having to resort to external applications.
Access to Task Manager
El Task Manager In Windows 10, Task Manager is a powerful tool that provides detailed information about system usage, including network connections. To access Task Manager, you can use the keyboard shortcut Ctrl+Shift+Esc. Once open, head to the "Performance" tab, where you'll find graphs and statistics about network activity.
Network Information in Task Manager
El Task Manager provides real-time statistics on:
- network usage: Displays the percentage of network capacity occupancy.
- Transfer speed: Indicates the upload and download speeds in megabits per second.
- Network adapters: Lists all available adapters, including Ethernet, Wi-Fi, and Bluetooth.
Using Netstat in the Command Prompt
The command line tool netstat is a valuable utility for obtaining details about network connections. To run it, open the Symbol of the system (CMD) with administrator permissions. Then, enter the command netstat -an, which will reveal all active connections and listening ports.
Interpret Netstat Output
When using netstat -an, you will receive a list that includes:
- Local and remote IP addresses: Identifies incoming and outgoing connections.
- Connection states: Displays the status (LISTENING, ESTABLISHED, TIME_WAIT, etc.) of each connection.
- Dance: Specifies whether the connection is TCP or UDP.
Events viewer
El Events viewer Windows 10 allows users to dig deeper into system logs to identify irregularities in network connections. To access the Event Viewer, type eventvwr in the Windows search bar and select the application. In the Viewer, navigate to "Windows Logs" and then "System."
Event Categories in the Viewer
El Events viewer classifies incidents into several categories:
- Errors: Critical issues that require immediate attention.
- Warnings: Non-critical issues but could impact system performance.
- Information: General events of the system operation.
Resource and Performance Monitor
Another useful tool in Windows 10 is the Resource and Performance MonitorAccess this tool through Task Manager (Ctrl+Shift+Esc), select the Performance tab, then click Open Resource Monitor.
Resource Monitor Subtabs
El Resource Monitor It is divided into several subtabs, including:
- Red: Provides detailed information about latency, bandwidth, and active connections.
- CPU: Shows the processor usage by different processes and services.
- Disc: Details hard drive usage, including read and write activity.
- Conference proceedings: Indicates RAM consumption by system processes.
Using the Network and Sharing Center
El Center network and sharing It's a graphical interface that allows you to manage and monitor network connections. Access this center through the Windows Control Panel. Here you can see your network topology and details about each connection.
Details in the Network Center
Within the Center network and sharing, you can find:
- connection status: Information about whether the connection is active or inactive.
- Network type: Indicates whether the connection is public, private, or domain.
- Network Properties: Includes details about the IP address, subnet mask, default gateway, and DNS servers.
Viewing Data in Device Manager
El Device administrator Allows users to monitor and manage the network hardware installed on their system. To open it, use the Win+X keyboard shortcut and select "Device Manager."
Device Manager Information
The Device administrator, look for the "Network Adapters" section. When you select each adapter, you can see details about:
- Controller: Information about the version of the installed driver.
- Resources: Monitoring memory usage and other essential variables for proper functioning.
- Device status: Check if the hardware is working properly.
Using the SNMP Protocol
El Simple Network Management Protocol (SNMP) It is an advanced network monitoring tool that can be activated in Windows 10. SNMP provides detailed data on network performance and can be configured to send alerts when problems are detected.
SNMP Configuration
To enable SNMP in Windows 10:
- Open the Control panel.
- Navigate to “Programs” and select “Turn Windows features on or off.”
- Check the box SNMP and click "OK".
Once enabled, you can configure SNMP via the Service Administrator.
Monitor Network Activity with PowerShell
PowerShell is another powerful utility in Windows 10 that allows you to run detailed commands for network monitoring. Use the command Get-NetTCPConnection to get a list of all active TCP connections.
Useful Commands in PowerShell
Some useful commands in PowerShell include:
Get-NetAdapter: Lists all network adapters and their statistics.Get-NetIPConfiguration: Displays the IP settings of the network adapters.Get-NetFirewallRule: Details the firewall rules active on the system.
Automation and Scripting Tasks
Automating tasks in Windows 10 can significantly improve your ability to monitor network connections. PowerShell allows you to create scripts that can automatically execute commands.
PowerShell Script Example
An example of PowerShell script To monitor network usage could be:
«powershell«
while ($true)
Get-NetAdapterStatistics
This script saves network statistics to a file every 60 seconds.
Network Notification Settings
Windows 10 allows you to configure alerts to notify users when specific network events are detected. This can be done from the Events viewer or using custom scripts in PowerShell.
Setting Up Event Notifications
To set up a event notification, follow these steps:
- Open the Events viewer.
- Select “Create a basic task.”
- Configure the event that will trigger the notification and define the action to take, such as sending an email or running a script.
This native monitoring capability in Windows 10 eliminates the need for additional software, providing multiple tools that allow users to maintain effective control over their network connections and improve system security and performance.
