Accessing Event Viewer in Windows Server 2012

The primary tool for viewing Windows Server 2012 logs is the Event Viewer. This built-in utility provides a centralized interface for accessing and analyzing logs from various sources, including the operating system, applications, and security components. Here’s how to access the Event Viewer:

  1. Using the Server Manager:

    • Open Server Manager from the taskbar or Start menu.
    • In the Server Manager dashboard, click on Tools in the top-right corner.
    • Select Event Viewer from the dropdown menu.

  2. Using the Start Screen:

    • Press the Windows key to access the Start screen.
    • Type Event Viewer and press Enter.

  3. Using the Command Prompt or PowerShell:

    • Open Command Prompt or PowerShell as an administrator.
    • Type eventvwr.msc and press Enter.

Navigating the Event Viewer Interface

Once you have opened the Event Viewer, you will be presented with a user-friendly interface that allows you to easily navigate and analyze your Windows Server 2012 logs. The Event Viewer is divided into three main sections:

  • The Left Pane (Console Tree): This pane displays a hierarchical tree structure of the available log categories. The main categories include:
    • Windows Logs: Contains logs generated by the Windows operating system, such as Application, Security, Setup, System, and Forwarded Events.
    • Applications and Services Logs: Contains logs generated by individual applications and services installed on the server.
    • Subscriptions: Allows you to collect events from remote computers and store them in a central location.
  • The Center Pane (Event List): This pane displays a list of events that match the selected log category. Each event is displayed with its date, time, source, event ID, and severity level.
  • The Right Pane (Actions Pane): This pane provides a set of actions that you can perform on the selected event or log category, such as viewing event properties, filtering events, and creating custom views.

Understanding the Different Log Categories in Windows Server 2012

The Windows Logs category is the most commonly used section in the Event Viewer. It contains five subcategories, each providing valuable information about different aspects of your server's operation:

  • Application: This log contains events related to applications installed on the server, such as errors, warnings, and informational messages. This is often the first place to look when troubleshooting application-related issues.
  • Security: This log records security-related events, such as user logins, access attempts, and changes to security policies. Monitoring this log is crucial for detecting and responding to security threats.
  • Setup: This log contains events related to the installation and configuration of the Windows operating system. It can be helpful for troubleshooting issues during the setup process.
  • System: This log contains events related to the Windows operating system and its components, such as driver errors, hardware failures, and service startup/shutdown events. This is a valuable resource for diagnosing system-level problems.
  • Forwarded Events: This log stores events that have been forwarded from other computers. This is useful for centralizing log data from multiple servers in a single location.

Filtering Events to Find Specific Information

With the Event Viewer displaying potentially thousands of events, filtering becomes essential to pinpoint the specific information you need. The Event Viewer offers several filtering options to help you narrow down your search:

  1. Filtering by Event Level:

    • In the Actions pane, click on Filter Current Log.
    • In the Filter Current Log dialog box, select the desired event levels (e.g., Error, Warning, Information) in the Event level section.
    • Click OK to apply the filter.

  2. Filtering by Event Source:

    • In the Filter Current Log dialog box, select the desired event sources (e.g., Application Error, Microsoft-Windows-Kernel-Power) in the Event sources dropdown menu.
    • Click OK to apply the filter.

  3. Filtering by Event ID:

    • In the Filter Current Log dialog box, enter the specific event ID you are looking for in the Event IDs field.
    • Click OK to apply the filter.

  4. Filtering by Date and Time:

    • In the Filter Current Log dialog box, specify the desired date and time range in the Logged section.
    • Click OK to apply the filter.

Creating Custom Views for Specific Monitoring Needs

For more advanced monitoring, you can create custom views in the Event Viewer to focus on specific events that are relevant to your needs. Custom views allow you to combine events from multiple log sources and apply specific filters to create a tailored view of your server's activity. Here’s how to create a custom view:

  1. In the Actions pane, click on Create Custom View.
  2. In the Create Custom View dialog box, define the events you want to include in the view by specifying the event level, event source, event ID, and date and time range.
  3. Give your custom view a descriptive name and save it in the desired location.

Once you have created a custom view, you can access it from the Custom Views node in the left pane of the Event Viewer.

Analyzing Event Details for Troubleshooting

When you find an event that you want to investigate further, you can view its details by double-clicking on it in the event list. The Event Properties dialog box will appear, displaying detailed information about the event, including:

  • Event ID: A unique identifier for the event.
  • Log Name: The name of the log where the event was recorded.
  • Source: The application or component that generated the event.
  • Level: The severity level of the event (e.g., Error, Warning, Information).
  • User: The user account that was associated with the event.
  • Computer: The name of the computer where the event occurred.
  • Description: A detailed description of the event.
  • Event Data: Additional data associated with the event, which may include error codes, file paths, and other relevant information.

By carefully analyzing these details, you can gain a better understanding of the event and its potential impact on your server.
