1. Introduction

Disk space refers to the storage capacity of a system, measured in units such as megabytes (MB), gigabytes (GB), or terabytes (TB). For example, a computer with a 400GB hard drive can store up to 400 gigabytes of data.

Proper disk space management helps prevent low disk space issues that can affect system performance. Regular monitoring ensures your server remains in good health, avoids unexpected crashes, and provides adequate space for data and updates.

2. Setting Up Disk Space Alerts

Windows allows you to monitor disk space by creating alerts. Follow these steps to set up an alert using the System Monitor:

1. Click on Start, navigate to Administrative Tools, and open Performance.
2. Expand the Operation Logs and Alerts section.
3. Right-click on Alerts, then select New Alert Settings.
4. Enter a name for the alert (e.g., "Disk Space Alert") and click OK.
5. In the new dialog box, click on the General tab and add a comment like "Monitor free disk space on drive C."

Additional Tip:

To track disk space usage effectively, focus on critical drives like C: (system drive). Set thresholds to alert you well before critical levels are reached.

3. Configuring Alerts for Monitoring

Now that the alert is created, follow these steps to configure it:

1. Click Add to open the Add Counters dialog box.
2. Under Select counters from computer, choose your system from the list.
3. Select Logical Disk as the performance object.
4. Choose Free Space from the list of counters and select the drive you want to monitor.
5. Set the threshold value in the "Alert when value is under" box (e.g., 2000MB for 2GB).
6. Click Close to save the counter.
7. On the Actions tab, define what happens when an alert is triggered (e.g., log an event, send a message, or run a program).
8. Click Apply to save your settings.

Pro Tip:

Use the Schedule tab to automate scans. For example:

• Start Scan: Set to manual or schedule a specific time.
• Stop Scan: Set to manual, after a set duration, or at a specific time.

4. Setting Up Low Disk Space Warnings

Follow these steps to set up a low disk space warning on Windows:

1. Step 1: Open the Command Prompt (cmd) and type perfmon.
2. Step 2: Navigate to Data Collector Sets → Right-click on User Defined → Select New → Data Collector Set.
3. Step 3: Name the alert as desired, select Create manually, and click Next. Then:
   • Click Add and select Memory.
   • Choose Available MBytes and click Add.
   • Set the alert threshold to the desired disk space value (e.g., alert when below 2GB).
