+### Understand the alert
+
+The vcsa_swap_health alert presents the swap health status of the VMware vCenter virtual machine. It is an indicator of the overall health of memory swapping on the vCenter virtual machine.
+
+### Troubleshoot the alert
+
+1. First, identify the health status of the alert by checking the color and its corresponding description in the table above.
+
+2. Log in to the VMware vSphere Web Client:
+   - Navigate to `https://<vCenter-IP-address-or-domain-name>:<port>/vsphere-client`, where `<vCenter-IP-address-or-domain-name>` is your vCenter Server system IP or domain name, and `<port>` is the port number over which to access the vSphere Web Client.
+   - Enter the username and password, and click Login.
+
+3. Navigate to the vCenter virtual machine, and select the Monitor tab.
+
+4. Verify the swap file size by selecting the `Performance` tab, and choosing `Advanced` view.
+
+5. Monitor the swap usage on the virtual machine:
+   - On the `Performance` tab, look for high swap usage (`200 MB` or above). If necessary, consider increasing the swap file size.
+   - On the `Summary` tab, check for any warning or error messages related to the swap file or its usage.
+
+6. Check if there are any leading processes consuming an unreasonable amount of memory:
+   - If running a Linux-based virtual machine, use command-line utilities like `free`, `top`, `vmstat`, or `htop`. Look out for processes with high `%MEM` or `RES` values.
+   - If running a Windows-based virtual machine, use Task Manager or Performance Monitor to check for memory usage.
+
+7. Optimize the virtual machine memory settings:
+   - Verify if the virtual machine has sufficient memory allocation.
+   - Check the virtual machine's memory reservation and limit settings.
+   - Consider enabling memory ballooning for a better utilization of available memory.
+
+8. If the swap health status does not improve or you are unsure how to proceed, consult VMware documentation or contact VMware support for further assistance.
