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. + +### Useful resources + +1.
