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
First, identify the health status of the alert by checking the color and its corresponding description in the table above.
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.
- Navigate to
Navigate to the vCenter virtual machine, and select the Monitor tab.
Verify the swap file size by selecting the
Performancetab, and choosingAdvancedview.Monitor the swap usage on the virtual machine:
- On the
Performancetab, look for high swap usage (200 MBor above). If necessary, consider increasing the swap file size. - On the
Summarytab, check for any warning or error messages related to the swap file or its usage.
- On the
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, orhtop. Look out for processes with high%MEMorRESvalues. - If running a Windows-based virtual machine, use Task Manager or Performance Monitor to check for memory usage.
- If running a Linux-based virtual machine, use command-line utilities like
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.
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.
