Issue/Introduction
This message indicates that the ESXi host is using a ramdisk for logging. Since a ramdisk is volatile and does not persist through host downtime (such as reboots and shutdowns), this may limit the amount of troubleshooting information available if any issues are encountered.
Symptoms:
You may see these messages displayed on the console of the ESXi machine or within the logs:
Syslog is not configured for persistent storage.Warning: Syslog not configured. Please check Syslog options under Configuration.Software.Advanced Settings in vSphere client.
Environment
VMware ESXi 4.1.x Installable
VMware ESXi 4.1.x Embedded
VMware ESXi 4.0.x Embedded
VMware vSphere ESXi 5.0
VMware vSphere ESXi 5.1
Resolution
The ESXi host can be configured to place logs on a scratch location on disk, or redirect logs over the network to a remote host via syslog. For more information, see:
- For ESXi 4.0, see Configure Syslog on ESXi Hosts in the Basic System Administration Guide and Enabling syslog on ESXi 3.5 and 4.x (1016621).
- For ESXi 4.1, see the Redirect System Log Files to a Remote Host section of the ESXi Installable and vCenter Server Setup Guide and Enabling syslog on ESXi 3.5 and 4.x (1016621).
- For ESXi 5.x, see the Configure Syslog on ESXi Hosts section of the vSphere Installation and Setup guide and Configuring syslog on ESXi 5.0 (2003322).
By default, ESXi 4.1 and higher attempts to use an available local scratch volume for persistent logging. All versions of ESXi can be configured to store logs on disk. For more information on how a scratch location is selected, or to configure a new scratch location, see Creating a persistent scratch location for ESXi (1033696) and Determining whether an ESXi host has persistent logging (2004773).
