1: Check the Available Disk Space

2: Write VM-Support to a Different Location

The vm-support script can be issued with the option to write to a specified path like a vmfs datastore.

# vm-support -w /vmfs/volumes/datastore 

For detailed instructions on how to run vm-support from the /tmp directory to avoid running out of memory, see VMware Knowledge Base Article ID# 1002520.

3: Configure a Syslog

If you already have a syslog server created, you can send all new logs to a syslog server by configuring ESXi. (Note: Existing logs are not sent to the newly created syslog server.)

1. Open VMware vSphere Client and select the ESXi host.
2. Click the Configuration tab.
3. In the software section, click Advanced Settings.
4. Click Syslog.
5. For Syslog.Remote.Hostname, enter the hostname or IP of the syslog server.
