if you are installed your ESXi server at usb memory key drive, you may not able to get your log file due to the storage size. Due to that, you may follow the below guide to collect ESXi log for trouble shooting.
Here are some basic steps I used to troubleshoot this problem.
VMware ESXi hosts
On the VMware ESXi hosts check the following settings:
- Syslog destination. Open the vSphere Client. On the ESXi server, open the configuration tab and select advanced Settings. Check the Syslog.global.logHost value. The format is: protocol://FQDN:port . For example udp://example.com:514
- Is the ESXi firewall port open for syslog traffic. Open the vSphere Client, on the ESXi server, open the Configuration tab, select Security Profile, Firewall and select Properties. Check if the syslog service is enabled.
vSphere Syslog Collector
On the vSphere Syslog Collector server check the following settings:
- Is the syslog port 514 (default) listening:
- Reload and update the syslog configuration. On the ESXi host use the following command:
esxcli system syslog reload
In PowerCLI, the following command can be used to reload the syslog settings:
$esxCli = Get-EsxCli
$esxCli.system.syslog.reload()
- Is the Syslog Collector service started. Restart the Syslog Collector service if needed
After the reloading the syslog settings and restarting the Syslog Collector service the files begun to update again in the repository.
