we are forwarding vmware esxi syslog to splunk by using heavy forwarder. we have not installed any universal forwarder in our esxi servers.
In splunk we have created a index(vmware_log) and created a token for index. but still we are not able to see logs in splunk cloud?

How did you expect to get the logs? Is the HF executing some kind of script or pull?

Setup:
Vmware server name - vmware_esxi01
Heavy Forwarder - bos-syslog01
In vmware server -> config -> Advance system settings -> syslog.global.loghost=tcp://bos-syslog01.acadian-asset.com

And followed "Configure ESXi hosts using the vSphere Client" section of below document

have you specified the port?

syslog.global.loghost=tcp://bos-syslog01.acadian-asset.com

after that follow this article to check if the packets are sent: https://kb.vmware.com/s/article/1031186

for example capture 10 packets on the interface vmk0 on the port 1514 and show the payload:

tcpdump-uw -i vmk0 -A -c 10 port 1514
