Thank You for response,
I have verified all configurations, now ESXi is sending logs to the Syslog Server, but I want to send only the selected log no all logs to the syslog server. Additionaly, SSH sessions open/close are not being sent to the syslog server.
Below logs are from /var/log/auth.log
2020-01-28T08:43:27Z sshd[5152344]: Session opened for 'root' on /dev/char/pty/t3
2020-01-28T08:44:06Z sshd[5148135]: Session closed for 'root' on /dev/char/pty/t3
But these logs does'nt appear in /var/log/syslog.log
Any help please?
