I just rebuild my home-lab to vSphere 5.5 U2. After setting up the syslog, I noticed 30+ messages popping up coming from my ESXi hosts. It turns out, the default logging level on the hosts is configured as verbose. Normally, this should be perfectly okay especially if you have a syslog server appliance that can make good use of it (eg. LogInsight, splunk)
Unfortunately for me, a homelab user, this is eating up both on my bandwidth and storage space. So here’s how to modify it.
Go to Configuration -> Advance Setting
Config -> HostAgent -> Log
I had mine changed to Warning.
