what is the time zone on the Client?

because vSphere translates the time to that of the client.

login to the server and check time

check alerts on the host what is the alarm, it is unlikely to be time!

yes, Red usually means, it's not Syncing or getting a time!

should be Black

Stop NTP, Change time on HOST, to roughly correct time, and then start NTP.

you need to check ntp server, first with software.....

make sure firewalls ports are open, check logs

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

on a windows server you can use

w32tm /stripchart /computer:<time server> /samples:5 /dataonly

if this is ESXi 5.0 phantom alarms, which is a bug.

if no alarms are present in the alarms, or Summary page.

e.g. if you enable ssh you get a warning!

to my knowlegde NTP does not give a warning or alert other than state stopped, started or appear in RED.

also HA failover, HA lack of datastores, gives a warning in Summary Page, but is not listed as an alarm.

Check Events, Tasks, Alarm, Summary page for host.

red hearing.......!!!

its damn annoying that Warnings now trigger Yellow Triangles, and its not listed in Alarms!

because technically its not an alarm, so VMware state, its a Warning!

I have an article to surpress....l.
