Which management services can be restarted on the ESXi host?

Keywords: Operation & Maintenance Linux ssh Vmware

Log in to the direct connection interface (DCUI) of ESXi 6.7 host, and we will see the following function option: Restart Management Agents. Even the description on the right is vague. What services are these so-called Management Agents?

Why not translate this Agent into "Agent", but into "service"?

The word agent is very empty, isn't it? One of these Agents is known as vpxa. I said in the previous blog that vpxa is a "spy". It is a spy assigned by vCenter Server to ESXi host. It is specially responsible for spying on ESXi messages and colluding with a service process called hostd to perform some "sabotage activities".

If you operate in the above interface and press F11 to confirm, you must restart the Management Agents. Then, a dozen services stored in the ESXi host / etc/init.d directory will be restarted. Because they are both daemons and daemons, they are similar to "services" in Linux operating system. At present, what I can see on my computer are as follows:

DCUI                     memscrubd                usbarbitrator
ESXShell                 nfcd                     vit_loader

lbtd                     swapobjd
lwsmd                    upitd

If you want to operate on the ESXi host, you will have more functions. Take ntpd, which manages time synchronization, for example:

# /etc/init.d/ntpd start
# /etc/init.d/ntpd stop
# /etc/init.d/ntpd restart
# /etc/init.d/ntpd status
# /etc/init.d/ntpd ssl_reset
