To verify if the ESX Server management service (vmware-hostd) is running:

  1. Log in as root to your ESX host with an SSH client.

  2. Run the following command:
    ps -ef | grep hostd
    The output appears similar to the following if vmware-hostd is running: 
    [root@server]# ps -ef | grep hostd
    root     23204     1  0 15:27 ?        00:00:00 /bin/sh /usr/bin/vmware-watchdog -s hostd -u 60 -q 5 -c /usr/sbin/hostd-support /usr/sbin/vmware-hostd -u
    root     23209 23204  1 15:27 ?        00:04:23 /usr/lib/vmware/hostd/vmware-hostd /etc/vmware/hostd/config.xml -u
    root     26450 26396  0 20:57 pts/3    00:00:00 grep hostd
    [root@server]# 
    The output appears similar to the following if vmware-hostd is not running:
    [root@server]# ps -ef | grep hostd
    root     26659 26396  0 21:03 pts/3    00:00:00 grep hostd
    [root@server]#
