After you install or upgrade to VMware Application Proxy version 1.0.0.1, you must set up accurate timekeeping as part of the deployment. If the time settings between VMware Application Proxy and vRealize Operations Manager are not synchronized, you will face agent installation and metric collection issues. Ensure time synchronization between the endpoint VMs, vCenter Server, ESX Hosts and vRealize Operations Manager using the Network Time Protocol (NTP).

Procedure

  1. Log in to the VMware Application Proxy VM and modify the ntp.conf file available in /etc/ntp.conf by adding following in the following format:
    server time.vmware.com
    Note:

    Replace time.vmware.com with a suitable time server setting. You can use the FQDN or IP of the time server.

  2. Enter the following command to start the NTP daemon:
    systemctl start ntpd
  3. Enter the following command to enable the NTP daemon:
    systemctl enable ntpd
    
  4. Run the following command to verify if NTP is configured correctly:
    ntpstat

    If NTP is synchronized correctly, you will see a message similar to the following:

    synchronised to NTP server (10.113.60.176) at stratum 3
     
       time correct to within 50 ms
     
       polling server every 64 s
