Alert Triggered: NTP Servers are not reachable

Products

• VMware Aria Suite

Issue/Introduction

NTP alert triggered on a Cloud Proxy appliance. The object being triggered references local clock address of <XXX.XXX.X.X>

Environment

Aria Operations 8.X

Cause

Local NTP not enabled. 

Local Clock Address <XXX.XXX.X.X> is not binding to the Cloud Proxy IP.

Resolution

To resolve this issue:

• SSH into the Cloud Proxy appliance 
• Update the /etc/ntp.conf and enable the Local Clock Address.
  • cd /etc/
  • cp -p ntp.conf ntp.conf.bkp
  • vi ntp.conf
    • Uncomment the following line:    server <XXX.XXX.X.X>
  • service ntpd restart
• Once completed, a new metric with CP IP binding will be added to NTP metric. With Unreachable value of 0

Since the Old Data for the <XXX.XXX.X.X> existed, the alert will persists.  To cleanup the alert, delete the object from Inventory.  

Wait for 5 minutes, the new Cloud Proxy object will be readded from data collection.  The Old Data will no longer be available.

The Alert will no longer be triggered.
