Issue/Introduction

After trying to press the button (Bring the cluster Online) in the Admin interface for Aria Operations, all the analytics nodes remain in status "Waiting for analytics".

Environment

Aria Operations 8.18.x

Resolution

1. 1. Take Aria Ops Offline via the admin interface.
      
      
   2. If the cluster (all the nodes are in offline status), take a Snapshot Creation in VMware Aria Operations
      
      
   3. SSH each node using root credentials.
      
      
   4. Run the date command on each node and compare if the date and time are the same.
      
      If the date and time are different across the nodes, please correct the date, time, or both on the affected node(s). The date and time must be the same on all Aria Ops nodes.
      
      
   5. Fix the affected node(s). At the same time, while the Aria Operations cluster is offline, update the date and time by running the hwclock command.
      
      For example, set the date and time to December 24 2025 6:00 PM by running the following commands:
      hwclock --set --date="12/24/2015 18:00:00"
      hwclock --hctosys
      date # Used to verify the time was correctly set
      
      
      
   6. Bring the Aria Operations cluster online via the admin Interface.
