Aria Operations dashboard remains in a "loading" state.

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

The dashboard is stuck in a "loading" state and fails to display data.

For Example:

Environment

Aria Operations 8.18.X

Cause

This is due to large ".dat" file which is more than 2GB for the objects in /data directory .

Resolution

Follow the steps below to resolve the issue: 

Note: Before performing the below steps, take snapshot of Aria Operations Cluster, Refer: Snapshot Creation in VMware Aria Operations 

1. SSH to Aria Operations nodes. 
2. Run command on each node: find /storage/db/vcops/data -type f -size +1024M -exec du -m {} + | sort -rn
3. The command above shows the large .dat file and its internal ID: ID1.

Example

root@AriaOperationsnode1 [ ~ ]# find /storage/db/vcops/data -type f
c du -m () + | sort -rn
/storage/db/vcops/data/26/<ID1>/2025_07_<ID1>.dat
/storage/db/vcops/data/26/<ID1>/2025_06_<ID1>.dat
/storage/db/vcops/data/26/<ID1>/2025_08_<ID1>.dat

4. Search for the ID (ID1) in Aria Operations UI at: Configurations>>Inventory Management>>Objects>>Search ID1 in filter:

5. Choose the object and click "X" to remove it and its associated ".dat" files.

Note: Deleting the object will also remove its historical data.

6. New ".dat" files will be created again in the next cycle. 
7. Take the cluster offline, then bring it back online under Cluster Status in the Admin UI.
