Issue/Introduction

  • Longer Time taken for FTP bundle Uploads

  • Time Out and Errors during file uploads

Resolution

The cause of Log / File upload slowness to the Broadcom Support Portal or failures may lie across multiple layers, including:

  • Log capture slowness: This could be due to the size of the inventory
    Example - A vCenter with a large inventory or one that has undergone multiple upgrades, which may result in longer log capture times

  • Packet loss in the network traffic between source and destination

  • High latency along the network path

  • Low bandwidth between the source and the destination

  • Firewall configurations on the environment

Steps to Improve the Upload speed

  • Before uploading large files, it's important to ensure the Internet connection is fast and stable enough to handle the data transfers without interruptions or failures.
    One can run speed test via Google website / External websites like Speed test/ Fast Com / Test My Net

  • Validate if the machine where the upload is being performed does not have any speed limit capped 
    (Capping internet speed can refer to the environment's ISP's data cap, which limits your total data usage and can slow down the log uploads, This could also be the environmental where the specific Organization IT team ahs set limits within the network). Please consult the ISP provider or the IT team for assistance.

  • Time taken from the datacenter environment to the Jump box machine could have slow transfer speeds, hence slowing down the whole upload process.

    Reduce Latency

    • Geographic Proximity: Ensure the jump box is geographically close to your local machines or users

Network Path Optimization

    • Use tools like traceroute, My Trace route (network diagnostics tool), to diagnose slow hops.

    • Contact ISP or Internet hosting provider if specific network segments are slow

Bandwidth and Throughput

    • Upgrade internet bandwidth if it's saturated during peak usage 

    • It is recommended to use wired Ethernet instead of Wi-Fi for local machines, to have faster uploads as the Wi-Fi resource may be shared across multiple users and devices

  • If the Primary upload method as updated in this KB - 140731 is slow, then attempt using SFTP method as explained in the KB - 202298
    There are other methods of Log Uploads like (SFTP, SCP or HTTPS) also explained in the KB - 385549

  • The vCenter Log generation time taken can be longer due to TASK and EVENTS database tables. It is recommended configure vCenter Server to retain events in the database for a limited period. Discarding events periodically ensures optimal performance of the database. This will eventually improve the time taken for the log collection, refer the below link
    Retention of Events in the vCenter Server Database
    It is also recommended to clean up old files residing in /var/core files frequently, else the time taken for Log generation will be longer.
     
    NOTE - If the vCenter has gone through multiple upgrade versions or the size of the vCenter Inventory is very large, the time taken for the log generation will be usually longer.
