Issue/Introduction

 

We are observing 5 mins delay in updating the link utilization in the CAPC tool

 

 

Environment

Release : 3.7

Component : IM Reporting / Admin / Configuration

Resolution

Poll data is written to DTO files which are copied into Vertica.

The files are read when either they reach 400MB or 5 minutes has passed since the file was created.

 

The data loading timer is not aligned with the poll timer, so you can see cases such as where the file is closed before the end of the poll, the data loaded, and a new file is created for the next 5 minutes

The data the comes in at the end of the poll after the DTO file is closed will be loaded when the new file is closed, which would be when that file reaches 400MB or 5 minutes has passed.
