Issue/Introduction

A gap in data was caused by  a route change and router reboot between 14:15 and 14:20. This route change shows up in the reachability report, where the ping fails during the router change time and there is no data in the reachability report between 14:10 and 14:20. 

In the  report for interfaces, CBQoS and IP SLAs, data collection stops at 14:10 and for some and 14:15 for others.  So why does data start at 14:30 for all components except CPU (data loss is 14:10 - 14:20) and memory (data loss is 14:15-14:25)? Is there an extra 5-10mins of data loss for all components (except CPU and Memory)

 

 

 

Environment

Performance Management - all versions

Component : IM Reporting / Admin / Configuration

Cause

We need 2 good polls to generate a delta for any metric requiring deltas, such as interfaces, etc.

CPU utilization and Memory do not require a delta.
