Recently created SLA is not calculating

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

All the SLOs of this newly created weekly SLA are failing to calculate. They all displaying as a light blue icon, not the usual red or green which indicates calculation is occurring.

Environment

- UIM 8.5.1
- sla_engine 8.52

Cause

Operating periods defined for SLOs using 24:00 instead of 23:59 (Known issue to be fixed in UIM 9.0)

Resolution

Edit any/all defined operating periods anywhere they are specified as 24:00, to 23:59 and then recalculate the SLOs.
In a few minutes they should change color from blue to the correct status, e.g., red/green.
