UIM - Scripts running in the NAS are not executing at the scheduled time

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

The nas has some scripts scheduled every 3 minutes via NAS scheduler.

The scripts are scheduled correctly every 3 minutes. However, the execution of the scripts is not consistent. It may start later, or accumulate delay

Environment

Release : 20.1

Component : UIM NAS

Cause

In the NAS design, nas run asynchronously.

Resolution

This is expected, this is by NAS design. 

The scheduled script, if there is something else holding it up, it ends up executing it only at the next chance it can. 

The NAS does not run jobs in parallel. There is currently no way have scripts running in the nas running at exactly at X interval and so guarantee the strict 3 minutes timing.

 

An alternative to running scripts in the NAS are:
