Issue/Introduction

We run API callas to collect metric data for a group of 3k servers and getting the following error in the uimapi.log,

 "Failure while trying to resolve exception [org.springframework.http.converter.HttpMessageNotWritableException]"

Environment

DX UIM 23.4
UIM API

Cause

The error  "Failure while trying to resolve exception " means It takes longer to process the API response before it reaches the timeout limit.

Resolution

Our recommendations:

- run the API calls against smaller group
- increase the timeout/resources on the server that generating the API calls.
