Products

• DX Application Performance Management

Issue/Introduction

After hardware maintenance - (adding some RAM to application nodes), and cluster restart. We are not able to access admin web page (apmgatewayservice  page) to login to APM, where as all nodes restart all pods seems ok (in running state)

Environment

Release : 21.3

Resolution

 Problem with nginx controller pod which wasn't able to run correctly and was in pending state all the time.

Remove taint from master node and make sure nginx controller pod develops correctly.
