ASM - new solution failing with local file system

Products

• DX APM SaaS

Issue/Introduction

 

Recently, we deployed ASM docker installation on a few servers.

Today,  we got an alert through the UIM tool related to the missing file system on one of the servers and under the docker file path. Please find the below alert,

 testsystem205::Local file system /var/lib/docker/overlay2/a2539e591ebff70d1/merged is not available:

Though we don't see any failure in our scripts due to this alert, we are worried about this error as it may impact our running scripts in future.

 

Can you please tell what went wrong and what could be the reason of this alert ?

Release : SAAS

Cause

Resolution

1. Not related to ASM

2. Checked with UIM team - these are temp docker files

Can exclude unwanted files from UIM monitoring
