Products

Issue/Introduction

• Workload cannot be enabled if the VM environment is set to non-english locale (like Japanese).
• CBC sensor install fails on the Linux Workload with following log line in vmware.log:

CBLauncher: ERROR: : Fingerprint not found in key file

Environment

• Workload: All supported versions
• CBLauncher version: 1.1 and early versions
• VMware vCenter: All supported versions

Cause

CBLauncher version 1.1 does not handle non-English locale correctly.

Resolution

The issue is resolved in CBLauncher version 1.2.

Workaround Steps:
1) Uninstall cblauncher and cbsensor. Deregister sensor from CBC backend UI.
2) Get status of current locale:

sudo localectl status

(Save current locale so that it can be later restored)
3) Change system locale to english. :

sudo localectl set-locale LANG=en_US.UTF-8

4) Install cblauncher-1.1 version.
5) Edit /etc/cblauncher.conf to enable trace logs.

Change DEBUG_LEVEL=16

6) Initiate sensor install from backend.
7) Confirm that sensor installation succeeds.
8) Restore system locale back to non-english locale.
