Doc Type: Bug Fix
Doc Text:
Previously, the director auto-generated a value for 'readonly_user_name' (in /etc/ceilometer/ceilometer.conf) that exceeded the 32-characters. This resulted in ValueSizeConstraint errors during upgrades. With this release, the director now sets 'readonly_user_name' to 'ro_snmp_user' by default, which ensures compliance with the character limit.
