In a recent release of the Unified Monitoring Agent, the following two error messages can occur. These are expected, however, and have no impact on Unified Monitoring Agent functionality and performance. As a result, these messages can safely be disregarded:

• fail to create resource principal with error resource principal env file is not exist
• ruby: /opt/unified-monitoring-agent/embedded/lib/ruby/site_ruby/2.6.0/rubygems/stub_specification.rb:151:in `missing_extensions?‘: undefined method `missing_extensions?’ for nil:NilClass (NoMethodError)
