After upgrading TAS "Canary not configured, skipping healthcheck" in mysql-diag

Products

• VMware Tanzu Application Service

Issue/Introduction

After upgrading to TAS 6.0.4 / 4.0.24 or newer customer reports that instead of seeing Canary status when running mysql-diag they are seeing the message "Canary not configured, skipping healthcheck"

Resolution

This is normal behavior and is safe to ignore. Replication Canary was providing negative value so was removed by R&D in TAS 4.0.24 and 6.0.4.
