Deployment

This error started after upgrading from Liberty to Newton.

jlongstaf commented 6 years ago

This problem has been traced to an error in how the agent processes the name of health monitors. In Liberty, health monitors did not have a name attribute, but the ability to name monitors was added in Mitaka. Users that migrate their deployment from Liberty will have monitors defined with NULL value for name in the lbaa_healthmonitor table.. The agent fails to handle this resulting in the error.
