The following are possible causes for this failure:


Configuration errors: Most common issues are: Test user password is invalid or expired, Test users have not been configured correctly for this Pool. Please refer Synthetic Transaction Internal Alerts View for more details. To fix this problem, check if test users are assigned correctly for the pool being monitored, using the New-CSwatcherNodeConfiguration cmdlet. Also ensure that these test users are correctly provisioned and enabled for services.

Server/Component is down for Maintenance: Please ensure that you put Synthetic Transactions in maintenance mode before performing server/pool maintenance. To do this, use the Start Pool maintenance task in the Pools view.
