Some things to check:
Be sure that the service account user for monitor is not using any xml escapable characters in the password.
Ensure that WmPRT is running correctly on all IS servers (if clustered) - research any startup errors if any exist.
Use the “Check Status” button in MWS administration to see if both monitor host and Analytic Engine host are up and running correctly.
As a last resort:
Run DB configurator and catalog the Integration Server database schemas/users used in your JDBC Pools. Ensure that the components installed are at the latest Database Script level, if they are not, migrate the script levels to the latest version.
Good Luck!
