If an LTM or GTM database monitor is configured with a username to log in to the database, but without a password, pool members monitored by that monitor will be marked Down. When this issue occurs, an error message similar to the following (for a postgresql monitor in this example) will appear in the DBDaemon log file (/var/log/DBDaemon-*.log): [MonitorWorker-###] - incomplete parameters: m_connectStr:'jdbc:postgresql://###.###.###.###:##/postgres' m_user:'*********' m_password:'null' max_use:'#' m_inst_id:'******' The "incomplete parameters" and "m_password:'null'" items are the relevant parts of this error message.
Pool members monitored by a database monitor, the configured will be marked Down.
This may occur under the following conditions: -- LTM or GTM pool members are configured to use a database monitor, such as: -- mssql -- mysql -- oracle -- postgresql -- The monitor is configured with a username, but no password -- And this configuration is otherwise valid: The username is a configured in the target database with no password, and no password is required by the database for authentication of that user. -- The version of BIG-IP, or BIG-IP Engineering Hotfix, which includes a fix for Bug ID1025089.
Following is workaround for this issue: -- Configure the database user with a password, and require password authentication for the user -- Configure the database monitor with the correct password for the configured username
Database monitors with usernames configured without a password (which matches the configuration of that user in the database itself) will report correct health status of monitored pool members.
