Fixed In:

Opened: May 24, 2019

Severity: 3-Major

Symptoms

- Monitors are firing and are being sent to a pool-member or node address rather than a monitor's alias address. - Running the command 'tmsh load /sys config' reports an error: 01070038:3: Monitor /Common/a-tcp address type requires a port.

Impact

Monitors are sent to an incorrect IP address. tmsh load /sys config will fail to load the configuration.

Conditions

-- Create a monitor without an alias address. -- Modify the monitor later in the TMUI to specify an alias address.

Workaround

There are two workarounds: -- Delete and recreate the monitor and specify the correct alias address at creation time. -- Fix the monitor definition using tmsh.

Fix Information

None
