Opened: Jul 27, 2021
Severity: 3-Major

Symptoms

GUI displays "An error has occurred while trying to process your request" when deleting/creating a monitor with the same name under the same transaction.

Impact

Unable to view monitor parameters in GUI.

Conditions

(a) Create a TCP monitor, then in a single transaction delete the TCP monitor + create an HTTP monitor with same name as the TCP monitor. Example below: # tmsh create ltm monitor tcp <Name of the monitor> # echo 'create cli transaction; delete ltm monitor tcp <Name of the monitor> ; create ltm monitor http <Name of the monitor>; submit cli transaction' | tmsh # tmsh save sys config This could also occur when reconfiguring an iApp, or changing a configuration via AS3. (b) Login to the GUI and click on the monitor (GUI > Local Traffic > Monitors > (Monitor created)) you'll see "An error has occurred while trying to process your request"

Workaround

Any one of the following workarounds help: - do not use the same monitor name - do not perform the delete+create actions on a single transaction - save and load the configuration: tmsh save sys config && tmsh load sys config

Fix Information

None
