Symptoms

tmsh listing of a nonexistent ltm monitor returns incorrect results. (tmos)# list ltm monitor gateway-icmp http ltm monitor gateway-icmp http { adaptive disabled destination *:* interval 5 time-until-up 0 timeout 16 user-defined IP_TOS 0 user-defined SEND "GET /\r\n" }. Note there is no gateway-icmp monitor named http present. The output corresponds to the HTTP monitor.

Impact

tmsh listing of a nonexistent ltm monitor returns incorrect results. For example, the following command returns a gateway-icmp http configuration even though it does not exist: (tmos)# list ltm monitor gateway-icmp http.

Conditions

The issue arises only when querying for a nonexistent monitor whose name matches a valid monitor type, for example, http, https, icmp, and so on.

Workaround

Use the following command to return the correct results: tmsh list ltm monitor gateway-icmp gateway-icmp. (tmos)# list ltm monitor gateway-icmp does_not_exist 01020036:3: The requested monitor (/Common/does_not_exist) was not found. The listing of non-existing monitor also returns an error as expected.

Fix Information

'tmsh list ltm monitor monitor_type monitor_name' no longer returns output when the named monitor is not the of the specified monitor type. For example, if there is an HTTP monitor on a system named 'http', the query 'list ltm monitor gateway-icmp http' no longer lists the HTTP monitor, even though it is not type gateway-icmp. Note that if the command asks for a monitor that does not exist on the system, the system returns a message similar to the following: 01020036:3: The requested monitor (/Common/http1) was not found. However, if only the type is different, there is no not-found message posted.
