curl -sk -u "admin:XXXXXX" -X GET "https://localhost/mgmt/tm/asm/policies?\$filter=manualVirtualServers%20eq%20/Common/vs_app1&\$select=name" | jq .
Just change "/Common/vs_app1" for the virtual server name which you want to check for ....
The first command works when the virtual server has a single ASM policy attached to it. The second command works when the virtual server has multiple ASM policies attached to it (e.g: using LTM policies).
If there are any ASM policy attached to the virtual server you should see in the output of either commands ....
