How to use rest api to get the "Availability" attribute value of virtual server member without knowing its pool name

Hello, How can I reach pool member availability property by using rest API calling with member IP? I discover that if I call with pool name I can reach member availability but I want to access this...

    Hello Kartal.

    To get the state of one member only using their IP, you need to use 'jq'.

    # curl -sku admin https://localhost/mgmt/tm/ltm/pool?expandSubcollections=true  | jq '.items[] | select(.membersReference.items[].address == "10.100.40.112") | .membersReference.items[].state'
    "down"

    In my case, I have one pool called P-WEB112_80 which has one member node with IP 10.100.40.112.

    # tmsh list ltm pool P-WEB112_80
    ltm pool P-WEB112_80 {
        members {
            N-WEB112:http {
                address 10.100.40.112
                session monitor-enabled
                state down
            }
        }
        monitor gateway_icmp
    }

    This solves what you are requesting, but take into account that if this member is applied to more than one pool, you will see in the output "up" "up" or "down" "down" without any information about the pool, so in this case, you could use something like this.

    # curl -sku admin https://localhost/mgmt/tm/ltm/pool?expandSubcollections=true  | jq '.items[] | select(.membersReference.items[].address == "10.100.40.111") | .name, .membersReference.items[].state'
    "P-REPO_8080"
    "up"
    "P-WEB111_80"
    "up"

    If you need to collect any other field (like 'session'), you can extend the previous expression accordingly.

    Regards,

    Dario.
