Get pool member NAMES in irule?

Hi Sas,

unfortunately its not a build-in iRule functionality to resolve the name-labels of a member in given pool.

But you could resolve the names manually by creating a

[datagroup]

or

[array]

containing all the pool member IP/Port combinations and their name-labels.

Note: Sorry for providing an answer you may not wanted to hear... 😞

Hi Sas,

had some spare time in the evening to play around with iCall. The iCall script below will dump your Node Names and Node IPs of every single /Partition/ every 60 seconds into the datagroup "/Common/DG_IP_2_NODENAME". Enjoy... 😉

sys icall script NodeList_2_Datagroup {
    app-service none
    definition {
        set nodelist ""
        set nodecounter 0
         tmsh::log "iCall: Starting to enumerate existing node objects..."
        foreach partition [tmsh::get_config auth partition] {
            set partition "/[tmsh::get_name $partition]"
             tmsh::log "iCall: Processing Partition: $partition"
            tmsh::cd $partition
            set nodes [tmsh::get_config /ltm node]
            foreach node $nodes {
                 tmsh::log "Processing Node : $partition/[tmsh::get_name $node]"
                append nodelist "\"[tmsh::get_field_value $node "address"]\" \{ data \"[tmsh::get_name $node]\" \}\n"
                incr nodecounter
            }
             tmsh::log "Finished Partition: $partition"
        }
        tmsh::cd "/Common"
        if { not ([tmsh::list /ltm data-group] contains "ltm data-group internal DG_IP_2_NODENAME") } then {
            tmsh::log "iCall: Created the data-group \"DG_IP_2_NODENAME\"."
            tmsh::create /ltm data-group internal "DG_IP_2_NODENAME" type "string"
        } else {
             tmsh::log "iCall: The DataGroup does exist."
        }
        eval "tmsh::modify /ltm data-group internal DG_IP_2_NODENAME \{ records replace-all-with \{ $nodelist \} \}"
        tmsh::log "iCall: Updated the data-group DG_IP_2_NODENAME with \"$nodecounter\" entries."
    }
    description none
    events none
}
sys icall handler periodic NodeList_2_Datagroup {
    first-occurrence 2016-08-15:00:00:00
    interval 60
    script NodeList_2_Datagroup
}

Note: Tweak the periodic update interval (in seconds) as needed. Then use

tmsh load sys config merge from-terminal

to import and merge the partial configuration.

Cheers, Kai
