NimbostratusCheck pool status in an iRule
I am trying to write an iRule that will monitor the status of many devices before forwarding to one device. I'll try to skip the details unless it becomes necessary to explain, but is it possible to d...

NimbostratusI don't realy know what you are trying to do, but here is a simple code that would do a status check on members of a pool.
set POOL01 "pool_my-pool"
array set POOL01_MEMBERS {
"10.1.1.40" "80"
"10.1.1.41" "80"
"10.1.1.42" "80"
"10.1.1.43" "80"
}
set LBSTAT ""
foreach {IP PORT} [array get POOL01_MEMBERS] {
if { $LBSTAT equals "" } {
set LBSTAT "$IP = [LB::status pool $POOL01 member $IP $PORT]"
}
else {
set LBSTAT "$LBSTAT, $IP = [LB::status pool $POOL01 member $IP $PORT]"
}
}
log local0. "$LBSTAT"
As much as I know you have to define the pool members both in the iRule and as members of a regular pool in the GUI. I don't know any way to extract the pool members from the BigIP config from an iRule.
You may also consider using [active_members ] if the only thing you want to check is the active members compared to how many members the pool have.
