Using https monitor with Oracle Access Manager

however it still marking the member as down

can you try tcpdump? do you have server's ssl key to decrypt?

you may have to remove the monitor from pool first, start tcpdump and then assign it back to the pool.

 tcpdump -nni 0.0:nnn -s0 -w /var/tmp/output.pcap host x.x.x.x and host y.y.y.y -v
x.x.x.x is non-floating self ip on server vlan
y.y.y.y is server ip
