F5 LTM TMOS - UDP Monitor V13.0.0 - Send Packets Feature? Number of UDP Packet's Sent per Probe

Interestingly, this doesn't seem to exist in v13.0.0.

Anyway, there are some way to do that.

Options:

1 - Add 2 or more UDP monitors

If you add 2 or more UDP monitors, with the same timings, they will be basically sending 2 or more packets in total every interval.

2 - External Monitor

Create an external monitor, and you can use the logic you want.

3 - Just update the timers for the UDP monitor

This is the best option in my view, but does not fully provide the behaviour you want. If you lower the interval to 1 sec, and leave the timeout for 16 sec, after the first request that counts 0 sec, you will get 16 attempts, and only after 16 attemps and no response the pool member will marked down. You can change to any value you want, this was just an example.
