NimbostratusGranular monitor to check Links and the default gateway pool (Link Controller)
The client need that a "granular" monitor of the links and default gateway pool of LC.
In the last case with F5 we added the bigip_link monitor to each link (best practice).
In this moment the client have gateway_icmp and bigip_link monitor in the Links. When we test the monitor, one ISP had latency (1000 ms or more with ping) but the monitor display available. The client describe that when they have problemas of latency o lost packets, pass the traffic only to other Link.
Whats is the best monitor or custom monitor to check the performance of links and the default gateway pool?

You can create an external monitor, that's a unix external script that is run by the OS and that returs an OK if it succeeds. The script would be configured to send one ping with a timeout of 1 second (ping -c1 -W1). You would have to catch the result of the ping, if it's OK then output something to the stdout, else output nothing.
