Dpinger monitoring for failover issues

[gwaitsi]

I have two VPN connections with ExpressVPN.
If the monitor address is set to google, they should with 50% packet loss

from my linux pc, if I use linux traceroute, I get the following results

• I believe this is a UDP traceroute
  traceroute to google.com (172.217.23.174), 30 hops max, 60 byte packets
  1  10.x.x.x (10.x.x.x)  35.904 ms  35.882 ms  35.873 ms
  2  hosted-by-i3d.net (31.204.154.1)  35.864 ms  35.853 ms  35.843 ms
  3  100ge.cr0-br3.smartdc.rtm.i3d.net (109.200.218.166)  35.830 ms 100ge.cr1-br3.smartdc.rtm.i3d.net (109.200.218.246)

• I believe this is an ICMP traceroute
  traceroute -I to google.com (172.217.23.174), 30 hops max, 60 byte packets
  1  10.x.x.x (10.x.x.x)  26.314 ms  26.318 ms  26.316 ms
  2  * * *
  3  * * *

If i understand this correctly, it seems that hosted-by-i3d.net (31.204.154.1) does not pass ICMP

Are there any other options/way i can monitor the vpn connection to enable failover of the vpn connection.
