You can issue a ps auwx | grep varnish and look at the line for the process:

/usr/sbin/varnishd -P /var/run/ -a :80 -f 
/etc/varnish/default.vcl -T XX.XX.XX.XX:XX -t 120 -w 100,4000,120 -u 
varnish -g varnish -S /etc/varnish/secret -s malloc,2G

This shows Varnish is using malloc and is allocated 2G of memory.

You can also issue top and find the varnishd entry:

23193 varnish   15   0 4064m 1.5g  81m S  2.0 15.8  70:19.87 varnishd

This shows we are using 1.5G of resident memory for our Varnish instance.
