I'm not quite sure how many ip addresses you would get from $(sys.ipv4) alone.
I usually specify an interface name to sys.ipv4 to get its ip address in return
such $(sys.ipv4).
One possible way to do what you want should be like the following code; Firstly
we create a list of ip addresses then grep to an variable.
bundle agent test
{
vars:
linux::
"all_ips" slist => { "$(sys.ipv4)","$(sys.ipv4)","$(sys.ipv4)" };
"mngmt_ip" slist => grep("10.0.50.*","all_ips");
reports:
linux::
"--> $(mngmt_ip)";
}
Cheers,
