Perhaps, the selectservers function may help. The following example works
pretty well:
body common control
{
bundlesequence => { "test" };
}
########################################################
bundle agent test
{
vars:
"servers" slist => { "localhost" };
"result" int => selectservers("@(servers)", "80", "", "", "20",
"alive_servers");
classes:
"is_up" expression => isgreaterthan("$(result)","0");
reports:
is_up::
"OK: $(result), $(alive_servers[0])";
}
Replace localhost and "80" with host and port you want to test.
