Maybe it is useful for someone else. I have written an bundle that reports
back if a client did not see the policy server for an hour. That is the
smallest value that can be set. I realy wanted to use 0.15 (each quarter
of a hour)
## Report if we lost contact with our policy server for an hour
#
bundle agent cfengine3_check_server_connectivity
{
vars:
"myhosts" slist => { hostsseen("1","notseen","address") };
classes:
"cfengine_no_connectivity" expression => reglist("@(myhosts)",
escape("$(g.policyserver)"));
reports:
cfengine_no_connectivity::
"Not seen cfengine3 policy server: $(g.policyserver) for at least a
hour";
}
