Hi,
I've been playing with class persistence recently. The idea is to run
potentially heavy class-generating commands not too frequently, but
being able to use those classes every time Cfengine runs.
What I have now is this:
----------------------------------------------------------------
bundle common get_the_classes
{
vars:
hourly::
"test_command"
string => "some heavy command";
classes:
hourly::
"yes_test"
expression => strcmp("yes",execresult("$(test_command)","noshell"));
"not_test"
expression => strcmp("no",execresult("$(test_command)","noshell"));
reports:
yes_test::
"$(sys.fqhost) test = yes!",
classes => persist("yes_test","120");
not_test::
"$(sys.fqhost) test = no!",
classes => persist("not_test","120");
!yes_test.!not_test::
"OOPS! $(sys.fqhost) - Something is wrong with test classes!";
}
body classes persist(class,time)
{
promise_repaired => { "$(class)" };
persist_time => "$(time)";
timer_policy => "reset";
}
----------------------------------------------------------------
(The class "hourly" is a splayclass).
Is it possible to make the classes persistent in the class promise
somehow, or do I have to set the persistence whenever the class is
actually used (like with reports in the example above)?
I've tried this:
classes:
hourly::
"yes_test"
expression => strcmp("yes",execresult("$(test_command)","noshell")),
classes => persist("yes_test","120");
But that didn't do the trick, although it passed as valid syntax.
Cheers,
