Disregard the code in the example I posted before... I've been modifying this
policy a lot in the past day trying to get something functional.
Here's the example that actually uses the arrays.
5 bundle agent rhel6_services
6 {
7 vars:
8 redhat_6::
9 # running_service is what the cmd output is in the
output of ps -ef in the process table.
10 # services we want running.
11 "running_service" slist =>
{ "ntpd", "mdadm", };
12
13
14 # services we dont want running. this is what we would
find in the output of ps -ef in the process table.
15 "stop_service" slist =>
{ "/usr/sbin/atd", "/usr/sbin/abrtd",};
16
17 # running_service_name is what the service is refered
to via the chkconfig or service command.
18 # every entry from running_service needs to have an
entry here. Its what gets referenced in chkconfig and service cmds.
19 "running_service_name" string =>
"ntpd-mike";
20 "running_service_name" string =>
"mdmonitor";
21
22 "all_running_services_process_name" slist
=> getindices("running_service_name");
23 "all_running_services_service_name" slist
=> @(running_service[$all_running_services_process_name]);
24
25 # stopped_service_name is what the service is refered
to via the chkconfig or service command.
26 # every entry from stop_service needs to have an entry
here. Its what gets referenced in chkconfig and service cmnds.
27 "stopped_service_name" string => "atd";
28 "stopped_service_name" string => "abrtd";
29
30 "all_stopped_services" slist =>
getindices("stopped_service_name");
31
32
33 processes:
34 # Only raise these classes if we are on a RHEL6 host. Once the
class is defined, RHEL6 is an
35 # assumed prerequesite. the running_service variable is
expanded from an slist to an individual entry, and then
36 # that individual entry is actually checked in the process
table. If its not found,
37 # we raise the "restart" class. This class gets executed upon
in the commands section.
38 redhat_6::
39 "$(running_service)"
40 restart_class =>
canonify("$(running_service)_start");
41
42 # If we found a service in the process table that we dont want
running, then execute its stop function using service..
43 redhat_6::
44 "$(stop_service)"
45 process_stop => "/sbin/service
$(stopped_service_name[$(stop_service)]) stop";
46

48 ################################# START SERVICES
