=head1 DESCRIPTION |
38
|
|
|
|
|
|
|
|
39
|
|
|
|
|
|
|
This subclass of L<Siebel::Srvrmgr::Daemon::Action> will try to find a L<Siebel::Srvrmgr::ListParser::Output::Tabular::ListComp> object in the given array reference |
40
|
|
|
|
|
|
|
given as parameter to the C<do> method and compares the status of the components (CP_DISP_RUN_STATE) with the array reference given as parameter. |
41
|
|
|
|
|
|
|
|
42
|
|
|
|
|
|
|
The C<do> method of C<Siebel::Srvrmgr::Daemon::Action::CheckComps> uses L<Siebel::Srvrmgr::Daemon::ActionStash> to enable the program that created the object |
43
|
|
|
|
|
|
|
instance to be able to fetch the information returned. |
44
|
|
|
|
|
|
|
|
45
|
|
|
|
|
|
|
This module was created to work close with Nagios concepts, especially regarding threshold levels (see C<new> method for more details). |
46
|
|

|

|
=head2 new |
50
|
|
|
|
|
|
|
|
51
|
|
|
|
|
|
|
The new method returns a instance of L<Siebel::Srvrmgr::Daemon::Action::CheckComps>. The parameter expected are the same ones of any subclass of |
52
|
|
|
|
|
|
|
L<Siebel::Srvrmgr::Daemon::Action>, but the C<params> attribute has a important difference: it expects an array reference with instances of classes |
53
|
|
|
|
|
|
|
that have the role L<Siebel::Srvrmgr::Daemon::Action::CheckComps::Server>. |
54
|
|
|
|
|
|
|
|
55
|
|
|
|
|
|
|
The server instance itself will expect to have multiple instances of objects representing a Siebel Component and those instances must be of a class that has the |
56
|
|
|
|
|
|
|
Moose role L<Siebel::Srvrmgr::Daemon::Action::CheckComps::Component> applied. |
57
|

|
Expects a array reference as the buffer output from C<srvrmgr> program as a parameter. |
90
|
|
|
|
|
|
|
|
91
|
|
|
|
|
|
|
This method will check the output from C<srvrmgr> program parsed by L<Siebel::Srvrmgr::ListParser::Output::Tabular::ListComp> object and compare each component recovered status |
92
|
|
|
|
|
|
|
with the status defined in the array reference given to C<params> method during object creation. |
93
|
|
|
|
|
|
|
|
94
|
|
|
|
|
|
|
It will return 1 if this operation was executed successfuly and request a instance of L<Siebel::Srvrmgr::Daemon::ActionStash>, calling it's method C<instance> and then |
95
|
|
|
|
|
|
|
C<set_stash> with a hash reference as it's content. Otherwise, the method will return 0 and no data will be set to the ActionStash object. |
96
|
|
|
|
|
|
|
|
97
|
|
|
|
|
|
|
The hash reference stored in the ActionStash object will have the following structure: |
98
|
|
|
|
|
|
|
|
99
|
|
|
|
|
|
|
$VAR1 = { |
100
|
|
|
|
|
|
|
'foobar_server' => { |
101
|
|
|
|
|
|
|
'CompAlias1' => 0, |
102
|
|
|
|
|
|
|
'CompAlias2' => 1 |
103
|
|
|
|
|
|
|
}, |
104
|
|
|
|
|
|
|
'foobar2_server' => { |
105
|
|
|
|
|
|
|
'CompAlias1' => 1, |
106
|
|
|
|
|
|
|
'CompAlias2' => 1 |
107
|
|
|
|
|
|
|
} |
108
|
|
|
|
|
|
|
}; |
109
|
|
|
|
|
|
|
|
110
|
|
|
|
|
|
|
If the servername passed during the object creation (as C<params> attribute of C<new> method) cannot be found in the buffer parameter, the object will raise an |
111
|
|
|
|
|
|
|
exception. |
112
|
|
|
|
|
|
|
|
113
|
|
|
|
|
|
|
Beware that this Action subclass can deal with multiple servers, as long as the buffer output is from a C<list comp>, list all server/components that |
114
|
|
|
|
|
|
|
are part of the Siebel Enterprise. |
