Same name and namespace in other branches

1. 8 nagios.api.php \hook_nagios()

Does the actual work of checking something.

Parameters

$id: Optional, an identifier which is the 2nd argument passed via the URL. this is useful when you just want nagios to check a single function. example: http://mysite.com/nagios/mymodule/myId.

"myId" would be send to mymodule_nagios.

http://mysite.com/nagios/mymodule would not send any id, but would not run hook_nagios for any other modules.

Return value

array The data returned is an associative array as follows:

array( 'key' => 'IDENTIFIER', 'data' => array( 'status' => STATUS_CODE, 'type => 'state', // Can be a 'state' for OK, Warning, Critical, Unknown) or can be 'perf', which does // Cause an alert, but can be processed later by custom programs 'text' => 'Text description for the problem', ), );

STATUS_CODE must be one of the following, defined in nagios.module:

NAGIOS_STATUS_OK NAGIOS_STATUS_UNKNOWN NAGIOS_STATUS_WARNING NAGIOS_STATUS_CRITICAL

Here is an example:
