Could you explain about parameters in loadable modules?

[Gutsycat]

I have a simple application and want to "convert" it to zabbix loadable module.

Here an application:
Input: my_app --ipaddress <address> --number <number> --string <string>
Output: number (with stdut)

I need somehow pass these parameters to module and get output into zabbix. Could you explain this part? That's all I need.

Hello,

basically you must define your input parameters in zabbix module, dummy.ping, dummy.echo,dummy random in this example

static ZBX_METRIC keys[] =
/*	KEY			FLAG		FUNCTION	TEST PARAMETERS */
{
	{"dummy.ping",		0,		dummy_ping,	NULL},
	{"dummy.echo",		CF_HAVEPARAMS,	dummy_echo,	"a message"},
	{"dummy.random",	CF_HAVEPARAMS,	dummy_random,	"1,1000"},
	{NULL}
};

Every one of them is an item key.

You must write something like that:

{"your_app.function",		CF_HAVEPARAMS,	your_function_name,	"1par,2par,3par"},

Then write your function with your_function_name, specify parameters and output

	param1 = get_rparam(request, 0);
	param2 = get_rparam(request, 1);
	param3 = get_rparam(request, 2);

here goes your code, which generates some variable your_output_number

(SET_UI64_RESULT(result, your_output_number)
