Script alert/ custom API SMS for gammu

Help
1

Hello everyone,

I recently started using librenms. I can see that there are really, really a lot of methods to send notifications but I couldn’t find one that I need the most- a script execution.

Is this possible somehow? I would like to pass the variables from an alert to it and handle it with bash myself.

If you are wondering- the end goal is to have alert SMS sent using a gammu server located in the network.

Probably, the reason that doesn’t exist is LibreNMS is open source. People just make a transport when then need something different. See the Hue lighting transport :slight_smile:

Hi,
So I decided to use API transport and to write a simple API that will exeute a remote command through PHP.

However I am struggling on properly setting API alerting. The docs says I should be using the same placeholders as I’m using for mailing.
This is my config:

api_config
api_config773×336 17.1 KB

and the result (from log) I am getting is

ssh [email protected] “gammu-smsd-inject -c /etc/gammu-smsdrc TEXT +48666666666 -unicode -text ‘{{$alert->hostname}}$alert->hostname’ -len 10000 -report”.

It just ignores the placeholders.
As soon as I can read the proper string in my api.php I am able to work this out. Can you please advise what I am doing wrong?

<?php
function log_activity($message)
{
    $date = date('Y-m-d H:i:s'); 
    error_log("$message.\n", 3, "/var/log/sms-api.log");
}
$method = $_SERVER['REQUEST_METHOD'];
$request = explode('/', trim($_SERVER['PATH_INFO'],'/'));
$input = json_decode(file_get_contents('php://input'),true);
require_once "includes/config.php";
include ('includes/functions.inc.php');
// create SQL based on HTTP method
switch ($method)
{
    case 'GET':
        {
            http_response_code(404);
            die();
            break;
        }
    case 'PUT':
        {
            http_response_code(404);
            die();
            break;
        }
    case 'POST':
        {
            //echo 'request ' . "<br><br><br>";
            //var_dump($request);
            $sms_body = $request[1];
            $sms_body = urldecode($request[1]);
            $message = "ssh [email protected] \"gammu-smsd-inject -c /etc/gammu-smsdrc TEXT " . $request[0] . " -unicode -text '" . $sms_body . "' -len 10000 -report\"";
            log_activity($message);
            //echo exec($message);
            echo $message;
            break;
        }
    case 'DELETE':
        {
            http_response_code(404);
            die();
            break;
        }
}
?>

P.S.
If I use
http://sms.example.com/api.php/+48666666666/%title%hostname/

I am getting HTTP 400 response. Probably due to Percent-encoding - Wikipedia

Maybe can someone please show me how you configured the API on your installation?

Anyone? A screenshot/ example of a working API configuration template?
