Right mouse click over the image and select "copy". Then "paste" in your applications. I do it all the time. When in graph zoom, you have to avoid the center of the image. Do it off to the side.

For those wondering, I'm still here, but lost in the shadows. Yearning for less bugs. Who want's a Cacti 1.3/2.0? Streams anyone?

How can I programmatically grab a graph image using curl?

I want grab a graph every hour or so and have it available to view on a website completely different/separated from cacti.

Can I pass in credentials with the request line?


TIA.

Check out "Graph Export" to auto-generate graphs. Then use your favorite tool to transfer to another server.

Thanks for the reply.

I'd like to grab an individual graph without having to turn on Graph Export for the whole server.

What I ended up doing was adding a bit of code to include/auth.php at the top right under the version check:

Code: Select all

if (!empty($_GET['auto_auth_key']))
{
	if ($config['auto_auth_key'] == $_GET['auto_auth_key'])
	{		//	$_POST["login_username"] . "' and password = '" . md5($_POST["login_password"]
		$username = preg_replace('/.*?(\w+).*/', '\1', trim($_GET['login_username']), 1);
		$password = sql_sanitize(md5(trim($_GET['login_password'])));
		$where = "username='$username' AND (password='$password')";
		$auto_auth_user_id = db_fetch_cell("select id from user_auth where $where");
		if (!empty($auto_auth_user_id)) {
			$_SESSION["sess_user_id"] = $auto_auth_user_id;
		}
	}
}
and then setting a hash value in the global $config var in config.php:
$config['auto_auth_key'] = 'MYSECRETAUTHKEY'

This allows me to put the entire graph_view.php request along with a normally defined users login name and password into a straight URL and pull down a graph image.
