How to get the host name of a device into the graph

[whatz]

In the tree view on the left multiple levels can be defined to classify information. In the end the final branch the tree shows hosts. Now the hostname here can be free defined by the user and is then used on top of the graphs as a label. Is it possible to add the real device name (queryable via SNMP) of a device to the graph? If yes, can you please share how?

Thank you.

This is a dirty hack. At your own risk :P

In function form_save() of host.php, change from

Code: Select all

	if ((isset($_POST["save_component_host"])) && (empty($_POST["add_dq_x"]))) {
		if (...) {
			raise_message(4);
		}else{
			$host_id = api_device_save($_POST["id"], $_POST["host_template_id"], $_POST["description"],
				...

to

Code: Select all

	if ((isset($_POST["save_component_host"])) && (empty($_POST["add_dq_x"]))) {
		if (...) {
			raise_message(4);
		}else{
			$snmp_hostname = cacti_snmp_get(
				$_POST["hostname"],
				$_POST["snmp_community"],
				".1.3.6.1.2.1.1.5.0",
				$_POST["snmp_version"],
				$_POST["snmp_username"],
				$_POST["snmp_password"],
				$_POST["snmp_auth_protocol"],
				$_POST["snmp_priv_passphrase"],
				$_POST["snmp_priv_protocol"],
				$_POST["snmp_context"],
				$_POST["snmp_port"],
				$_POST["snmp_timeout"],
				read_config_option("snmp_retries"),
				SNMP_WEBUI);

			if (!empty($snmp_hostname)) {
				$_POST["description"] = $snmp_hostname;
			}

			$host_id = api_device_save($_POST["id"], $_POST["host_template_id"], $_POST["description"],
				...

It forces to overwrite "Description" field by sysName.0 (.1.3.6.1.2.1.1.5.0) when you hit 'Create' or 'Save' button at device settings -- even if you set the field to empty.
(But nothing changed if there is any misconfiguration at SNMP options)
