+# Nag notice
+## manual steps
+
+- `cd /usr/share/javascript/proxmox-widget-toolkit`
+- `cp proxmoxlib.js proxmoxlib.js.bak`
+- `nano proxmoxlib.js`
+- search for "function(orig_cmd) {" and add "orig_cmd();" and "return;" just after it
+- `systemctl restart pveproxy.service`
+

+
+# Sensor data
+
+## 1) Lets install lm-sensors to show us the information we need. Type the following in the proxmox shell
+
+    apt-get install lm-sensors
+
+Next we can check if its working. To do this we can type `sensors`
+
+The main part we are interested in is:
+
+	root@pve:~# sensors
+
+	coretemp-isa-0000
+	Adapter: ISA adapter
+	Package id 0:  +23.0°C  (high = +84.0°C, crit = +100.0°C)
+	Core 0:        +21.0°C  (high = +84.0°C, crit = +100.0°C)
+	Core 1:        +21.0°C  (high = +84.0°C, crit = +100.0°C)
+	Core 2:        +22.0°C  (high = +84.0°C, crit = +100.0°C)
+	Core 3:        +19.0°C  (high = +84.0°C, crit = +100.0°C)
+
+If you see this you are good to go!
+
+## 2) Adding the output of sensors to information
+
+Here we will use `Nano` to edit some files. In your shell, type the following:
+
+    nano /usr/share/perl5/PVE/API2/Nodes.pm 
+
+Next, you can press **F6** to search for `my $dinfo` and press **Enter**
+
+The code should look like this:
+
+         $res->{pveversion} = PVE::pvecfg::package() . "/" .
+             PVE::pvecfg::version_text();
+ 
+         my $dinfo = df('/', 1);     # output is bytes
+
+We are going to add the following line of code in between: `$res->{thermalstate} = \sensors\;`
+
+So the final result should look like this:
+
+        $res->{pveversion} = PVE::pvecfg::package() . "/" .
+            PVE::pvecfg::version_text();
+
+        $res->{thermalstate} = `sensors`;
+
+        my $dinfo = df('/', 1);     # output is bytes
+
+Now press **Ctrl+O** to save and **Ctrl+X** to exit.
+
+## 3) Making space for the new information
+
+Next we will need to edit another file, So once again we will use `Nano`
+
+Type the following command into your shell: `nano /usr/share/pve-manager/js/pvemanagerlib.js`
+
+Once in press **F6** to search for my `widget.pveNodeStatus` and press **Enter**
+
+You will get a snippit of code that looks like this:
+
+     Ext.define('PVE.node.StatusView', {
+     extend: 'PVE.panel.StatusView',
+     alias: 'widget.pveNodeStatus',
+ 
+     height: 300,
+     bodyPadding: '5 15 5 15',
+ 
+     layout: {
+         type: 'table',
+         columns: 2,
+         tableAttrs: {
+             style: {
+                 width: '100%'
+             }
+         }
+     },
+
+Next change the `bodyPadding: '5 15 5 15',` to `bodyPadding: '20 15 20 15',`
+
+As well as `height: 300,` to `height: 360,`
+
+**Dont close the file this time!**
+
+## 4) Final part to edit
+
+Ok so you know the drill by now press **F6** to search for `PVE Manager Version` and press **Enter**
+
+You will see a section of code like this:
+
+         {
+             itemId: 'version',
+             colspan: 2,
+             printBar: false,
+             title: gettext('PVE Manager Version'),
+             textField: 'pveversion',
+             value: ''
+         }
+
+Ok now we need to add some code after this part. The code is:
+
+        {
+            itemId: 'thermal',
+            colspan: 2,
+            printBar: false,
+            title: gettext('CPU Thermal State'),
+            textField: 'thermalstate',
+            renderer:function(value){
+                const c0 = value.match(/Core 0.*?\+([\d\.]+)Â/)[1];
+                const c1 = value.match(/Core 1.*?\+([\d\.]+)Â/)[1];
+                const c2 = value.match(/Core 2.*?\+([\d\.]+)Â/)[1];
+                const c3 = value.match(/Core 3.*?\+([\d\.]+)Â/)[1];
+                return `Core 0: ${c0} ℃ | Core 1: ${c1} ℃ | Core 2: ${c2} ℃ | Core 3: ${c3} ℃`
+            }
+        }
+
+Therefore your final result should look something like this:
+
+        {
+            itemId: 'version',
+            colspan: 2,
+            printBar: false,
+            title: gettext('PVE Manager Version'),
+            textField: 'pveversion',
+            value: ''
+        },
+        {
+            itemId: 'thermal',
+            colspan: 2,
+            printBar: false,
+            title: gettext('CPU Thermal State'),
+            textField: 'thermalstate',
+            renderer:function(value){
+                const c0 = value.match(/Core 0.*?\+([\d\.]+)Â/)[1];
+                const c1 = value.match(/Core 1.*?\+([\d\.]+)Â/)[1];
+                const c2 = value.match(/Core 2.*?\+([\d\.]+)Â/)[1];
+                const c3 = value.match(/Core 3.*?\+([\d\.]+)Â/)[1];
+                return `Core 0: ${c0} ℃ | Core 1: ${c1} ℃ | Core 2: ${c2} ℃ | Core 3: ${c3} ℃`
+            }
+        }
+
+Now we can finally press **Ctrl+O** to save and **Ctrl+X** to exit.
+
+## 5)Restart the summery page
+
+To do this you will have to type in the following command: `systemctl restart pveproxy`
