[ilanKushnir]

the CPU temperature is not displayed on Grafana dashboards. I'm looking at a dashboard that displays the following metric: rpi_cpu_temperature_celsius I've also tried to query Prometheus and its isn't there. SCREENSHOT

• I'm using K3S
• All pods are on running state

Customizations

1. Did you customize vars.jsonnet? Put the contents below:

   {
   _config+:: {
   namespace: 'monitoring',
   },
   // Enable or disable additional modules
   modules: [
   {
     // After deployment, run the create_gmail_auth.sh script from scripts dir.
     name: 'smtpRelay',
     enabled: false,
     file: import 'modules/smtp_relay.jsonnet',
   },
   {
     name: 'armExporter',
     enabled: true,
     file: import 'modules/arm_exporter.jsonnet',
   },
   {
     name: 'upsExporter',
     enabled: false,
     file: import 'modules/ups_exporter.jsonnet',
   },
   {
     name: 'metallbExporter',
     enabled: false,
     file: import 'modules/metallb.jsonnet',
   },
   {
     name: 'nginxExporter',
     enabled: false,
     file: import 'modules/nginx.jsonnet',
   },

     enabled: false,
     file: import 'modules/elasticsearch_exporter.jsonnet',
   },
   {
     name: 'speedtestExporter',
     enabled: false,
     file: import 'modules/speedtest_exporter.jsonnet',
   },
   ],
   
   k3s: {
   enabled: true,
   master_ip: ['10.100.102.50'],
   },
   
   // Domain suffix for the ingresses
   suffixDomain: 'ilankushnir.com',
   // If TLSingress is true, a self-signed HTTPS ingress with redirect will be created
   TLSingress: true,
   // If UseProvidedCerts is true, provided files will be used on created HTTPS ingresses.
   // Use a wildcard certificate for the domain like ex. "*.192.168.99.100.nip.io"
   UseProvidedCerts: false,
   TLSCertificate: importstr 'server.crt',
   TLSKey: importstr 'server.key',
   
   // Persistent volume configuration
   enablePersistence: {
   // Setting these to false, defaults to emptyDirs.
   prometheus: false,
   grafana: false,
   // If using a pre-created PV, fill in the names below. If blank, they will use the default StorageClass
   prometheusPV: '',
   grafanaPV: '',
   // If required to use a specific storageClass, keep the PV names above blank and fill the storageClass name below.
   storageClass: '',
   // Define the PV sizes below
   prometheusSizePV: '2Gi',
   grafanaSizePV: '20Gi',
   },
   
   // Configuration for Prometheus deployment
   prometheus: {
   retention: '15d',
   scrapeInterval: '30s',
   scrapeTimeout: '30s',
   },
   grafana: {
   // Grafana "from" email
   from_address: 'ilan.kushnir@gmail.com',
   // Plugins to be installed at runtime.
   //Ex. plugins: ['grafana-piechart-panel', 'grafana-clock-panel'],
   plugins: [],
   //Ex. env: [ { name: 'http_proxy', value: 'host:8080' } ]
   env: []
   },
   }
