    Description

      Hi

       

      I would like to same mechanism to ignore docker/k8s network interfaces from polling and showing up.

      I'm polling our Nutanix Prism Central CVM:s thru SNMP and it's running its some Docker or K8S cluster inside them and its constantly deleting and creating veth -interfaces. So log is saying like:

      vethfd3fe3c0 Interface was marked as DELETED

      vethfd3fe3c0 Interface changed: [ifDescr] '' -> 'vethfd3fe3c0'; [ifType] '' -> 'ethernetCsmacd'; [ifMtu] '' -> '1400'; [ifSpeed] '' -> '10000000000'; [ifPhysAddress] '' -> '7653e2451929'; [ifAdminStatus] '' -> 'down'; [ifOperStatus] '' -> 'down'; [ifName] '' -> 'vethfd3fe3c0'; [ifHighSpeed] '' -> '10000'; [ifPromiscuousMode] '' -> 'false'; [ifConnectorPresent] '' -> 'true'; [port_label] '' -> 'vethfd3fe3c0'; [port_label_short] '' -> 'vethfd3fe3c0'; [port_label_base] '' -> 'vethfd3fe'; [port_label_num] '' -> '3c0'; [ifLastChange] '2023-09-15 11:47:21' -> '2023-09-15 11:45:13'

      this happens many times per hour.

          You always can ignore interfaces (globally) by regex in config.php, based on your example:

          $config['bad_if_regexp'][] = "/^veth([a-f\d]{8})/i";

          Please make (as minimum) discovery debug for ports:

          ./discovery.php -d -m ports -h <device>

          But better to make full debug as Bot written.
