Important changes

Here are some changes to highlight:

  • OPCUA node discovery
    • The OPCUA input plugins, both inputs.opcua and inputs.opcua_listener, can now be configured to discover nodes based on filtering patterns. This allows Telegraf to work in dynamic environments where nodes are added or removed on the server side.
    • If configured, the plugin will browse available nodes on the server and filter them according to your settings. It will then subscribe or listen to the remaining nodes to create metrics.
    • Use the browse settings to specify the root node and depth for the nodes to discover and one or more browse.paths patterns to filter the nodes found.
  • Oracle SQL driver support
    • Use the outputs.sql plugin to stream metrics to Oracle databases.
    • Custom header support for Kafka
    • Set custom record headers for messages sent by outputs.kafka. The header values support templating, taking the metrics sent as input.
  • MongoDB custom metadata
    • Set custom metadata in outputs.mongodb for the MongoDB documents written by specifying a tag subset. This allows easier and more efficient querying while keeping the full metric information.
  • OpenTelemetry improvements
    • The outputs.opentelemetry plugin now allows using a proxy or authenticating with a token.
  • More system details
    • The inputs.system plugin provides more details on the host system, such as DMI hardware and operating system information.
    • To include this information, please opt in by adding the respective include settings in your configuration.
