Custom Metrics Development

The following two methods are supported for developing custom metrics.

• Developing custom metrics using a file

  You create a custom metrics file that meets the requirements based on the Custom Metrics File. When starting NPU Exporter, configure the -textMetricsFilePath parameter to specify the path to this custom metrics file. For details, see NPU Exporter Startup Parameters. NPU Exporter reads the custom metrics file in each data collection cycle and reports the file content to Prometheus or Telegraf.

  The development example is as follows:

  Use NPU Exporter to integrate and collect the hccs_bandwidth metric generated by the Devkit tool. For details, see NPU Exporter Integration with Devkit Deployment Guide. For an explanation of the hccs_bandwidth metric information, see HCCS Bandwidth Monitoring.

• Developing custom metrics using a plugin

  You can customize metrics by writing a plugin. Before using the plugin, learn and understand the language features of cgo and Go, and read the README to understand the usage method.
