Metrics

Go runtime metrics

These metrics are prefixed with go_ and provide general information about the process like:

  • Garbage-collector statistics
  • Memory usage
  • Go go-routines

gRPC API metrics

These metrics are prefixed with grpc_ and provide metrics about the gRPC API (both the external gRPC / REST API and the gRPC API used by LoRa Server), e.g.:

  • The number of times each API was called
  • The duration of each API call (if enabled in the Configuration)

Join-Server API

These metrics are prefixed with api_joinserver_ and provide metrics about the LoRa App Server Join-Server API endpoint. This endpoint is used by LoRa Server when an OTAA Join-Request is received.
