package main import ( "fmt" "github.com/influxdata/telegraf" "github.com/influxdata/telegraf/plugins/inputs/mem" ) func main() { mem := &mem.MemStats{} metrics, err := mem.Gather() if err != nil { fmt.Printf("Error gathering memory metrics: %s\n", err.Error()) } for _, metric := range metrics { fmt.Printf("Name: %s, Fields: %v\n", metric.Name(), metric.Fields()) } }In the above example, we import the go github.com.influxdata.telegraf package and use the `mem` input plugin to gather memory metrics. We then loop through all of the gathered metrics, printing out their name and fields. The metric name in this example is `mem` because it corresponds to the `mem` input plugin. However, the actual metric names will depend on the particular input plugin being used.
