The error log was " was collected before with the same name and label values
" but I did manage to solve this.
I had been creating a new gatherer inside the for loop, and every new
gatherer is appended. So while pushing there were multiple gatherer with
same metrics name and label set. I solved it by pushing the gatherer to
pusher object outside of the for loop.
func initPrometheus(url string) {
ctx, cancel := context.WithCancel(context.Background())
defer cancel()
i := 0
pusher := push.New(url, "test").Grouping("instance", "test")
prometheusMetrics = logger.NewPrometheusMetrics()
pusher.Gatherer(prometheusMetrics.Registry)
ticker := time.NewTicker(5 * time.Second)
defer ticker.Stop()
for {
select {
case <-ctx.Done():
fmt.Println("Stopping metric push...")
return
case <-ticker.C:
prometheusMetrics.AddInPackets("machine1", i)
fmt.Println("Attempting to push metrics...")
if err := pusher.Push(); err != nil {
fmt.Printf("Error pushing metrics to Pushgateway: %s\n", err
)
} else {
fmt.Println("Metrics pushed successfully.")
}
i++
}
}
}
