ojcm opened a new issue, #1154:
URL: https://github.com/apache/pulsar-client-go/issues/1154
#### Expected behavior
The `pulsar_client_consumer_processing_time_seconds` metric should contain
observations of the time it takes a consumer to process messages.
#### Actual behavior
The observations are wrong. They have values of approximately 8.5e+09 (~269
years).
#### Steps to reproduce
Create a consumer, ack some messages, check the metrics. e.g.
```
func main() {
http.Handle("/metrics", promhttp.Handler())
go http.ListenAndServe(":9090", nil)
client, err := pulsar.NewClient(pulsar.ClientOptions{
URL: URL,
Authentication: pulsar.NewAuthenticationToken(TOKEN),
})
if err != nil {
panic(err)
}
defer client.Close()
consumer, err := client.Subscribe(pulsar.ConsumerOptions{
Topic: TOPIC,
Name: "test-consumer",
SubscriptionName: "test-subscription",
})
if err != nil {
panic(err)
}
msg, err := consumer.Receive(context.Background())
if err != nil {
panic(err)
}
err = consumer.Ack(msg)
if err != nil {
panic(err)
}
time.Sleep(time.Hour)
}
```
produces
```
