Hi,

We run some metricbeat in our machines. And collect the run log every 10 mins.  
After check the log at /etc/log/metricbeat, we feel puzzled. And we don't find any document about it.

One log record like followed:

```
fetches.system-core.events=40
fetches.system-core.success=10
fetches.system-cpu.events=10
fetches.system-cpu.success=10
fetches.system-diskio.events=12
fetches.system-diskio.success=2
fetches.system-load.events=10
fetches.system-load.success=10
fetches.system-memory.events=10
fetches.system-memory.success=10
fetches.system-network.events=710
fetches.system-network.success=10
fetches.system-process.events=58
fetches.system-process.success=2
libbeat.es.call_count.PublishEvents=22
libbeat.es.publish.read_bytes=14517
libbeat.es.publish.write_bytes=570384
libbeat.es.published_and_acked_events=850
libbeat.publisher.messages_in_worker_queues=850
libbeat.publisher.published_events=850

```

I guess the "fetches" means the collector, and the libbeat is the transfer.

"fetches.system-core.events=40" & "fetches.system-core.success=10"  
The above means there are 30 event transfer failed to the Elasticsearch?

If it's failed, where can I find the data, or it be dropped?

But the "libbeat.publisher.published\_events=850" means all of the event is transfer successful?

Thank you
