Hi @med_amine,

Once you ingest your log file into Elasticsearch, you can use a timelion expression similar to

```auto
.es(index=med*, metric=avg:bytes_sent)

```

Which shows the average bytes sent:

There are many ways to ingest your log file: [Logstash](https://www.elastic.co/products/logstash) and [Beats](https://www.elastic.co/products/beats) are both great options that we support. I suggest asking in the Logstash or Beats topics if you need help sending your log files to Elasticsearch.
