The structure of the JSON line format from the previous example is below:
```
cat exported_data.jsonl
{"metric":{"__name__":"go_cgo_calls_count","job":"victoria-metrics","instance":"self"},"values":[5],"timestamps":[1696323409458
]}
{"metric":{"__name__":"go_gc_forced_count","job":"victoria-metrics","instance":"self"},"values":[0],"timestamps":[1696323409458]}
{"metric":{"__name__":"vm_merges_total","job":"victoria-metrics","type":"storage/big","instance":"self"},"values":[0],"timestamps":[1696323409458]}
{"metric":{"__name__":"vm_http_request_errors_total","job":"victoria-metrics","instance":"self"},"values":[0],"timestamps":[1696323409458]}
```
The JSON line format allows having multiple lines in one batch. On ingestion, it is recommended to batch up to multiple
thousands of lines in one payload. Every line is represented by the following objects:
* `metric` - describes a [time series](https://docs.victoriametrics.com/keyConcepts.html#time-series) with arbitrary
number of [labels](https://docs.victoriametrics.com/keyConcepts.html#labels). Please note, `__name__` label is required.
* `values` - list of [values](https://docs.victoriametrics.com/keyConcepts.html#raw-samples) belonging to this time series;
* `timestamps` - list of unix timestamps in milliseconds associated with each value from `values` list according to their order.
