# Log

The last log events are kept in memory and are accessible via the `/api/v3/log` endpoint. You can either retrieve the log lines in the format the Core is writing them to the console (`?format=console`) or in raw format (`?format=raw`). By default they are returned in "console" format.

You can define the number of last log lines kept in memory by either setting an appropriate value in the config (`log.max_lines`) or via an enviroment variable (`CORE_LOG_MAX_LINES`).

## Read

Example:

{% tabs %}
{% tab title="Curl" %}

```bash
curl http://127.0.0.1:8080/api/v3/log \
   -H 'accept: application/json' \
   -H 'Content-Type: application/json' \
   -X GET
```

{% endtab %}

{% tab title="PyClient" %}

```python
from core_client import Client

client = Client(base_url="http://127.0.0.1:8080")
client.login()

core_log = client.v3_log_get(
    format="console"
)
print(core_log)
```

{% endtab %}

{% tab title="GoClient" %}
The GoClient always returns the logs in "raw" format.

```go
import (
    "fmt"
    "github.com/datarhei/core-client-go/v16"
)

client, _ := coreclient.New(coreclient.Config{
    Address: "https://127.0.0.1:8080",
})

events, err := client.Log()

for _, e := range events {
    fmt.Printf("%+v\n", e)
}
```

{% endtab %}
{% endtabs %}
