# Event Log
This example deals with a few ways of pulling data from [SoftLayer_Event_Log](https://sldn.softlayer.com/reference/services/SoftLayer_Event_Log/). Also, uses the latest version of the SoftLayer API Client for Java (`v0.3.2` at the time of publishing this example), which does not support object filters available in the SoftLayer API, so programmatic filters are used instead.

```java
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.softlayer.api.ApiClient;
import com.softlayer.api.RestApiClient;
import com.softlayer.api.ResultLimit;
import com.softlayer.api.service.event.Log;

import java.time.LocalDate;
import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;


public class EventLogExample {

private final ApiClient client;
private final Log.Service logService;

public EventLogExample() {
String username = "set-me";
String apiKey = "set-me";
client = new RestApiClient().withCredentials(username, apiKey).withLoggingEnabled();
logService = Log.service(client);
}

public static void main(String[] args) {
EventLogExample eventLogExample = new EventLogExample();
eventLogExample.getAllTypes();
eventLogExample.getUserTypes();
eventLogExample.allLogs();
eventLogExample.loginLogs();
eventLogExample.recentLogs();
eventLogExample.systemLogs();
}
