Log Management API

API that controls the device log.

• BS2_GetLog: Gets certain amount of logs.
• BS2_GetFilteredLog: Gets filtered logs.
• BS2_ClearLog: Deletes all logs.
• BS2_StartMonitoringLog: Starts Real-time log streaming.
• BS2_StopMonitoringLog: Stops Real-time log streaming.
• BS2_GetLogBlob: Gets certain amount of logs based on the event mask.
• BS2_GetFilteredLogSinceEventId:​ Gets filtered logs.
• BS2_GetImageLog : Gets image logs using event ID.
• BS2_GetLogSmallBlob: [+ 2.6.4] Gets certain amount of logs based on the event mask in an efficient way.

1. id
Log record ID which automatically increases from 1 when the log is generated.

2. dateTime
The time when the log has been generated. It means the seconds past from UTC until the current time.

3. deviceID
ID of the device that generated the log.

4. userID
User ID related to log. When the value is 0, the log is not relevant to user.

5. uid
You can refer to doorID regarding door log, zoneID regarding zone log. If you do not know exactly then you can refer to uid.
Since uid, doorID, liftID, zoneID are declared as union, basically it means information such as unordered list.

6. doorID
ID of the door that generated the log.

7. liftID
ID of the lift that generated the log.

8. zoneID
ID of the zone that generated the log.

9. ioDeviceID
Door or Input device ID. When the value is 0, the log is not relevant to Door or Input device.

10. port
Port for ioDeviceID.

11. value
Port value for ioDeviceID and means below.
BS2_PORT_VALUE_UNKNOWN : -1
BS2_PORT_VALUE_OPEN : 0
BS2_PORT_VALUE_CLOSED : 1
BS2_PORT_VALUE_SUPERVISED_SHORT : 2
BS2_PORT_VALUE_SUPERVISED_OPEN : 3

12. alarm.zoneID
Zone ID that makes intrusion alarm zone alarms.

13. alarm.doorID
Door ID that makes intrusion alarm zone alarms.

14. interlock.zoneID
Zone ID that makes interlock zone alarms.

15. interlock.doorID
Door ID that makes interlock zone alarms.

16. subCode
Sub code value of log types. Use if the additional information is necessary.

17. mainCode
Main code value of log types.

18. param
It is used only when extra information on the device is needed. Usually, a time and attendance code, a port number of the door or input device is stored in the param argument. When a time and attendance code is stored, refer to the following values:

[+ 2.6.3] Additional feature of param
Only if the event code is relevant to the user.
If you add, modify or delete users directly from the device, param is 1, 0 if done through BioStar.
For example, if param was 1 with the event BS2_EVENT_USER_ENROLL_SUCCESS, it means the user was added directly on the device.
This feature is supported from the firmware version below.

19. image
Prior to SDK V2.6.0, it used the whole 1 byte and means below:
- Whether the image was included when the event occurred (true / false).

Since SDK V2.6.0, 1 byte has been changed to provide the following information by bit unit.
- Whether or not image is included. - Whether DST is applied
