Class MonitorLoggingStore

java.lang.Object

com.facebook.internal.logging.monitor.MonitorLoggingStore

All Implemented Interfaces:

LoggingStore

public class MonitorLoggingStore
extends java.lang.Object
implements LoggingStore

MonitorLoggingStore will read/write logs from/to the disk. When the app is stopped or crashed, the logs in the LoggingCache will be written into the disk.

Considering the data we collect are not such important so far, we will discard the logs which are send back to our server not successfully including the error of non-network, in order to reduce the usage of storage.

We will fetch the logs in the disk and send them to the server once Monitor is enabled.
