SAPcpmsLogUploader

public class SAPcpmsLogUploader

LogUploader can be used to upload persisted logs to SAPcpms. Applications which want to use the log upload feature must attach a handler to the Logger using ‘attachToRootLogger()’ method as soon as possible in the app’s lifecycle.

AppDelegate’s didFinishLaunchingWithOptions:

SAPcpmsLogUploader.attachToRootLogger()

Then, when you want to upload the logs:

SAPcpmsLogUploader.uploadLogs(sapURLSession: <#urlSession#>, settingsParameters: <#settingsParameters#>) { error in
// error handling
}

  • Boolean indicating if the upload of logs is enabled The configuration to upload the logs needs to be enabled in Mobile Services for the operation to be successful.

    Declaration

    Swift

    public static var logUploadEnabled: Bool { get set }

  • Boolean indicating if the uploading the logs in chunks is enabled. The default value is ‘true’.

    Declaration

    Swift

    public static var uploadLogInChunks: Bool { get set }

  • LogLevel of the LogUploadFileHandler; Use LogLevel.off to turn off logging for this handler If no LogUploadFileHandler exist the default value is ‘LogLevel.off’.

    Declaration

    Swift

    public static var logLevel: LogLevel { get set }

  • Number of days after which the logfile will be deleted without uploading. 0 means there is no expiration.

    Declaration

    Swift

    public static var logExpiration: Int

  • Default values for the maximum logfile size (maxFileSize)

    Declaration

    Swift

    public static var defaultMaxFileSize: UInt64

  • Default maximum number of backups before rolling over

    Declaration

    Swift

    @available(*, deprecated, renamed: "defaultMaxFileNum")
public static var defaultMaxBackups: Int

  • Maximum number of files before rolling over

    Declaration

    Swift

    public static var defaultMaxFileNum: Int { get set }

  • Applies the SAPcpmsLogSettings parameters on SAPcpmsLogUploader and Logger

    Declaration

    Swift

    public static func apply(sapcpmsLogSettings: SAPcpmsLogSettings)

    Parameters

    sapcpmsLogSettings

    SAPcpmsLogSettings structure with entryExpiry, maxFileSize [MB], maxFileNum and logLevel properties

  • Attaches the LogUploader’s handler to the root logger. Make sure you call this method early in the lifecycle of your application to be sure that all log messages will be written into a file that later on can be uploaded using LogUploader.uploadLogs(urlSession:destinationURL:completionHandler)

    Throws

    LoggingError.LogFileCouldNotBeCreated(description: String) if the base file is a directory and it exists.

    Declaration

    Swift

    public static func attachToRootLogger(maxFileSize: UInt64 = defaultMaxFileSize, maxFileNum: Int = defaultMaxFileNum) throws

    Parameters

    maxFileSize

    the maximum size of a single log file in bytes. Cannot be negative. Passing 0 means that a file can grow unlimited in size. (Default 5MB)
    maxFileNum

    the maximum number of logfiles that are stored on disk at the same time. Cannot be less than 1. (Default 4)

  • Attaches the LogUploader’s handler to the root logger. Make sure you call this method early in the lifecycle of your application to be sure that all log messages will be written into a file that later on can be uploaded using LogUploader.uploadLogs(urlSession:destinationURL:completionHandler)

    Throws

    LoggingError.LogFileCouldNotBeCreated(description: String) if the base file is a directory and it exists.

    Declaration

    Swift

    @available(*, deprecated, renamed: "attachToRootLogger(maxFileSize:maxFileNum:﹚")
public static func attachToRootLogger(maxFileSize: UInt64, maxBackups: Int) throws

    Parameters

    maxFileSize

    the maximum size of a single log file in bytes. Cannot be negative. Passing 0 means that a file can grow unlimited in size. (Default 5MB)
    maxBackups

    the maximum number of logfiles that are stored on disk at the same time. Cannot be less than 1. (Default 4)
