Detailed Description

The default ILogUploadStrategy implementation.

The decision algorithm depends on the log delivery status:

The normal work flow (the Operations server successfully receives logs).

The LogUploadStrategyDecision::UPLOAD decision applies in two cases: 1) the consumed volume of the log storage is equal or greater than the corresponding value, specified in the strategy via setVolumeThreshold() (DEFAULT_UPLOAD_VOLUME_THRESHOLD is used by default); 2) the number of collected logs is equal or greater than the corresponding value, specified in the strategy via setCountThreshold() (DEFAULT_UPLOAD_COUNT_THRESHOLD is used by default);

The delivery error.

If one of LogDeliveryErrorCode errors has occurred, the LogUploadStrategyDecision::NOOP will apply until the retry period, specified via setRetryPeriod (DEFAULT_RETRY_PERIOD is used by default) will have elapsed.

The delivery timeout.

In this case the strategy tries to switch to the next transport channel supported the logging feature.

virtual LogUploadStrategyDecision kaa::DefaultLogUploadStrategy::isUploadNeeded ( ILogStorageStatus & status )

virtual

Decides whether the log upload is needed.

The decision is made based on the current log storage status and, depending on the strategy implementation, on some additional information.

Parameters

[in] status The log storage status.

Returns: The log upload decision.

Implements kaa::ILogUploadStrategy.

Reimplemented in kaa::RecordCountWithTimeLimitLogUploadStrategy, kaa::StorageSizeWithTimeLimitLogUploadStrategy, kaa::PeriodicLogUploadStrategy, kaa::RecordCountLogUploadStrategy, and kaa::StorageSizeLogUploadStrategy.

virtual void kaa::DefaultLogUploadStrategy::onFailure	(	ILogFailoverCommand &	controller,

virtual

Callback is used when the log delivery is failed.

Parameters

[in]	controller
[in]	code	The reason code of the log delivery failure.

See Also: LogDeliveryErrorCode

Implements kaa::ILogUploadStrategy.
