2.4 Config plugin

2.4.1 Plugin configuration

config-item	description	type	remarks
projectId	The project ID of the HUAWEI CLOUD account（project id）	String	must
accessKeyId	AK of the HUAWEI CLOUD account	String	must
accessKeySecret	SK of HUAWEI CLOUD account	String	must
regionName	Regions of Cloud Log Service	String	must
logGroupId	The log group ID of the LTS	String	must
logStreamId	The log stream ID of the LTS	String	must
totalSizeInBytes	The upper limit of the log size that can be cached by a single producer instance	int	optional
maxBlockMs	If the producer has insufficient free space, the caller's maximum block time on the send method, in milliseconds. The default is 60 seconds (60000 milliseconds), and 0 seconds is recommended. When the maxBlockMs value >= 0, it will block until the set time. If the blocking time is reached, the memory cannot be obtained, that is, an error will be reported and the log will be discarded. When the value of maxBlockMs=-1, it will be blocked until the sending is successful, and the log will not be discarded	long	optional
ioThreadCount	The thread pool size for executing log sending tasks	int	optional
batchSizeThresholdInBytes	When the cached log size in a ProducerBatch is greater than or equal to batchSizeThresholdInBytes, the batch will be sent	int	optional
batchCountThreshold	When the number of cached logs in a ProducerBatch is greater than or equal to batchCountThreshold, the batch will be sent	int	optional
lingerMs	The lingering time of a ProducerBatch from creation until it is sendable	int	optional
retries	If a ProducerBatch fails to send for the first time, the number of times it can be retried is recommended to be 3 times. If retries is less than or equal to 0, the ProducerBatch will directly enter the failure queue after the first sending failure	int	optional
baseRetryBackoffMs	The backoff time for the first retry	long	optional
maxRetryBackoffMs	Maximum backoff time for retries	long	optional
giveUpExtraLongSingleLog	For logs exceeding 1M, the data larger than 1M will be discarded after splitting	boolean	optional
enableLocalTest	是否开启跨云上报日志	boolean	optional
