ZanderXu resolved HADOOP-18920. ------------------------------- Fix Version/s: 3.4.0 Hadoop Flags: Reviewed Resolution: Fixed > RPC Metrics : Optimize logic for log slow RPCs > ---------------------------------------------- > > Key: HADOOP-18920 > URL: https://issues.apache.org/jira/browse/HADOOP-18920 > Project: Hadoop Common > Issue Type: Improvement > Reporter: Haiyang Hu > Assignee: Haiyang Hu > Priority: Major > Labels: pull-request-available > Fix For: 3.4.0 > > > HADOOP-12325 implement a capability where "slow" RPCs are logged in NN log. > Current processing logic is the "slow" RPCs are to be those whose processing > time is outside 3 standard deviation. > However, in practice it is found that many logs of slow rpc are currently > output, and sometimes RPCs with a processing time of 1ms are also declared as > slow, this is not in line with actual expectations. > Therefore, consider optimize the logic conditions of slow RPC and add a > `logSlowRPCThresholdMs` variable to judge whether the current RPCas slow so > that the expected slow RPC log can be logger. > for `logSlowRPCThresholdMs`, we can support dynamic refresh to facilitate > adjustments based on the actual operating conditions of the hdfs cluster. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
