suyue closed IOTDB-116. ----------------------- > Performance statistic of IOTDB > ------------------------------ > > Key: IOTDB-116 > URL: https://issues.apache.org/jira/browse/IOTDB-116 > Project: Apache IoTDB > Issue Type: New Feature > Reporter: suyue > Priority: Minor > Labels: pull-request-available > Attachments: image-2019-06-14-09-33-08-958.png, > image-2019-06-17-17-08-32-776.png, image.png > > Time Spent: 20m > Remaining Estimate: 0h > > In order to better grasp the performance of database in practical > application, we add a module to count the time-consuming of each operation. > This module can statistic the avg time-consuming of each operation and the > proportion of each operation fall into a time range.A output example is in > below. This module uses asynchronous operation to reduce the impact on the > normal speed of the database.The queue size is controlled by a param in > iotdb-engine.properties, which is 'performance_stat_memory_in_kb'. The > output is in log_measure.log file. > !image-2019-06-14-09-33-08-958.png! -- This message was sent by Atlassian Jira (v8.3.4#803005)
