Features:
When using real-time data, the front-end can perform real-time data calculation and processing through simple mouse clicks and drags. So when doing real-time data analysis, if you encounter some errors, how should you troubleshoot? In this chapter, we introduce the configuration and viewing of real-time data execution logs;
Applicable people: administrators;
Go to , and click the Global Settings button "Manage > Intelligent Operations > Platform Log".
At the system log level, you can set the log level (the real-time data is also set here), including DEBUG, INFO, WARN, ERROR, FATAL, and the default is ERROR. As shown below:
level
illustrate
DEBUG
Point out fine-grained information events, very helpful for debugging applications, mainly used to print some running information during development
INFO
Messages highlight how the application is running at a coarse-grained level. Print some information that you are interested in or important. This can be used in the production environment to output some important information about the operation of the program, but it cannot be abused to avoid printing too many logs
WARN
Indicates potential situations, some messages are not error messages, but also some hints for programmers
ERROR
It is pointed out that although an error event occurs, it still does not affect the continued operation of the system. Print error and exception information, if you don't want to output too many logs, you can use this level
FATAL
Point out that each serious error event will cause the application to exit. This level counts high, major errors, this level can directly stop the program
Log path: %FineBI%/logs
Log name: fanruan.log (or fanruan.log.date)
Log example:
log level: INFO;
Log keyword: the preview sql is;
log level: DEBUG;
Log keyword: direct.sql.table.field.sql;
log key:
sql create: time-consuming to convert sql;
sql execute/slice sql execute: time-consuming sql query;
sql foreach result/slice sql foreach result: time-consuming sql fetching;
