[jira] [Commented] (FLINK-10002) WebUI shows logs unfriendly,
especially when the amount of logs is large
[ https://issues.apache.org/jira/browse/FLINK-10002?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16744944#comment-16744944 ]
zhangxinyu commented on FLINK-10002:
------------------------------------
[~lining] Did you test it? If the log file length is smaller than the input number, it's expected to return the data from offset 0 to the length of the log file.
Could you please show me the error?

> When a streaming job run for a long time, the amount of logs may be very large. The current WebUI shows all content of logs. It will cost much time to download logs from task managers. and the browser cannot display the logs.
> Therefore, I suggest that Flink uses DailyRollingAppender to split logs by default, and task manager provides an API that can get logs based on a parameter of time interval. In this way WebUI can display logs based on time interval.
