[VOTE] FLIP-103: Better TM/JM Log Display

[Yadong Xie]

Hi all

I want to start the vote for FLIP-103, which proposes to provide better
user log display UI in task manager and job manager.

To help everyone better understand the proposal, we spent some efforts on
making an online POC

Task manager:

previous web:
http://101.132.122.69:8081/#/task-manager/6df6c5f37b2bff125dbc3a7388128559/logs
POC web:
http://101.132.122.69:8081/web/#/task-manager/6df6c5f37b2bff125dbc3a7388128559/log

Job manager:

previous web: http://101.132.122.69:8081/#/job-manager/logs
POC web: http://101.132.122.69:8081/web/#/job-manager/log


The vote will last for at least 72 hours, following the consensus voting
process.

FLIP wiki:
https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=147427143

Discussion thread:
http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/DISCUSS-FLIP-75-Flink-Web-UI-Improvement-Proposal-td33540.html

Thanks,

Yadong

The log files list are shown in the new design. I like the idea. Since the
user defined logs(e.g. my-log.file)
could be found here now.


Best,
Yang

I like the ideas of having a list of all log files, and make them
downloadable.

Thank you~

It lists all log files, the user could see the GC log.

A minor question: I didn't find the GC log in the POC web. Is it only
generated when some configuration is enabled?

Best,
Jark

Hi Jark,

The GC log is not enabled by default. If the users want, he/she should
configure it by the following config option.
env.java.opts.jobmanager: -XX:+PrintGCDetails -XX:+PrintGCDateStamps
-Xloggc:/opt/flink/log/jobmanager-gc.log -XX:+UseGCLogFileRotation
-XX:NumberOfGCLogFiles=2 -XX:GCLogFileSize=512M

Best,
Yang

Hi Jark,

The GC log is not enabled by default. If the users want, he/she should
configure it by the following config option.
env.java.opts.jobmanager: -XX:+PrintGCDetails -XX:+PrintGCDateStamps

A minor question: I didn't find the GC log in the POC web. Is it only

The log files list are shown in the new design. I like the
idea.
Since
the

Hi all

I want to start the vote for FLIP-103, which proposes to
provide
better
user log display UI in task manager and job manager.

To help everyone better understand the proposal, we spent
some
efforts
on
making an online POC

Task manager:

previous web:







http://101.132.122.69:8081/#/task-manager/6df6c5f37b2bff125dbc3a7388128559/logs
POC web:







http://101.132.122.69:8081/web/#/task-manager/6df6c5f37b2bff125dbc3a7388128559/log

Job manager:

previous web: http://101.132.122.69:8081/#/job-manager/logs
POC web: http://101.132.122.69:8081/web/#/job-manager/log


The vote will last for at least 72 hours, following the
consensus
voting
process.

FLIP wiki:

It can be very helpful to check GC state when GC logging is enabled.

Thanks all for the votes.

So far, we have

- 4 binding +1 votes (Kurt, Jark, jincheng, Zhu Zhu)
- 5 non-binding +1 votes (Yang Wang, Xintong Song, lining, Yangze, zhenya)
- No -1 votes

The voting time has past and there are enough +1 votes to consider the
FLIP-103 approved.
Thank you all.

Hi Till

In addition to the front end, the FLIP-103 would also include some rest API
changes.
Could you assign one PMC or committer to help us review the pull request
and drive this FLIP forward?
We will start to create PR as soon as possible, thanks!

[Yadong Xie]

Hi all

sorry for we have an issue that was not discovered in advance

When users run multiple standalone TMs on the same host, the JM log list
may confuse the users since all JM and TM logs are stored in the same
folder, and they will appear on the same list.

I have a discussion with Gary and Lining, a temporary workaround could be:
show the main log and stdout file by default and make the log list a
separate page.

This workaround would allow us to roll out the feature while not changing
existing behavior.

What do you think?
