Varun Vasudev updated YARN-2901: -------------------------------- Attachment: Exception expanded.jpg Exception collapsed.png [~leftnoteasy] {quote} 1) Can we have a separate table to show recent X warnings/error in addition to "most frequent warnings/errors"? {quote} You can sort by date in the table. By default, the table is sorted to show you the most recent errors/warnings. The counts are just a collapse so that if you have the same error occurring over and over again, it doesn't fill up the table. {quote} 2) Is it possible to get exception stack trace as a part of the warnings/errors page. Sometimes stack trace is not a part of warn/error, but they're also very useful to troubleshooting issues. {quote} Uploaded a screenshots of what an exception collapsed and expanded will look like. Can you let me know if it looks ok? The different colors are some issue with the exporting. > Add errors and warning stats to RM, NM web UI > --------------------------------------------- > > Key: YARN-2901 > URL: https://issues.apache.org/jira/browse/YARN-2901 > Project: Hadoop YARN > Issue Type: New Feature > Components: nodemanager, resourcemanager > Reporter: Varun Vasudev > Assignee: Varun Vasudev > Attachments: Exception collapsed.png, Exception expanded.jpg, Screen > Shot 2015-03-19 at 7.40.02 PM.png, apache-yarn-2901.0.patch > > > It would be really useful to have statistics on the number of errors and > warnings in the RM and NM web UI. I'm thinking about - > 1. The number of errors and warnings in the past 5 min/1 hour/12 hours/day > 2. The top 'n'(20?) most common exceptions in the past 5 min/1 hour/12 > hours/day > By errors and warnings I'm referring to the log level. > I suspect we can probably achieve this by writing a custom appender?(I'm open > to suggestions on alternate mechanisms for implementing this). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
