Caroline Zhou commented on HBASE-25469: --------------------------------------- [~apurtell] [~stack] [~tianjingyun] [~bharathv] [~vjasani] Please take a look. Added a few fields to the rit.jsp page as well as created a new servlet to serve individual RIT information as json (RIT info in one place, can be parsed for metrics). A couple of things to consider/I would like your feedback on: * Any other fields we should add to the json output? (Aggregates like ritCount, ritCountOverThreshold, etc. can be found in AssignmentManager metrics so I didn't include those here.) * Should we include the ability for the json to display only RIT over threshold/RITs grouped by state or server name? I would also like to backport this to branch-1, after master PR is approved. Thanks. > Create RIT servlet in HMaster to track more detailed RIT info not captured in > metrics > ------------------------------------------------------------------------------------- > > Key: HBASE-25469 > URL: https://issues.apache.org/jira/browse/HBASE-25469 > Project: HBase > Issue Type: Improvement > Reporter: Caroline Zhou > Assignee: Caroline Zhou > Priority: Minor > Attachments: Screen Shot 2021-07-27 at 10.34.45.png, Screen Shot > 2021-07-27 at 10.34.53.png > > > In HBase 2.1+, there is a RIT JSP page that was added as part of HBASE-21410. > There are some additional RIT details that would be helpful to have in one > place: > * RIT Start Time > * RIT Duration (ms) > * Server > * Procedure Type > This info can be added to the table under the {{/rit.jsp}} page, and we can > also add a button on that page to view info as JSON, for easy parsing into > metrics, etc. This JSON dump can be served as a servlet. > We may also consider different ways of grouping the JSON results, such as by > state or server name. > !Screen Shot 2021-07-27 at 10.34.45.png! > !Screen Shot 2021-07-27 at 10.34.53.png! -- This message was sent by Atlassian Jira (v8.3.4#803005)
