ASF GitHub Bot commented on AIRFLOW-620:
----------------------------------------

phani8996 opened a new pull request #3992: [AIRFLOW-620] Feature to tail custom number of
logs instead of rendering whole log
URL: https://github.com/apache/incubator-airflow/pull/3992
 
 
   Dear Airflow Maintainers,
   
   This is a change in the way we render logs. This PR will give a dropdown of number of lines
to be tailed with a refresh button. On refresh webserver fetch selected number of lines from
local worker logs or remote worker logs. On can toggle this feature using config variable
tail_logs in webserver, default number of lines to tail via config variable num_lines in webserver
and items in dropdown can be controlled via config variable tail_lines_list in webserver in
csv format
   
   Please accept this PR that addresses the following issues:
   https://issues.apache.org/jira/browse/AIRFLOW-620
   
   Testing Done:
   
   Manually tested on all major browsers.
   This will add a dropdown of number of lines to be tailed and refresh button to get latest
logs instead of refreshing the whole page.

> As of now to see the latest logs of a task instance one has to refresh the whole page,
which is time consuming. It'll be great if just logs can be re-fetched from backend.
