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.
