--------------------------------------
Summary: Add timestamp/hostname to JSON output from Web UI
endpoints
Key: IMPALA-11881
URL: https://issues.apache.org/jira/browse/IMPALA-11881
Project: IMPALA
Issue Type: Improvement
Components: Backend
Affects Versions: Impala 4.3.0
Reporter: Joe McDonnell
Sometimes it is useful to periodically get the JSON output from some of the
WebUI endpoints (e.g. rpcz or memz). If there are periodic samples from several
nodes, then there is a lot of analysis that can be done via scripting.
Adding some information that ties the JSON output to a specific time and node
would make the processing easier. Adding the timestamp of generation and the
hostname that generated it would keep the JSON files distinct when writing
scripts.
