-----------------------------------
Summary: Add metrics for HTTP Server
Key: HADOOP-8905
URL: https://issues.apache.org/jira/browse/HADOOP-8905
Project: Hadoop Common
Issue Type: Improvement
Components: metrics
Affects Versions: 3.0.0
Reporter: Todd Lipcon
Currently we don't expose any metrics about the HTTP server. It would be useful
to be able to monitor the following:
- Number of threads currently actively serving servlet requests
- Total number of requests served
- Perhaps break down time/count by endpoint (eg /jmx, /conf, various JSPs)
This becomes more important as http-based protocols like webhdfs become more
common
