Performance Optimization - HBase Design Patterns - page 124

Here is a sample screenshot of the JMX metrics via the web UI:
Here's a quick example of how to programmatically retrieve these metrics using curl :
$ curl 'localhost:60010/jmx'
Since this is a web service, we can write a script/application in any language (Java,
Python, or Ruby) to retrieve and inspect the metrics.
Summary
In this chapter, you learned how to push the performance of our HBase applications
up. We looked at how to effectively load a large amount of data into HBase. You
also learned about benchmarking and monitoring HBase and saw tips on how to
do high-performing reads/writes.
With this, we conclude the topic. We hope it's been a fun journey for you. Please visit
the topic's site, http://hbasedesignpatterns.com , and on the GitHub repository,
https://github.com/elephantscale/hbase-book . While the topic itself cannot be
updated (even though some topics can; you can check here: http://bit.ly/1Ec1V7H ) ,
we plan to keep the repository updated with fixes and more examples.
