How to configure and use Glowroot Application Performance Management (APM) tool in Liferay

Overview


Liferay Portal 7.4 GA100 comes bundled with a brand new feature - Glowroot APM, a tool for monitoring and management of performance and availability of software applications. It provides a lot of features, such as:
  • Trace capture for slow requests and errors;
  • Continuous profiling (with very handy filtering);
  • SQL capture and aggregation;
  • Response time breakdown charts;
  • Service call capture and aggregation;
  • Responsive UI with mobile support;
  • Configurable alerting
and many others. 
Glowroot is easy-to-use and very low overhead.
By default, it's disabled in Liferay installation.
This blog explains how to enable and use Glowroot APM. 

Starting and using Glowroot


Glowroot can be enabled during portal startup by passing "glowroot run" argument to catalina.sh startup script:


Once portal is started - you can sign in as administrator (by default: test@liferay.com / test), and navigate to the Glowroot URL:


On the homepage you'll see a dashboard with web transactions analytics: 

For each web transaction (URL) in the left sidebar you can get more detailed analytics on:
  • Response time; 
  • Slow Traces;
  • Queries;
  • Service Calls;
  • Thread Profile.
For "Slow Traces" ones you can get all details about request processing: execution time breakdown, affected classes and JSPs, database queries, etc.:


This information should help with identifying and fixing performance issues in Liferay.

Enjoy 😏
