Monitoring Liferay with New Relic

Everyone who run, tests or maintains a Liferay environment needs to know if it performs well. ‘Performing well’ is a broad statement, that can range from low-level OS measurements such as memory allocation and CPU usage all the way up to the speed a page renders in a browser – the stuff that customers complain about, and is hard to reproduce and measure.

New Relic provides this insight – from OS to browser – with their cloud based application performance management tools. Setting up New Relic for Liferay is quite easy, but as always with Liferay, there are a few pitfalls. This blog post will guide you through the setup in a few steps. Read more…

OpenSSO and Secure Ticket Service (STS)

For one of our customers we’ve been working on securing their web services with Secure Ticket Service (STS). The setup involves a Liferay Portal that authenticates the users using OpenSSO Express 8.
