performance monitoring tools for multi-tenant web application

We have a need to monitor performance of our java web app. We are looking for some tolls which can help us with this task. The major difficulty is that we are SaaS provider with multi-tenant server architecture with hundreds of customers running on the same hardware. So far we tried commercial products like DynaTrace and Coradinat but unfortunately they don't get the job done so far. What we need is a simple report which would tell us if we had performance problems on each customer site in a specified period of time. Mostly it will be response time per customer but also we will need some more specifics base开发者_JAVA百科d on the URLs.

please let me know if someone had any experience with setting up such monitoring.

Thanks!

Take a look at stagemonitor. It is an open source java web application performance monitoring library capable of multi-tenancy. It captures response time metrics, JVM metrics, request details and more. The overhead is very low. It uses the great timeseries database graphite that automatically downsamples historical datapoints which leads to a low storage overhead.

Here is a screenshot. You can find more on the project site.

HypericHQ is nice for this because, being written in Java itself, it integrates quite nicely with all the MBean properties already exposed on your APP server. You can set up administrator alerts/charts based on JVM properties/app server MBean properties that most non-Java tools can't get at.

On the downside, it does like to run a relatively heavy (as these things go) agent on your server.
