Web应用程序性能测试监视的工具/建议

Question

I have a web application distributed over different logical and physical layers.

The application is written in php5.3 and uses postgresql version 8.3.

The web front layer has a dedicated machine and is composed of apache htppd 2 webserver running the php engine.

The db layer has another dedicated machine running postgresql. The databases data are stored on machine local file system.

The two layer (web and db) communicate over a 1gbps private network.

I need to setup a execute a performance test on my web application as a whole and the split the test on the single layers (db and web)

Do you know any tool/best practice for such a kind of test?

Any help is appreciated Thanks Regards Alberto

Answer 1

ab is very simple and powerful.

Answer 2

In addition to benchmarking with tools like ab and webbench , you should set up load monitoring tools that watch interface traffic, CPU and disk activity, etc. Pick one of the many RRDTool front-ends and build some graphs, so that you can see what spikes while you run your load test. If you see any curves with flat tops, those are your problem areas. :-)

Check out Cacti , Munin , and others from RRD World .

I like Cacti's user interface, and its auto-discovery is pretty handy. But it can be tricky to keep working, and it has a lot of dependencies. Munin is small, slick and reliable, but requires more hand-holding to configure.

Apache JMeter is also good and produces nice graphs . It can be used to test web applications and databases, amongst others.
