Number of hits a tomcat take

[Kmanoj Kumar]

Hi,

I want to find out how many hits the tomcat server is taking per day(count in number) irrespective of the applications deployed on it.
So could you please let me know how to find it.

Thanks you,
Manoj Kumar

Hello Kmanoj,

and welcome to the JavaRanch

Maybe it would be sufficient to configure the Tomcat valve (in the server.xml file) to write an access log and use one of many tools available to analyze the aggregated logs for the time you want to count hits. The Tomcat valve in question is capable of writing access logs in common or combined format just like the famous Apache web server. So there should be enough tools to analyze these logs.

Of course it depends on your requirements. In particular if an access log really provides the information you need.

I use the "management" app - it lets you monitor lots of things such as cumulative number of requests, number of errors, current request threads etc.

I think current versions of Tomcat come with the management app but you have to configure a user role before you can get to it.

A typical Tomcat installation has html-manager-howto.html in the docs directory.

Hello, Kmanoj!

As Marco said, there's an access log Valve that you can turn on for Tomcat and it will record the actual incoming URLs, which is good if you want to start picking apart fine-grained statistics.

For the overall stats, the Manager app will work. Depending on the version of Tomcat, this may need to be downloaded and installed separately from Tomcat. That's partly to keep the main Tomcat download smaller and partly to make Tomcat more secure, I think. To actually use the admin and manager webapps, you not only have to install them but also have to setup application security. By default that's done using a MemoryRealm that reads usernames, roles and password definitiions from the TOMCAT_HOME/conf/tomcat-users.xml file. As supplied the file has a number of commented-out sample entries. You can use them as models to set up your own secured user accounts and roles.
