What is a Tomcat cluster?

The Cluster element is used by Tomcat to provide context attribute replication, WAR deployment, and session replication, and can be nested within either the Engine or the Host element. The Manager, Channel, Valve, Deployer, and ClusterListener elements are nested inside of it. More information on these elements and how they are used can be found on Apache's Tomcat Configuration page. Although this element is highly configurable, the default configuration is generally enough to meet most users' needs.

What is HTTP/1.1 connector?

This element represents an HTTP/1.1 Connector , and provides Catalina with stand-alone web server functionality. This means that in addition to executing servlets and JSP pages, Catalina is able to listen to specific TCP ports for requests. Each Connector you define represents a single TCP port Catalina should listen to for HTTP requests. When configuring your HTTP connectors, pay close attention to the "minSpareThreads", "maxThreads", and "acceptCount" attributes. The "maxThreads" attribute is of particular importance. This attribute controls the maximum number of threads that can be created to handle requests exceeding the number of available threads. Setting this value too low will cause requests to stack inside the server socket, which will begin refusing connections once it is full. Comprehensive testing will help you avoid this problem.

What is a context element in Tomcat?

This element represents a single web application, and contains path information for directing requests to the appropriate application resources. When Catalina receives a request, it attempts to match the longest URI to the context path of a given Context until it finds the correct element to serve the request. The Context element can have a maximum of one nested instance per element of the utility elements Loader, Manager, Realm, Resources, and WatchedResource. Although Tomcat allows you to define Contexts within "TOMCAT-HOME/conf/server.xml", this should generally be avoided, as these central configuration settings cannot be reloaded without restarting Tomcat, which makes editing Context attributes more invasive than necessary.

What is a nesting connector in Catalina?

By nesting one Connect or (or multiple Connect ors) within a Service tag, you allow Catalina to forward requests from these ports to a single Engine component for processing. Tomcat allows you to define both HTTP and AJP connectors.

What is Apache Tomcat?

Apache tomcat is an open source web container . Ø Apache tomcat is a webserver and can easy to deploy our web application on server. Specially java applications. Ø In the Java world, they decided to create small pieces of code to serve application requests, without having to worry about how HTTP requests/responses work. Ø The biggest advantage in a Java-centric environment: It’s open source , lots of people know how to work with it, and you can change something that you find doesn't work for whatever reason. Other advantages: It's smaller than some other Java-based solutions. If you’re deploying Servlets, going lightweight and small is a good thing. Ø Tomcat uses several Java EE specifications such as Java Servlet, (JSP), EL, and WebSocket, and provides a “pure Java” HTTP web server environment for Java concept to run

What is an extended access valve?

The Extended Access Log Valve extends the Access Log Valve class, and so uses the same self-contained logging logic. This means it implements many of the same file handling attributes. The main difference to the standard AccessLogValve is that ExtendedAccessLogValve creates log files which conform to the Working Draft for the Extended Log File Format defined by the W3C.

What is access log valve?

The Access Log Valve creates log files in the same format as those created by standard web servers. These logs can later be analyzed by standard log analysis tools to track page hit counts, user session activity, and so on. This Valve uses self-contained logic to write its log files, which can be automatically rolled over at midnight each day. (The essential requirement for access logging is to handle a large continuous stream of data with low overhead. This Valve does not use Apache Commons Logging, thus avoiding additional overhead and potentially complex configuration).

How to enable Tomcat access log?

Uncommenting the entry will enable an access log that contains fields equivalent to a "common" log file format from Apache. The defaults for the valve will result in a file named "localhost_access_log" followed by the date, followed by a ".txt" file extension. IP addresses will be logged, not hostnames and log file will be written into the $ {tomcat.home}/logs directory. The fields present in the log file using a common format are:

Does RemoteIP Valve log IP address?

The main problem here, that RemoteIP Valve does take care of, is that you'll only get the X-Forwarded- For address in the logs. If you hit the app server directly, bypassing the device that is inserting the X-Forwarded-For header in the request, you won't get an IP address logged. You will still log a request—you just will not know where it came from.

Can Tomcat 7 use remote IP?

If you are running a version of tomcat greater than version 6.0.21 or tomcat 7, you can take advantage of the new Remote IP Valve. For access logging, the nice thing about this valve is that it will swap the client IP with an IP address passed with the X-Forwarded-For header—automatically—if an IP address is passed in the X-Forwarded-For header. Loading it is pretty easy. Just add the org.apache.catalina.valves.RemoteIpValve to your server.xml before your AccessLogValve declaration. For example:

Is Tomcat ok to log?

The common log format is ok but changing the pattern to combined adds the User-Agent (browser or robot type) and the referring web site and URI.
