Troubleshoot

It is no more hassle to look for logs of Apache Tomcat one by one. All logs are within the same user interface. 

Finding Leaks

Finding Leaks functionality in ManageCat enables you to see if a web application has caused a memory leak during stop, reloading or undeployment.

Platform MBeans

With ManageCat, you can easily inspect Memory MBeans, Thread MBeans, Operating System MBeans and Runtime MBeans from a single location.

Memory MBeans

Memory MBeans functionality provides information about memory consumption, memory pools, and garbage collection statistics by accessing the memory related system MBeans.

Thread MBeans

Thread MBeans functionality provides information about current JVM threads information by accessing the Thread MBeans. The Threading MBeans also provides several useful operations, such as 'findMonitorDeadlockedThreads','getThreadInfo','getThreadCpuTime' etc.

Operating System MBeans

Operating System MBeans functionality provides information about certain OS resource information such as, 'process CPU time','amount of total and free physical memory','amount of committed virtual memory','amount of total and free swap space', 'number of open file descriptions' etc. 

Runtime MBeans

Runtime MBeans functionality provides information about current Java Virtual Machine. Runtime MBeans provides several convenient methods for accessing system properties about the Java virtual machine, such as 'name representing the running Java virtual machine','Java virtual machine implementation name','Java virtual machine specification vendor' etc. 

Tomcat Runtime Threads

It is possible to view all JVM Threads which reside in currently connected server in ManageCat platform. You can see detailed information about the selected thread. Moreover, Thread Stacktrace can be also viewed with all the details.

Tomcat Logs

Viewing Tomcat Logs in ManageCat enables you to inspect content of the log files of the current connected server without leaving the platform. All Tomcat logs can be managed easily. All these log files are located in the logs directory of the Tomcat server.

System Logs

Viewing System Logs in ManageCat enables to you inspect content of the System Log Files, i.e 'System.error' and 'System.out' logs without leaving the platform. All system logs can be managed easily.

Application Logs

Viewing Application Logs in ManageCat enables you to inspect content of the log files which are configured per web application context without leaving the platform. Tomcat JULI based loggers and their handlers are also provided per web application context. All application logs are managed easily. You can also inspect LOG4J based loggers and handlers. One of the most important feature is that you can change level of the loggers at runtime without starting the application server.

Metric Events and Alerts

You can define conditions on metrics. When Metric Item Condition evaulates to true, system fires a Metric Item Event object. These events are collected and sent to system administrators by condition alerts. Alerts are actions which are executed by the system after event is fired. Each condition may have alert definitions. Alerts can be one of them Execute Scripts, Sent Email, Log Event etc. In current version of the platform, only Sent Email alerts
are supported. You can also view events from the console view.

Application Class Loaders

ClassLoader Viewer page provides a web application ClassLoader hierarchy. It show s classloaders in a tree hierarchy that root of the tree is Java Bootstrap ClassLoader. In the event of class loader problems, you can easily inspect the each application classloaders.

Application Data Sources

Datasource Viewer Page provides informations about deployed web applications' datasources that are bound to JNDI context of the web application. In this page, you are able to get and set configuration parameters of the datasources. In the event of connection pooling problems, you can easily check configured datasource pool properties and update according to your requirements.
