  • Overview of running server instance
  • Java Virtual Machine
  • Current JVM threads and classes
  • JVM Heap and Non-Heap Memory
  • Operating System
  • JVM startup classpath and program arguments

Server Status Information

It is possible to monitor status of Tomcat Connectors, Virtual Hosts and Clusters. All the data is live and refreshed automatically according to the time interval selected.

Tomcat Connectors

Tomcat Connectors page provides detailed information about Apache Tomcat protocol handlers, a.k.a connectors. There can be several protocol handlers that are configured by administrators. In default configuration of Tomcat, only "HTTP" and "AJP" connectors are enabled. 

Virtual Hosts

Virtual Hosts page enables administrators to view current virtual hosts of the Tomcat Server. It is possible to start/stop and add/remove hosts. 

Cluster Status

Cluster Status page lists clusters that current Tomcat Server's engine/s or host/s are joined. You can check the status of all cluster members that use same cluster channel/s with the current server.

When you open the page you will see cluster details of the current server if this server is joined into the cluster. Clustering is supported on Engine or Host level. By engine level, it means that you will support clustering in all virtual hosts of Tomcat, and share the messaging component.

Tomcat Internal Components

Tomcat consists of several different internal components, such as "Service, Engine, Host, Connector, Context, Cluster, Realms, Valves etc.". With Managecat detailed server configuration view, you can inspect all the default and configured parameters of these components.
