Cisco Tomcat Web Application
The Cisco Tomcat Web Application object provides information about how to run Cisco Unified
Communications Manager web applications. The URLs for the web application provide basis for the
instance name for each Tomcat Web Application. For example, Cisco Unified Communications Manager
Administration (https://<IP Address>:8443/ccmadmin) gets identified by ccmadmin, Cisco Unified
Serviceability gets identified by ccmservice, Cisco Unified Communications Manager User Options gets
identified by ccmuser, Cisco Unity Connection Administration (https://<IP Address>:8443/cuadmin)
gets identified by cuadmin, and URLs that do not have an extension, such as https://<IP Address>:8443
or http://<IP Address>:8080), get identified by _root. Table 5-45 contains information on the Tomcat
Web Application counters.
Table 5-44 Tomcat JVM
Counters Counter Description
KBytesMemoryFree This counter represents the amount of free dynamic memory block (heap memory)
in the Tomcat Java Virtual Machine. The dynamic memory block stores all objects
that Tomcat and its web applications, such as Cisco Unified Communications
Manager Administration, Cisco Unified Serviceability, and Cisco Unity
Connection create. When the amount of free dynamic memory is low, more
memory gets automatically allocated, and total memory size (represented by the
KbytesMemoryTotal counter) increases but only up to the maximum (represented
by the KbytesMemoryMax counter). You can determine the amount of memory in
use by subtracting KBytesMemoryFree from KbytesMemoryTotal.
KBytesMemoryMax This counter represents the amount of free dynamic memory block (heap memory)
in the Tomcat Java Virtual Machine. The dynamic memory block stores all objects
that Tomcat and its web applications, such as Cisco Unified Communications
Manager Administration, Cisco Unified Serviceability, and Cisco Unity
Connection Administration, create.
KBytesMemoryTotal This counter represents the current total dynamic memory block size, including
free and in-use memory, of Tomcat Java Virtual Machine. The dynamic memory
block stores all objects that Tomcat and its web applications, such as Cisco
Unified Communications Manager Administration, Cisco Unified Serviceability,
and Cisco Unity Connection Administration, create.
