Performance Monitoring in RTMT Chapter 5 Cisco Unified Real-Time Monitoring Tool Tracing, PerfMon Counters, and Alerts Table 5-43 Cisco Tomcat Connector (continued) Counters ThreadsTotal ThreadsMax ThreadsBusy Counter Description This counter represents the current total number of request processing threads, including available and in-use threads, for the connector. A Tomcat HTTP connector represents an endpoint that receives requests and sends responses. The connector handles HTTP/HTTPS requests and sends HTTP/HTTPS responses that occur when Cisco Unified Communications Manager related windows are accessed. The Secure Socket Layer (SSL) status of the URLs for the web application provides basis for the instance name for each Tomcat HTTP connector. For example, https://:8443 for SSL or http://:8080 for non-SSL. This counter represents the maximum number of request processing threads for the connector. Each incoming request on a Cisco Unified Communications Manager related window requires a thread for the duration of that request. If more simultaneous requests are received than the currently available request processing threads can handle, additional threads will get created up to the configured maximum shown in this counter. If still more simultaneous requests are received, they accumulate within the server socket that the connector created, up to an internally specified maximum number. Any further simultaneous requests will receive connection refused messages until resources are available to process them. A Tomcat HTTP connector represents an endpoint that receives requests and sends responses. The connector handles HTTP/HTTPS requests and sends HTTP/HTTPS responses that occur when Cisco Unified Communications Manager related windows are accessed. The Secure Socket Layer (SSL) status of the URLs for the web application provides basis for the instance name for each Tomcat HTTP connector. For example, https://:8443 for SSL or http://:8080 for non-SSL. This counter represents the current number of busy/in-use request processing threads for the connector. A Tomcat Connector represents an endpoint that receives requests and sends responses. The connector handles HTTP/HTTPS requests and sends HTTP/HTTPS responses that occur when web pages that are related to Cisco Unified Communications Manager are accessed. The Secure Sockets Layer (SSL) status of the URLs for the web application provides the basis for the instance name for each Tomcat connector. For example, https://:8443 for SSL or http://:8080 for non-SSL. Cisco Tomcat JVM The Cisco Tomcat Java Virtual Machine (JVM) object provides information about the Tomcat JVM, which represents, among other things, a pool of common resource memory that Cisco Unified Communications Manager related web applications such as Cisco Unified Communications Manager Administration, Cisco Unified Serviceability, Cisco Unity Connection Administration, and more use. Table 5-44 contains information on the Tomcat JVM counters. 5-60 Cisco Unified Communications Manager Managed Services Guide OL-22523-01
