IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1
Managing Server
The Managing Server is a distinct component of ITCAM for Application Diagnostics. It communicates to the data collectors within the WebSphere and J2EE Agents, and provides detailed diagnostic information through its user interface. You can choose not to install the Managing Server.
The Managing Server consists of the following components:
kernel Controls the Managing Server...
- Registers components as they join
- Periodically renews connections and registrations with components and data collectors
- Collects server and component availability information
There can be an additional copy of the kernel running on a Managing Server to facilitate load balancing, redundancy, and failover. The kernel includes the Watchdog, a lightweight component that manages a particular kernel and restarts it if it does not respond.
Visualization Engine Provides the user interface. Can be accessed through Tivoli Enterprise Portal or stand-alone. Requires IBM WAS. Can be installed on the WAS instance that runs the Tivoli Enterprise Portal. Publish Server Receives data from the data collector and processes it for user display. For example, request data is aggregated, producing various statistics. Archive Agent Collects data from the Publish Server and archives it into the database for reporting. Message Dispatcher Sends out e-mails of performance reports and trap actions from the features...
- Performance Analysis and Reporting
- Trap and Alert Management
Global Publish Server Tracks composite requests as they move from one server to another. For example, if a request was initiated on one server, but its processing moves to another server through a Web Services call, the Global Publish Server ensures that the request is still tracked as a single entity.
The Managing Server also uses a database on IBM DB2 or Oracle (the default database ID is octigate). The database that the Managing Server uses can be hosted on a dedicated database server or jointly with the Tivoli Monitoring database.
For environments that include many servers or are distributed among several sites, you can deploy the Managing Server components across multiple hosts. You can also deploy multiple instances of the kernel, Publish Server, and Archive Agent.
