Chapter 1. Overview of the agent
The IBM Tivoli Monitoring for Virtual Environments Agent for Linux Kernel-based Virtual Machines
(product code V1) provides you with the capability to monitor Linux Kernel-based Virtual Machines.
IBM® Tivoli® Monitoring is the base software for the Linux Kernel-based Virtual Machines agent. The
Linux Kernel-based Virtual Machines agent monitors
IBM Tivoli Monitoring
IBM Tivoli Monitoring provides a way to monitor the availability and performance of all the systems in
your enterprise from one or several designated workstations. It also provides useful historical data that
you can use to track trends and to troubleshoot system problems.
You can use IBM Tivoli Monitoring to achieve the following tasks:
v Monitor for alerts on the systems that you are managing by using predefined situations or custom
situations.
v Establish your own performance thresholds.
v Trace the causes leading to an alert.
v Gather comprehensive data about system conditions.
v Use policies to take actions, schedule work, and automate manual tasks.
The Tivoli Enterprise Portal is the interface for IBM Tivoli Monitoring products. You can use the
consolidated view of your environment as seen in the Tivoli Enterprise Portal to monitor and resolve
performance issues throughout the enterprise.
See the IBM Tivoli Monitoring publications listed in “Prerequisite publications” on page 125 for complete
information about IBM Tivoli Monitoring and the Tivoli Enterprise Portal.
Functions of the monitoring agent
Display health and performance of Linux KVM host hypervisor systems and guest virtual machines
You can use the Linux Kernel-based Virtual Machines agent to visualize host capacity and virtual
machine consumption in Linux KVM systems.

Components of the IBM Tivoli Monitoring environment
After you install and set up the Linux Kernel-based Virtual Machines agent, you have an environment
that contains the client, server, and monitoring agent implementation for Tivoli Monitoring.
This Tivoli Monitoring environment contains the following components:
Tivoli Enterprise Portal client
The portal has a user interface based on Java™ for viewing and monitoring your enterprise.
Tivoli Enterprise Portal Server
The portal server is placed between the client and the Tivoli Enterprise Monitoring Server and
enables retrieval, manipulation, and analysis of data from the monitoring agents. The Tivoli
Enterprise Portal Server is the central repository for all user data.
Tivoli Enterprise Monitoring Server
The monitoring server acts as a collection and control point for alerts received from the
monitoring agents, and collects their performance and availability data. The Tivoli Enterprise
Monitoring Server is also a repository for historical data.
