IBM Tivoli Monitoring: Implementation and Performance Optimization for Large Scale Environments

Chapter 7. Deploying IBM Tivoli Monitoring agents in a large scale environment 241

7. A start command is invoked via an SQL1 call to the OS agent, to start the

monitoring agent. The command waits for the status feedback

asynchronously.

There are three main parameters that might affect the performance of the

deployment process. These parameters are set on the monitoring server’s

KBBENV (or kbbenv.ini) files.

򐂰 DEPLOYQUEUESIZE

This is the maximum number of requests that the request queue on the agent

deployment controller will handle. It has a default of 100, if you do not

override with a specific setting.

Note that OS agent deployments that are performed with createNode do not

use this setting, because these deployments do not go through the

deployment controller. Instead, they communicate directly with the target

system. This parameter only works when deploying application agents via

addSystem.

򐂰 DEPLOYTHREADPOOLSIZE

This is the number of threads that are available to the deployment controller.

The default is 10 unless otherwise overridden. It controls how many active

asynchronous threads the deployment controller uses to push the depot files

down with.

򐂰 DATACHUNKSIZE

This is the size of the data chunk that will be passed to RPC for transfer. The

default is 500 KB unless it is overridden. If you have sufficient network

bandwidth, you might want to increase this value, but be careful if this

bandwidth is shared with critical production applications (especially when the

deployment is done during business hours).

7.4 Considerations for installing OS and non-OS agents

remotely

As mentioned earlier, you can install both OS and non-OS agents remotely, but

there are some differences.

7.4.1 OS agents

OS agents must be installed before you can install a non-OS agent (such as a

DB2 monitoring agent) on a target computer. OS agents can be installed

remotely using the command line interface (CLI).
