Monitoring, Version 6.2
Before installing any Tivoli Monitoring agents, you must first install the Tivoli Monitoring infrastructure components, which include the hub monitoring server, portal server, remote monitoring server, Warehouse Proxy agents, and Summarization and Pruning agent.
For the first phase of your deployment, deploy a relatively small environment, which provides you with the opportunity to test your production environment and ensure that it is running smoothly. Deploy the hub monitoring server and only two remote monitoring servers initially. The remote monitoring servers can successfully monitor up to 1500 agents, so using two remote monitoring servers during your initial deployment is not a problem. Firewall considerations might necessitate additional remote monitoring servers.
If you plan to use clustering to achieve a high availability configuration, configure the cluster before connecting any agents. Otherwise, it is necessary to reconfigure the agents to connect to the cluster rather than connecting to one of the nodes in the cluster. For information on setting up the hub monitoring server and portal server in an OS Cluster search the following text strings to find solutions in Tivoli® Open Process Automation Library (OPAL):
Because the installation of application agent support on the monitoring server and portal server requires them to be recycled, install the application support on the monitoring server, portal server, and portal client for all agents that you expect to deploy in the next six to nine months. This likely includes the IBM Tivoli Monitoring for Databases, IBM Tivoli Monitoring for Messaging and Collaboration, ITCAM for SOA and any other products you plan to implement.
During the initial installation phase, install the Warehouse Proxy agent and Summarization and Pruning agent, but do not begin using them until after you have successfully deployed your first 50 agents. Installing in this way gives you an opportunity to assess the health of your environment before adding to the complexity of your environment.
