This section describes the best practices and recommendations to be used for BMC ProactiveNet Central Monitoring Administration.
BMC recommends implementing one of the following two choices of architectural deployments for Central Monitoring Administration.
The first choice is to implement a single Central Monitoring Administration instance for all environments including development, test, and production.
It requires less infrastructure nodes and components. Only a single staging Integration Service host is needed. Only a single Central Monitoring Administration instance is used.
This many not be supported in some sites where all the necessary connections in the development, test, and production environments are not available or allowed to be connected over the network.
Due to the powerful ease of use, it is easier for administrators to make mistakes applying policies unintentionally to production. However, this can be managed.
The second choice is to implement a separate Central Monitoring Administration instance each in the development, test, and production environments.
Creating, testing, and deploying monitoring policies into production require more manual effort because you have to export or import policy data from the development to the test environment and from the test to the production environment.
Policies can get out of sync across development, test, and production environments if not managed properly. Keeping them up-to-date is more of a manual process supported by the export/import utility.
It requires more infrastructure nodes and components. The development, test, and production environments must each have a dedicated staging Integration Service host and a dedicated instance of Central Monitoring Administration.
Neither method supports seamless creation, testing, production, deployment, and deletion of updates for existing policies. Updates and deletion of existing policies that are already in production must be created, tested, and populated to production leveraging the policy export/import capability. For more information see Staging and policy management for development, test, and production best practices.
In all scenarios, Central Monitoring Administration communicates thorough the agent controller process on the BMC ProactiveNet Server(s) to the Integration Service nodes.
These implementation architecture options are not installation options. The Central Monitoring Administration components are the same. These two implementation architecture options are just choices in how you install Central Monitoring Administration instances and connect them to the various BMC ProactiveNet Servers.
The following diagram illustrates the high-level architecture for a single Central Monitoring Administration instance in a multiple BMC ProactiveNet Server environment including development, test, and production.
In the single Central Monitoring Administration architecture, a single staging Integration Service node is used in the agent deployment process for all agents. All BMC ProactiveNet Servers leverage the single Central Monitoring Administration instance for the entire policy management.
The following diagram illustrates the high-level architecture for multiple Central Monitoring Administration instances in the development, test, and production environments.
In this architecture, each environment has its own dedicated Central Monitoring Administration instance and a staging Integration Service. All policy application between environments is supported by the policy export/import utility.
In most BMC ProactiveNet multiple server environments, Central Monitoring Administration is installed automatically when the BMC ProactiveNet Central Server is installed. However, it is possible to install Central Monitoring Administration when you are installing a standalone BMC ProactiveNet Server and then manually register the additional BMC ProactiveNet Servers with Central Monitoring Administration after the installation.
The following are reasons for installing Central Monitoring Administration on standalone BMC ProactiveNet Servers and not leveraging the Central Server capability:
The following diagram illustrates the default ports and connectivity that support Central Monitoring Administration across multiple BMC ProactiveNet Servers. The arrows indicate the direction from which the connections are established.
The detailed architecture applies to both, single server deployment and multiple server deployment.
