BMC PATROL Agent is a core component of the Infrastructure Management architecture that monitors and manages the distributed environment.

BMC PATROL Agent overview

A BMC PATROL Agent performs the following tasks:

  • Runs commands to collect information either locally or remotely; the information is collected according to the applications and parameters defined in KMs.
  • Acts as a service provider for event and data management for BMC TrueSight Infrastructure Management Server
  • Interpret data by using defined rules
  • Loads specified KMs at start-up, runs commands, and updates configuration information
  • Stores information locally

For information about BMC PATROL Agent, see the BMC PATROL Agent Reference Manual.

Configuring BMC PATROL Agent for Infrastructure Management

BMC PATROL Agent is configured for Infrastructure Management using Central Monitoring Administration.

Central Monitoring Administration is a web-based administration interface used to perform the following tasks:

  • Create BMC PATROL Agent installation packages that contain BMC PATROL Agent and the supported monitoring solutions
  • Configure BMC PATROL Agents for monitoring
  • Add Integration Services to BMC TrueSight Infrastructure Management Server
  • Create Integration Service clusters
  • Configure blackouts on BMC PATROL Agents
  • Create time frames for blackout
  • Configure the /AgentSetup/integration/integrationServices variable on the BMC PATROL Agent. The BMC PATROL Agent uses this variable to connect to the Integration Service.
  • Download and install Integration Service and the remote Administration Console
  • Add or update monitoring solutions in the monitoring repository

BMC PATROL Agent installation packages are silent installation files that contain your installation preferences for monitoring solutions and components. Central Monitoring Administration uses policies to configure monitoring solutions and thresholds and to copy baselines.

With Central Monitoring Administration, administrators select monitor installation components, such as the BMC PATROL Agent and monitoring solutions, from the Infrastructure Management Central Monitoring Repository to create an installation package. The components can then be installed together using the installation package. You can reuse the installation packages, or deploy the packages to multiple computers.

Through Central Monitoring Administration, administrators define and manage policies. A policy is a set of actions to perform, such as configuring monitoring solutions on BMC PATROL Agents, creating thresholds on Child Servers, and copying baselines between similar instances of child servers. Policies can also be used to assign devices and monitor instances to User Groups which can be used for access control.

A policy is applied to the BMC PATROL Agents based on the conditions such as agent name, agent port, agent version, agent tag, and so on. If an agent matches the conditions defined in multiple policies, then Central Monitoring Administration combines the configuration across the policies and applies it to the agent.

Event and data flow architecture of BMC PATROL Agent for Infrastructure Management

The BMC PATROL Agent reads the tag information from the following pconfig variable:

/AgentSetup/Identification/Tags/Tag/tagName, where tagName is the name of the tag

The BMC PATROL Agent sends the information to the Integration Service, which passes the information to Central Monitoring Administration. Central Monitoring Administration evaluates policies that match the tags or the agent properties, determines the final configuration to be applied, and sends the configuration information back to the agent. Monitoring is based on the configuration information received by the agent, under /AgentSetup/preloadedKMs pconfig variable. It contains the list of .kml files that must be loaded for the corresponding configuration.

The BMC PATROL Agent initiates a configuration request after certain events, such as agent installation, agent restart, agent auto-connection with Integration Service, or changing a tag on the agent. If no policy matches the agent conditions, the agent does not receive configuration information. The agent does not receive the configuration until a matching policy is created.

If a policy is created or updated, changes are pushed from Central Monitoring Administration, via the Integration Service, to BMC PATROL Agents, and the /AgentSetup/preloadedKMs pconfig variable is received as a part of configuration.

The monitoring solutions configuration is stored under /ConfigData pconfig branch. The pconfig variables received by BMC PATROL Agent from Central Monitoring Administration are with REPLACE request. For the configuration under /ConfigData, only the difference between the configuration received and the configuration that the agent contains is applied. If some configuration is not received, it is considered to be deleted and is deleted from /ConfigData. For the configuration under /AgentSetup, it is applied directly.

For /AgentSetup configurations, the variables under the /ConfigData pconfig branch take precedence.

Warning

You should not manually update any variables and values under /ConfigData. The variables and values are only for internal use.
