Server Planning

The first step in planning your environment is to determine how many CA Enterprise Log Manager servers you need and what role each server will perform. Roles include:

• Management

  Stores predefined and user-defined content and configurations. Also authenticates users and authorizes feature access.

• Collection

  Receives event logs from its agents; refines events.

• Correlation

  Receives event logs from agents or collection servers; filters events and creates incidents according to its applied correlation rules.

• Reporting

  Processes queries on collected events, both on-demand queries and reports and also scheduled alerts and reports.

• Restore point

  Receives restored event log databases for investigation of past events

The first server you install is the management server; this server can perform other roles as well. You can have only one management server in a single CA Enterprise Log Manager network. Every CA Enterprise Log Manager network must have one management server.

Possible architectures include:

• Single-server system, where the management server performs all the other roles
• Two-server system, where the management server performs all roles but collection. Collection is performed by a server dedicated to this role.
• Multiple-server system, where each server is dedicated to a single role.

Details on server roles and architectures follow.
