Direct, Indirect, Agentless Data Collection, and Two-phase Data Collection

When you register computers, you have the option to select the type of collection. The most complete is direct collection. The direct collection is an option from the Managed computer. Using direct collection, you can collect the following information:

• Windows computers for:
  • Logical Volumes
  • Physical Disks
  • Partitions
  • Quota
  • Owners
  • Security Groups
  • Shares
  • HBAs
  • HBA Ports
  • HBA Ports Performance
• UNIX for:
  • Logical Volumes
  • Volume Groups
  • Physical Disks
  • Partitions
  • Owners
  • Security Groups
  • Mounted Drives
  • HBAs
  • HBA Ports
  • HBA Ports Performance
• NetWare for:
  • Logical Volumes
  • Owners
  • Security groups

If you register a computer to use direct collection, you can use file scanning search.

Agentless collection means CA SRM does not install the agent on the computer you want to register. This type of collection collects information about Windows computers for:

• Logical Volumes
• Physical Disks
• Partitions

When you register a computer as agentless, you cannot use file scanning search.

Indirect collection is a way to collect data from a computer with an operating system CA SRM does not currently support. Proxy collector does the indirect collection. This type of collection collects information about:

• Windows computers for Logical Volumes
• UNIX computers for Logical Volumes

When you register a computer using indirect collection, you can use file scanning search.

The two-phase data collection is done using SMI-S 1.02 and 1.1. Two-phase data collection means CA SRM executes the collected raw data on a proxy server without any application server database access and update database executed on the application server.

• Independent Data Collection-Using a proxy server, raw data is collected and executed on the managed server without any application server database access.
• Local Data Collection-The File Transfer Agents pulls the data from the managed object and updates and executes the collected data on the application server database.

The advantages of two-phased data collection are:

• Decentralized management
• Detached and local data collection
