How Metric Collection Works

IPM performs the following multi-step process to collect metrics.

  1. Uses SSH to access the SVC configuration node in the SVC environment.

  2. Issues cpdump command to each of the non-configuration nodes for the last available statistics file, if the file is not already processed.

    This results in the non-configuration nodes copying performance statistics files to the configuration node.

    NOTE: The cpdump command requires restrictedadmin access or higher. This is the only command that requires administrative access.

  3. Issues SCP commands to download all of the performance statistics files from the configuration node.

  4. Parses the performance statistics files and loads them into the IPM database.
