Metrics collected by Monitoring Agent for IBM Cloud Pak System Software

Monitoring Agent for IBM® Cloud Pak System Software collects metrics at the operating system level for monitoring virtual machines in virtual application instances.

This section describes the collected metrics. In the table, note that:
  • For the DISKIO and DISK categories, The suffix _0 is for root storage and the suffix _1 is for add-on storage, if it exists.
  • For a description of the values in the Type column, see the description of the metadata file in Monitoring service for plug-ins.
  • For details about the data that is collected by the UNIX agent, see the agent documentation.
  • The "Reference for auto scaling" column lists the strings that the auto scaling feature parses and uses to call the Monitoring API to get the corresponding metric value. The mount point values are not used by auto scaling, so a string for this metric is not listed the column.
