Collection Services collection profiles

Descriptions of the Collection Services collection profiles. The collection profiles define what is collected.

  • Minimum - The Minimum collection profile includes the most essential categories. Note: This profile does not contain all the categories that are required by the tools in IBM® Performance Tools for i licensed program. The Minimum collection profile includes the following categories:
    • System bus: This category contains data on the operation of each system bus.
    • Memory pool: This category contains memory pool configuration data and memory pool operation data.
    • Hardware configuration: This category contains hardware resource information for the system. This category contains the same data that the Display Hardware Resources (DSPHDWRSC) command acquires. Only the first instance of this data is reported in the database if more than one instance is encountered.
    • System CPU: This category contains data on system CPU usage for each processor.
    • System-level data: This category contains general system data that is used on a system-wide basis.
    • Job (MI tasks and threads): This category contains information on every active task, job, and thread in the system. The data that is collected is provided by the machine interface (MI).
    • Job (operating system): This category contains information on every active job in the system. The data that is collected is provided by the operating system.
    • Disk storage: This category contains system storage unit data. It includes base storage unit information and operational data for disk drives.
  • Standard - The Standard collection profile includes the data categories that are typically needed by the tools in IBM Performance Tools for i licensed program. The data categories in the Standard profile include all the categories in the Minimum profile plus the following categories:
    • Memory pool tuning: This category contains pool tuning configuration data for each system memory pool.
    • Subsystem: This category contains data on active subsystems and subsystem pools. Only the first instance of this data is reported in the database if more than one instance is encountered.
    • SNADS: This category contains transaction boundary information specific to active SNADS jobs in the system.
    • Local response time: This category contains response time information for workstations that are connected to 5254 controllers. Response time data is reported for each workstation and is saved in a set of response time buckets.
    • APPN: This category contains data on the system's APPN support. The data contains both general information and data classified according to transaction type and work activity.
    • SNA: This category contains data on the system's SNA support. Controller, task, and session data are reported for each active T2 task.
    • TCP/IP (base): This category contains system-wide performance information for TCP/IP.
    • User-defined transaction data: This category contains data for application-defined transactions rather than IBM-defined transactions. You can create your own user-defined transactions.
    • IBM Domino® for i: This category is included in this profile when the IBM Domino for i licensed program is installed on the system.
    • IBM HTTP Server for i (powered by Apache): This category is included in this profile when the IBM HTTP Server for i licensed program is installed on the system.
    • External storage: This category contains non-standardized data for disk units that are externally attached to an IBM i partition.
    • System internal data: This category contains internal data for the system.
    • Removable storage: This category contains data about removable storage devices that are connected to the system, more specifically tape device data.
    • SQL: This category contains performance information for SQL, more specifically SQL Plan Cache data.
  • Standard plus protocol - The Standard plus protocol collection profile includes communications protocol data categories and the data categories that are typically needed by the tools in IBM Performance Tools for i licensed program. The data categories in the Standard plus protocol profile include all the categories in the Standard profile with the addition of the following categories:
    • Network server: This category contains information about network servers. For Integrated xSeries Servers, data is reported for CPU utilization. For virtual I/O adapters on hosting partitions (partitions that provide the physical resources), data is provided about the I/O activity that occurs within this partition due to the virtual device support that it is providing on behalf of guest partitions.
    • Communications (base): This category contains base protocol information for each communication line that is available for use (varied on).
    • Communications (station): This category contains station information for certain communication lines. Data is reported for each station that is available for use (varied on). Protocols supporting this data are Token Ring, Ethernet, DDI, Frame Relay, and X.25.
    • Communications (SAP): This category contains Service Access Point (SAP) information for certain communication lines. Data is reported for each configured SAP within lines available for use (varied on). Protocols supporting this data are Token Ring, Ethernet, DDI, and Frame Relay.
    • Data port services: This category contains performance data that is obtained from data port services. Data port services is Licensed Internal Code that supports the transfer of large volumes of data between a source system and one of any number of specified target systems in an IBM i cluster environment. Data port services is used by Licensed Internal Code clients, such as, remote independent auxiliary storage pool (ASP) mirroring.
    • TCP/IP interface: This category contains information for each active TCP/IP interface.
    • Start of changeRDMA: This category contains performance data about network redundancy groups and Remote Direct Memory Access (RDMA) links. End of change
  • Enhanced capacity planning - The data categories in the Enhanced capacity planning profile include all the categories in the Standard plus protocol profile with the addition of the PEX Data - Processor Efficiency data category. The PEX Data - Processor Efficiency data category contains the cycles per instruction for Performance Explorer (PEX) data. Data is collected to enhance capacity planning capabilities or for other purposes. Special considerations apply when you use this category:
    • A Performance Explorer definition, QPMIPEXPEI, is created. If the Performance Explorer definition exists, it is deleted and re-created.
    • This category requires Collection Services to start a Performance Explorer (PEX) collection (session-ID QPMINTPEXD). This collection can conflict with other Performance Explorer collections.
    • Do not end or start the QPMINTPEXD session manually because it affects the validity of the data collected.
    • When collection of this category stops, it also ends the Performance Explorer collection for session QPMINTPEXD.

    IBM no longer recommends using this profile.

  • Custom - This option allows for customization of not only the data categories that are collected, but also the specification of the interval. You can have different categories of data that is collected at different intervals.
