13.1 Data Collection Overview

You can collect data in several different ways on both OpenVMS and UNIX platforms. On OpenVMS platforms you can also collected PATHWORKS data.

See Also OpenVMS Data Collection Overview UNIX Data Collection Overview PATHWORKS Data Collection Overview

13.1.1 OpenVMS Data Collection Overview

PerfCap Capacity Planner for OpenVMS uses data collected in several ways:

13.1.2 UNIX Data Collection Overview

PerfCap Capacity Planner for UNIX uses data collected in several mutually exclusive ways:

You cannot use data from both FullSail and the accounting/snapshot files.

Accounting/snapshot data collection is initiated through the Data Collector window of the PerfCap Capacity Planner.

See Also UNIX Data Collection Files

13.1.2.1 UNIX Data Collection Files

The system accounting data is collected in the normal system accounting data file. This data is written to a log file whose name you specified in the Data Collector window. The file type is .acct.

Additional data is collected by Capacity Planner snapshot utilities. This data is written to a log file whose name you specified in the Data Collector window. The file type is .snap.

A log file containing error and informational messages is also created. This information is written to a log file whose name you specified in the Data Collector window. The file type is .log. Data from system accounting and the snapshot utilities is merged by the Data Integrator.

13.1.3 PATHWORKS Data Collection Overview

The PATHWORKS software Version 5.0c includes a monitor that captures data for its PC clients. The PATHWORKS monitor is activated when you activate the Event Monitor. The PATHWORKS monitor stops automatically when you stop the Event Monitor.

See Also PATHWORKS Data Collection Files

13.1.3.1 PATHWORKS Data Collection Files

The PATHWORKS monitor writes its data on the server node where the PATHWORKS server process runs. For capacity planning purposes, data is written to the following files in the directory PWRK$PERFDATA:

  • PWRK$MON_CLIENT_nodename.DAT

  • PWRK$MON_DATA_CACHE_nodename.DAT

  • PWRK$MON_WORKLOAD_nodename.DAT

  • PWRK$MON_RESPONSE_nodename.DAT

  • PWRK$MON_QLENGTH_nodename.DAT
  • In these file names, nodename is the name of the server node.

    13.2 OpenVMS Data Collector

    The data collector accessed through the OpenVMS Data Collector window is the Event Monitor. The Event Monitor collects event data. It also activates the PATHWORKS monitor.

    You can specify common attributes, such as Start Time, End Time, Directory, and Batch Suffix and Qualifiers that will apply to all nodes for data collection.

    You can also select individual nodes for data collection and override the common attributes on an individual node basis.

    See Also Data Collection Common Attributes Panel Individual Nodes Attributes Panel

    13.2.1 Data Collection Common Attributes Panel

    Use the Data Collection Common Attributes panel to assign common attributes for data collection.

    See Also Performing Tasks in the Data Collector Window

    13.2.2 Individual Nodes Attributes Panel

    The Individual Node Attributes panel displays icons representing the nodes where the Event Monitor Data Collector is installed for data collection.

    To add or remove nodes for data collection, choose Select Nodes in the Options menu or click on the SELECT button. The Select Nodes dialog box is displayed.

    To set individual collection times and options for individual nodes, click on an icon to display the Data Collection Parameters dialog box.

    See Also Performing Tasks in the Data Collector Window

    13.3 UNIX Data Collector

    The data collector accessed through the Data Collector window is the Accounting/Snapshot data collector.

    You can specify attributes, such as Start Time, End Time, Directory, and Log File name that will apply to the system for data collection.

    13.4 Performing Tasks in the Data Collector Window

    The tasks that you can perform in the Data Collector Window are:

    See Also Data Collector Window

    13.4.1 Specifying Times for Data Collection

    To specify the period of data collection for the node or nodes on which you are collecting data:

    1. Press and hold MB1 first on the date field, then on the hour field, and then on the minute field next to the Start Time label.

      All the date, hour, and minute settings are displayed.

    2. Release on the date, hour, and minute that you want.

      The start time for data collection is displayed.

    3. Follow the previous steps to complete the fields next to the End Time label.

      The period for data collection on the node or nodes is displayed.

    See Also Setting Parameters for Individual OpenVMS Nodes

    13.4.2 Specifying VMS Options

    To specify the OpenVMS options for data collection:

    1. Enter the location for storing the data files in the Directory field.

    2. Batch Suffix (all nodes) or Batch Queue (individual node): Enter the suffix for the name of the batch queue on which you want to submit data collection in the Batch Suffix or Batch Queue field. The field shows the default suffix or queue name for the batch queue specified at installation time. The full batch queue name contains the name of the node followed by the suffix, for example, APOLLO$PSDC_BATCH.

    3. Enter batch qualifiers. See the DCL Help for the SUBMIT command to get additional information.

    4. Event Buffers (individual node): Use the slider to set the number of event buffers. You can specify from five to 50 event buffers in which to collect data. The default value is 10 unless you set the logical PSDC$EVENT_BUFFERS to another value for all nodes. If you are collecting large amounts of data for a node, you may wish to set a larger number of event buffers.

    13.4.3 Selecting VMS Nodes

    Data collection for all nodes in the VMScluster system is the default. However, you can select individual nodes that you want to monitor.

    To add nodes to or remove nodes from data collection:

    1. Click on the Select push button.

      or

      Choose Select Nodes from the Options menu.

      The Select Nodes dialog box is displayed.

    2. Follow the steps for completing the dialog box.

    13.4.4 Setting Parameters for Individual OpenVMS Nodes

    To set parameters for individual OpenVMS nodes, for example, start and end times for nodes that are different from the common data collection period:

    1. Click on the icon in the Individual Node Attributes panel.

      The Data Collection Parameters dialog box is displayed.

    2. Complete the fields in the dialog box.

    13.4.5 Specifying UNIX options

    To specify the UNIX options for data collection:

    1. Enter the location for storing the data files in the Directory field.

    2. Enter the name of the log file in the Log File field. The data collector creates files name.log, name.acct, and name.snap.

    13.4.6 Starting the Data Collector

    To start the Data Collector on all nodes (OpenVMS) or a node (UNIX):

      % snapshot.sh OFF

    2. Determine the PID of the snapshot process (you can also use this command to see if data collection is running):

      % ps auxww | grep snapshot

    3. Kill the collection process:

      % kill pid#
