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

PerfCap Capacity Planner for OpenVMS uses data collected in several ways:
See the PerfCap Performance Data Collector and Utilities User's Guide for details about collecting OpenVMS .CPD data files.
The Event Monitor is activated through the Data Collector window of the PerfCap Capacity Planner.
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.

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.
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.

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:
In these file names, nodename is the name of the server node.
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.

Use the Data Collection Common Attributes panel to assign common attributes for data collection.
See Also Performing Tasks in the Data Collector Window
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.

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.

To specify the period of data collection for the node or nodes on which you are collecting data:
All the date, hour, and minute settings are displayed.
The start time for data collection is displayed.
The period for data collection on the node or nodes is displayed.

To specify the OpenVMS options for data collection:
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:
or
Choose Select Nodes from the Options menu.
The Select Nodes dialog box is displayed.
To set parameters for individual OpenVMS nodes, for example, start and end times for nodes that are different from the common data collection period:
The Data Collection Parameters dialog box is displayed.
To specify the UNIX options for data collection:
To start the Data Collector on all nodes (OpenVMS) or a node (UNIX):
In the Data Collector window:
or
To start the Data Collector on an individual OpenVMS node, click on the Start DC button in the Data Collection Parameters dialog box for that node.
An informational message displays the submitted command procedure in the Session Log window. An informational message is also displayed on the screen.
Normally, data collection will end at the End Time you specified when starting data collection.

To end data collection prematurely, take the following steps:
% snapshot.sh OFF
% ps auxww | grep snapshot
% kill pid#

Use the Batch Suffix field to enter another batch queue name suffix to run the batch command procedure for VMS data collection. The default is $PSDC_BATCH, which you specified at installation time. The full batch queue name contains the name of the node followed by the suffix, for example, APOLLO$PSDC_BATCH.
