Understanding Concurrent Signon Information
In some situations, it is necessary to be able to track and monitor the number of users that sign on to the system concurrently. For example, if your site has implemented a cost-per-user access agreement, system administrators need a method to determine usage, and to ensure compliance with any service-level agreements. The Performance Monitor enables you to capture and store concurrent user information and display a graphical view of the number of users signed on to your system at a given time. The concurrent signon information is extracted from existing Performance Monitor user signon information, summarized, and stored separately for concurrent signon monitoring.
Maintaining Chart Data
Access the Maintain Chart Data page (PeopleTools, Performance Monitor, History Concurrent Signon Chart, Maintain Chart Data).
The Maintain Chart Data enables you to set the criteria by which you purge and extract the concurrent signon user data. Once your criteria has been set, click Run to launch the PSPMCSOSUM Application Engine program, which extracts summary information for PMU 108 (user session ended) and PMU 109 (user session began) from Performance Monitor PMU tables.
Note: When the PSPMCSOSUM Application Engine program runs, it does not manipulate or alter existing data for PMU 108 and PMU 109. It extracts the previously stored PMU 108 and PMU 109 data required by concurrent signon monitoring and inserts the data into tables used by concurrent signon monitoring. When you purge concurrent signon information, you do not delete stored PMU data—only the summary data stored for concurrent signon monitoring is purged.

This example illustrates the fields and controls on the Maintain Chart Data page. You can find definitions for the fields and controls later on this page.
- Run Control ID
Because this page should only have limited access, the run control is not saved by user ID. A universal run control, Chart_Data_Process, exists for the PSPMCSOSUM Application Engine program.
- Chart Data Exists Up To
Displays how current the signon data is. This the last time the PSPMCSOSUM Application Engine program ran.
- Oldest Date
Displays the oldest date of stored signon summary data.
- Total Instances
Displays the number of rows of extracted PMU summary information stored in the concurrent signon tables.
- Purge Instances Older Than
To reduce the number of rows of stored PMU summary information, specify the date of the older rows that are no longer needed.
- Chart Begin Date
Displays the date of the oldest rows being stored for the concurrent signon chart.
- Chart Instances
Shows the number of rows of signon data being stored for displaying the concurrent signon chart.
- Purge Instances Older Than
To reduce the number of rows of chart data, specify the date of the older rows that are no longer needed.
- Instances To Purge
After specifying the chart data purge date, Instances to Purge displays the number of rows that will be deleted, showing the space you will reclaim.
- Bypass Chart Data Extract
Select if you only need to run the purge functions of the PSPMCSOSUM Application Engine program. In this case, only the specified information will be purged, and no new information will be added to the chart data.
- Bring Chart Up To Date
(Default) Extracts all concurrent signon information to update the chart data.
- Rebuild Chart Data Starting
Select to build the chart using data starting after the date you specify.
- Exempt OPRID's
To make specific user IDs exempt from appearing in chart data, add those IDs to this grid. For example, exempt IDs might include those used by administrators or consultants, not actually part of the user base or the service contract.
- Exempt IP Addresses
To make logins from specific workstations exempt from appearing in chart data, add either the IP address or the workstation name to this grid.
Viewing The Concurrent Signon Chart
Access the Concurrent Signon Chart page (PeopleTools, Performance Monitor, History Concurrent Signon Chart, Maintain Chart Data).
Use this page to filter and view the concurrent signon chart.

This example illustrates the fields and controls on the Concurrent Signon Chart page. You can find definitions for the fields and controls later on this page.
- Minimum Concurrent Users
Specify the minimum amount of concurrent users to track. Any record of current usage below this limit will not be included in the chart content.
- Show Only Duplicate OPRID's
Disables the Minimum Concurrent Users field and overrides its setting to 2. The chart content will be refreshed with only those instances where the same user ID was signed on to the system more than once simultaneously.
- Maximum Instances to Display
Use this setting to control how much information to display on the chart at a time. When viewing a chart with 100 instances (rows of data), details can become obscured, and the drill down capability becomes less effective. The chart can display a maximum of 999 bars.
- Refresh To End Date
Specify a particular date to position the chart so the very last data point for that day will be the last bar of the graph. This applies when the total number of rows in the chart data exceeds the Maximum Instances to Display value.
Click to refresh the chart based on the most recent filter criteria.
- Chart Filter Summary
Shows the information of the enter data set that can be displayed in the chart.
- Chart Scroll Controls
Enables you to scroll through the data and display multiple charts if not all the data is displayed at once. The scroll buttons for First, Prev, Refresh, Next and Last enable you to update the display. The First button refreshes the Chart so that the very first data point available will be shown as the first bar of the graph (or will position to the First/Last Scroll Date if specified). When the Prev or Next Button is clicked the graph moves to the prior/next set of data based on the Maximum Instances to Display setting.
Each instance (bar) in the chart displays hover text that describes the data the bar represents. You can drill down into each bar by clicking on it to display information similar to the following:

This example illustrates the fields and controls on the Concurrent Signon Drill-Down grid.
Note: In cases where a "switch user" occurred, the original user will be signed off at the same time the new user will be signed on. You can track and confirm this by drilling down into concurrent signon instances.
