Addressing Time Series Requirements

Provide Security Performance Data to TSF

The Time Series Facility (TSF) displays security performance data in CA Chorus. Before you can view this data using TSF, statistics gathering in CA ACF2 or CA Top Secret must be started. Statistics gathering is the process of collecting system statistics and sending data to TSF for a specific time frame, which is measured in seconds.

Note: For more information about activating real-time statistics gathering in CA ACF2, see the CA ACF2 Administration Guide. For more information about activating real-time statistics gathering in CA Top Secret, see the CA Top Secret Control Options Guide.

The following diagram shows a real-time statistical gathering (STATG) configuration for a single enterprise:

This diagram shows a sample Time Series Facility configuration whereby three LPARs with three separate External Security Managers feed data to one Time Series Facility repository, which then is sent to JBoss.

Your external security manager uses the following process to provide real-time statistical data to TSF:

Checks to see whether real-time statistics are being gathered. If yes, data is passed to the TSF relay on remote systems and directly to TSF on the local system.
Data is saved in the TSF repository.

Note the following:

If you are sending data from CA ACF2 or CA Top Secret on a different LPAR than TSF, connect to TSF from the remote LPAR through the TSF Relay. For more information about the TSF relay, see the CA Chorus Installation Guide.
The Real-Time STATG is a sub-task of the external security manager, not a stand-alone STC.

For more information about TSF, see the CA Chorus Installation Guide.

For CA ACF2

To view CA ACF2 metrics in CA Chorus, the STATG bit in the GSO record must be turned on and statistics must be enabled with the Start command. You must wait for the time interval setting before data displays in the metrics panel. Metrics display only when actions are occurring.

Note: The Time Series Facility must be active in order for records to appear in the metrics panel.

Follow these steps:

Specify the following options in the CA ACF2 CHORUS GSO record on each LPAR from which you want to send data to TSF:

STATG

Specifies to start statistics gathering in CA ACF2 for TSF.

Default: NOSTATG

STATGINT(15|nn)

Specifies the time interval in seconds to capture statistical data that is routed to TSF.

Valid values: 15, 30, 60, 300, 900, 1800, or 3600 seconds

Default: 15

Recommended setting: 30

Issue the following commands:

ACF

SET CONTROL(GSO)
  CONTROL
INSERT CHORUS STATG STATGINT(30)

Issue the following commands to activate:
```
F ACF2,REFRESH(CHORUS)
```
Note: You can set additional options to identify the types of statistics you want to gather, define where statistics are written, and so on. For more information about these options, see the CA ACF2 Administration Guide. If CA ACF2 is restarted, statistical information is reset. If the STATG gathering task is deactivated using the STOP command, statistical information is not captured for TSF.

For CA Top Secret

To view CA Top Secret metrics in CA Chorus, the CHORUSSTATG(ON) control option must be set. You must wait for the time interval setting before data displays in the metrics panel. Metrics display only when actions are occurring.

Follow these steps:

Specify the following control options in CA Top Secret on each LPAR from which you want to send data to TSF:

CHORUSSTATG(ON)

Specifies to start statistics gathering in CA Top Secret for TSF.

Default: OFF

Important! Include CHORUSSTATG(ON) in the CA Top Secret parameter file so that it is available at CA Top Secret startup. Otherwise, statistical data gathering (STATG) in CA Chorus needs to be started manually.

CHORUSSTATI(nnnn)

Specifies the time interval in seconds to capture statistical data that is routed to TSF.

Valid values: 15, 30, 60, 300, 900, 1800, or 3600.

Default: 15

Recommended setting: 30

Note: You can set additional options to identify the types of statistics you want to gather, and so on. For more information about these options, see the CA Top Secret Control Options Guide.
Issue the following commands to activate:
```
TSS MODIFY(CHORUSSTATG(ON))
TSS MODIFY(CHORUSSTATI(30))
```
Security performance data is provided to TSF.
