Expert Settings

This section contains information about the expert settings UI and individual technical settings that can be used to adjust the behavior of the ABAP Agent.

Warning: It is not recommended to change the parameter values without sufficient technical knowledge about the affected area and what impact the change can have on the agent and the SAP system.

To access the Expert Settings UI, use t-code /DVD/APPD_PARAM. The following parameters are available:

Parameter Area Usage
ANALYTICS_STRING_SIZE Analytics Overrides maximum length of a string value that is propagated from CrystalBridge® Monitoring detail table fields to analytics schema columns.
Note: Setting this parameter to a high value may exceed the event service limits for string value length. So, we do not recommend you to set this parameter above 4000.
ANALYTICS_MESSAGE_SIZE C++ SDK / Transaction Analytics Size of the entire analytics request message in bytes.
ANALYTICS_SEGMENTS_PER_REQUEST C++ SDK / Transaction Analytics Maximum number of analytics segments that can be sent in a single analytics request.
ANALYTICS_SEGMENT_SIZE C++ SDK / Transaction Analytics Size of a single analytics segment in bytes.
ARFC_FREE_LIMIT ABAP Agent This tells the ABAP Agent how many aRFC resources it needs to keep free on every SAP application server. When ABAP Agent reaches this limit, it will end business transactions synchronously (in user session).
BTC_USER_ID ABAP Agent This parameter can be used to set a specific SAP user to be used in automatically scheduled ABAP Agent background jobs (For example, APPD_STAD_COL, APPD_HOUSEKEEP_COL). The selected SAP user needs to exist in the SAP client where AppDynamics integration will be activated using t-code /DVD/APPD_CUST. For all ABAP Agent background jobs to work correctly, the user needs to have the authorization role /DVD/APPD_ADMIN.
BT_DATABASE_EXITCALL HTTP SDK / Business Transactions Enables primary database exit call propagation with every business transaction. Exit calls will have the same run time and start time as business transaction. After you enable this option, restart HTTP SDK to take effect.
HOUSEKEEP_JOB_PERIOD ABAP Agent This tells the ABAP Agent how frequently it needs to start the housekeeping job. This job removes certain files and table data generated by the instrumentation process.
HTTP_SDK_CONT_IGNORE_CRL HTTP SDK / SSL Specifies whether to ignore the Certificate Revocation List (CRL) when SSL is used to connect from the HTTP SDK or C++ SDK to the Controller. This parameter is applicable only for Windows.
HTTP_SDK_CONT_SKIP_CERT_VAL HTTP SDK / SSL Specifies whether to skip certificate validation when SSL is used to connect from the HTTP SDK or C++ SDK to the Controller. This parameter is applicable only for Windows.
HTTP_SDK_EVT_LIMIT HTTP SDK / Events Overrides number of events that can be pushed to controller each minute when using HTTP SDK for event propagation. HTTP SDK (re)start is required after changing the parameter.
HTTP_SDK_NUM_THREADS Experimental This parameter can be used to increase the number of processing threads for the Linux version of HTTP SDK. Use at your own risk.
HTTP_SDK_METRIC_BATCH HTTP SDK / Metrics By default, this setting is enabled. It enables metrics (KPIs collected using CrystalBridge® Monitoring) to be reported in batches. As a result, it reduces the HTTP calls to HTTP SDK and decreases resource consumption. Earlier, the metrics were sent one by one in a sequence.
IOT_BEACONS_PER_REQUEST SAP GUI EUM Overrides number of beacons that can be transmitted to the IoT API in one HTTP request.
IOT_EVENTS_PER_BEACON SAP GUI EUM Overrides number of events that can be stored in a single beacon.
IOT_EVENTS_PER_REQUEST SAP GUI EUM Overrides maximum number of events that can be transmitted to the IoT API in one HTTP request regardless of number of beacons.
TRACE_SAT_GUI_MIN_WP_TIME Trace / GUI / SAT The threshold for proactive SAPGUI ABAP trace. When a work process is active for longer than the threshold value (at the time of APPD_STAD_COL job execution), tracing logic will pick the work process as one of the candidates for tracing.
TRACE_SAT_PARAL_SERVER_LIMIT Trace / SAT Maximum number of allowed ABAP SAT traces. This parameter controls number of ABAP Agent’s trace instances that can run concurrently on server level.
TRACE_SAT_GUI_REACTIVATE Trace / GUI / SAT Once SAT trace is activated for a specific t-code, the proactive tracing mechanism will wait this long before the t-code can be traced again.
TRACE_ST05_GUI_MIN_WP_TIME Trace / GUI / ST05 The threshold for proactive SAPGUI SQL trace. When a work process is active for longer than the threshold value (at the time of APPD_STAD_COL job execution), tracing logic will pick the work process as one of the candidates for tracing.
TRACE_ST05_GUI_REACTIVATE Trace / GUI / ST05 Once the ST05 trace is activated for a specific t-code, the proactive tracing mechanism will wait this long before the t-code can be traced again.
