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.

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. 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 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.
