35.40FHIR Performance Tracing

The FHIR Performance Tracing configuration category includes the following configurable options:

Capture Raw SQL or Equivalent
Trigger
Performance Tracing Enabled
Output to Response Headers
Output to System Log
Output to Transaction Log

35.40.1Property: Capture Raw SQL or Equivalent

Property Name	Capture Raw SQL or Equivalent
Property Key
Property Type	BOOLEAN
Description	If this is enabled, the raw SQL commands issued to the database will be captured. In the case of non-SQL storage modules (e.g. MongoDB) the raw queries will be captured instead. Note that this can have a measurable impact on performance so this should be enabled only to troubleshoot specific issues.
Applies to Modules	FHIR Storage (DSTU2 Relational) FHIR Storage (MongoDB) FHIR Storage (R3 Relational) FHIR Storage (R4 Relational)
Default Value	`true`
Example Property	`module.[MODULE_ID].config.performance_tracing.capture.raw_sql = true`

35.40.2Property: Trigger

Property Name	Trigger
Property Key
Property Type	ENUM
Values	`ALL_REQUESTS` `ON_DEMAND`
Description	Adjust this setting to determine which transactions are traced.
Applies to Modules	FHIR Storage (DSTU2 Relational) FHIR Storage (MongoDB) FHIR Storage (R3 Relational) FHIR Storage (R4 Relational)
Default Value	`ALL_REQUESTS`
Example Property	`module.[MODULE_ID].config.performance_tracing.capture.trigger = ALL_REQUESTS`

35.40.3Property: Performance Tracing Enabled

Property Name	Performance Tracing Enabled
Property Key
Property Type	BOOLEAN
Description	Enable this setting in order to enable detailed performance tracing. Note that this feature has an impact on performance itself, so it should be enabled with caution on production systems. The other settings in this category will have no effect if this is not enabled. See Performance Tracing for more information. If this setting is disabled, all other performance tracing settings will be ignored.
Applies to Modules	FHIR Storage (DSTU2 Relational) FHIR Storage (MongoDB) FHIR Storage (R3 Relational) FHIR Storage (R4 Relational)
Default Value	`false`
Example Property	`module.[MODULE_ID].config.performance_tracing.enabled = false`

35.40.4Property: Output to Response Headers

Property Name	Output to Response Headers
Property Key
Property Type	BOOLEAN
Description	Should performance tracing logs be appended to the HTTP response headers?
Applies to Modules	FHIR Storage (DSTU2 Relational) FHIR Storage (MongoDB) FHIR Storage (R3 Relational) FHIR Storage (R4 Relational)
Default Value	`true`
Example Property	`module.[MODULE_ID].config.performance_tracing.output.response_headers = true`

35.40.5Property: Output to System Log

Property Name	Output to System Log
Property Key
Property Type	BOOLEAN
Description	Should performance tracing logs be appended to the System Logs?
Applies to Modules	FHIR Storage (DSTU2 Relational) FHIR Storage (MongoDB) FHIR Storage (R3 Relational) FHIR Storage (R4 Relational)
Default Value	`false`
Example Property	`module.[MODULE_ID].config.performance_tracing.output.system_log = false`

35.40.6Property: Output to Transaction Log

Property Name	Output to Transaction Log
Property Key
Property Type	BOOLEAN
Description	Should performance tracing messages be appended to the Transaction Log?
Applies to Modules	FHIR Storage (DSTU2 Relational) FHIR Storage (MongoDB) FHIR Storage (R3 Relational) FHIR Storage (R4 Relational)
Default Value	`true`
Example Property	`module.[MODULE_ID].config.performance_tracing.output.transaction_log = true`
