All installed components include a set of default log flags for standard categories of messages. For example, all HMI/SCADA components can produce error, warning, and informational messages. These standard message categories have associated default log flags.
The following table lists default log flags for the standard message categories.
|
Default Log Flag |
Description |
|---|---|
|
Error |
The Error log flag determines if error messages are logged. By default, the Error log flag is active for all HMI/SCADA components. |
|
Warning |
The Warning log flag determines if warning messages are logged. A warning message indicates that an unexpected event occurred, but the component was able to recover. By default, the Warning log flag is active for all HMI/SCADA components. |
|
Info |
The Info log flag determines if informational messages are logged. An informational message describes the outcome of normal program events. By default, the Info log flag is active for all installed components. |
|
Trace |
The Trace log flag determines if trace messages are logged. Trace messages describe internal object states, variable values, and other low level data from the component. |
|
Scan On Demand |
The Scan On Demand log flag determines whether scan on demand-related MxConnection calls, reference counts, and suspend counts are logged. Also, the Scan On Demand log flag determines whether the routing of scan on demand messages to on-engine and off-engine objects are logged. |
|
SOD_BRO |
The SOD_BRO log flag determines whether tracing is enabled between the Lmx and the BRO. |
|
SOD_BROProxy |
The SOD_BROProxy log flag enables tracing when an interface is used to route a scan on demand message between a primitive and another primitive within the current object. |
|
SOD_PrimProxy |
The SOD_PrimProxy log flag determines whether tracing is enabled for the scan on demand interface between the BRO or a BRO proxy and a primitive proxy. |
|
Start-Stop |
The Start-Stop log flag determines if messages are logged that show when a component is started or stopped. |
|
Entry-Exit |
The Entry-Exit log flag determines if messages are logged that show when a program function was invoked. |
|
ThreadStart-Stop |
The ThreadStart-Stop log flag determines if messages are logged that indicate a program thread has started or stopped. |
|
SQL |
The SQL log flag determines if SQL messages are logged. Typically, SQL messages show SQL query strings issued by the component. |
|
Connection |
The Connection log flag determines if communication messages are logged. Communication messages describe the status of network connections between installed components. |
|
Ctor-Dtor |
The Ctor-Dtor log flag determines if constructor/destructor messages are logged. These messages describe the status of objects as they are created and deleted from memory. |
|
RefCount |
The RefCount log flag determines if reference count messages are logged. Reference messages show the counts from objects that manage their life span by counting their clients. |
