Overview
This Historian module relies on other modules to store Tags' data. Therefore, the Historian Monitor provides exclusive information regarding the Historian system that manages the process of storing Tags' information. Therefore, the Historian Monitor will not provide information regarding the databases operation status.
As a result, many potential issues regarding data storage are out of the module's scope. Problems are usually related to external database repository, which requires specific tools to diagnose the problem. Despite being out of the Historian module scope, you can use the Diagnostic Tool such Module Information and Trace Window to acquire additional information regarding the Historian module operation.

Historian module
The Historian Monitor menu provides a way to monitor real-time information related to the Historian module operation. As the Historian Monitor has a monitoring-only function, you will not be able to edit or interact with Historian Tags, Historian Tables, or Archive Locations
The information available you you access the Historian Monitor is described in the table below.
Monitor information | Description |
|---|---|
ID | Historian Table unique identifier. |
Name Space | Specifies the namespace the item belongs to. |
Name | Historian Table's name |
Rows Count | The total number of row's data stored in the Historian Table. |
Success Count | The total number of times the system successfully store data into the database. [NOT SURE ABOUT THIS ONE] |
Error Count | Records the number of times the system failed to save data into the database. [NOT SURE ABOUT THIS ONE] |
Last Stored Time Stamp | Marks the timestamp of the last entry stored. |
Last Stored Error Message | Logs the last error message encountered. |
Access to the Historian Monitor
To have access to the Historian Monitor information, your solution must be running. Use the Runtime to start the solution.
Local Diagnostic Tools
As the Historian Monitor is not capable of providing additional information regarding the connected databases, you can use the Diagnostics toll for it. You will use the Module Information and the Trace Window to acquire additional information. To access these Diagnostic toll, access Runtime → Runtime Diagnostics.
Access to Module Information and Trace Window
You can only access these toll while your solution is running. Use the Runtime to start the solution.
Module Information
The diagnostic tool from the Information module updates in real-time information about the execution of the several module. To verify the Historian information, access the Module Information (info icon) and select the Historian option in the tree. By doing this, you can monitor the state of connected databases. The following table describe each available information when you select the Historian.
| Property | Description |
|---|---|
| Tables | The total number of Historian Tables. |
| Items | NOT SURE ABOUT THIS ONE |
| OpenStatusMessage | NOT SURE ABOUT THIS ONE |
| IsDeleting | NOT SURE ABOUT THIS ONE |
| StoreAndForward.IsEnabled | Specify if the system is using the Store and Forward feature. |
| UseStoreAndForwardDatabaseAlways | NOT SURE ABOUT THIS ONE |
| HasPairRedudantStoreAndForwardPending | Indicates if a Forward process to update the database is waiting due to connection issues. |
| Redundancy.LastSyncMessage | The last message received after synchronizing data with the database. |
| Redundancy.LastSyncTimestamp | Specify when the last synchronization happened. |
| Redundancy.LastSyncErrorMessage | Inform the last error message received when the synchronization failled. |
| Redundancy.LastSyncErrorTimestamp | Specify when the last failled synchronization happened. |
| StoreAndForward.IsFixingDatabase | Inform if the system is currently fixing the database data after facing issues synchronizing data. |
| StoreAndForward.FixDatabaseMessage | Message describing the origin problem when synchronization failed. |
| StoreAndForward.FixDatabasePercent | The total percentage already fixed. |
| StoreAndForward.FixDatabaseElapsedTime | The amount of time spent since the Store and Forward has started. |
If you select one specific Historian Table in the tree under Historian, additional information, described in the following table, will be available:
Property | Description |
|---|---|
| Table Name | The Historian Table's name. |
| Number of History Items | NOT SURE ABOUT THIS ONE |
| Number of Rows | The total number of row's data stored in the Historian Table. |
| Initialization Message | Message provided when stating the Historian. |
| Target | NOT SURE ABOUT THIS ONE |
| Disable | Inform if the Historan Table was disabled by the user before or while running the solution. You can control this option by accessing Runtime → Runtime Diagnostics. |
| Time Deadband | The dead band time defined configured for the Historian Table. |
| Life Time | The duration in days for retaining records on the Archive Location. The system automatically deletes data older than the specified value. |
| Save On Change | Inform if the Historian Table is using the Save On Change configuration to store new data. If true, whenever Tag's value change triggers an event to store the new data. |
| Save Quality | Inform if the Historian Table is using the Save Quality feature. For more information related to the Save Quality, access Historian Tables. |
| Normalized | Informe if the Historian Table is using the Normalize table schema for SQL databases. For more information on SQL database schemes, refer to the Archiving Process. |
| Deleting | NOT SURE ABOUT THIS ONE |
| Last Stored Time Stamp | The date and time of the last data stored into the database. |
| Last Stored Error Message | Message informing the problem related to the last problem preventing data to be stored. |
| Last Deleted Time Stamp | The date and time of the last time data was removed from the database. |
| Last Deleted Error Message | Message informing the problem related to the last problem preventing data to be removed from the database. |
| Last Samples Saved | NOT SURE ABOUT THIS ONE |
| Last Step During Saving | NOT SURE ABOUT THIS ONE |
| Error Count | Total number of errors related to the Historian Table operation. |
| Success Count | Total number of sucessfull data storage actions. |
| StoreAndForward.IsActive | Inform if the Historian Table is using the Store And Forward feature. NOT SURE ABOUT THIS ONE |
| StoreAndForward.NumberOfRows | NOT SURE ABOUT THIS ONE |
| StoreAndForward.LastStartedTimeStamp | Inform the last time the Store And Forward process was started to synchonize data with the database. |
| StoreAndForward.LastSyncTimeStamp | Inform the last time database data was synchonized. |
Historian TraceWindow
The TraceWindow diagnostic tool provides real-time logging of events connected with the Historian Module execution.
Four level of message can be enabled.
Module Information - Historian properties | |
|---|---|
Diagnostic Level | Types of messages included |
Info | Examples of events captured by this level: Info > PropertyWatch > User logged. Info > Module Information > User logged. Info > RichClient > admin > User logged. Info > Device > modbus > TRunModule.exe for channel modbus is stopped. Info > TModules.OPCServer > User logged. |
Warning | Review the application logs for any warnings. |
Error | Review the application logs for any error messages. |
Debug | Use debugging tools to inspect the state of the application at runtime |
