Status storage options

Connection Execution Diagnostics Storages

New diagnostic storages for connection execution can be created here. The values that are transmitted in a connection are saved in these diagnostic storages. The storad values are being displayed when you click on a point in the status chart of a connection.

Preconfigured Connection Execution Diagnostics Storages

Diagnostic Storages overview

Rollover 4GB (default)	Saves a maximum of 4GB of data. When the limit is reached old data is being overwritten
Max10Entries	Saves at most values from the last 10 executions per connection.
3 Days	Saves data for 3 days. Older data is being deleted.
Discard	No data is being saved. Discard is well suited if no storage of the transferred data is required. This can save memory space.

Overview of the diagnostic memory for connection execution

The diagnostic memories are listed in a clear table.

On the left-hand side of each row, there are buttons for editing, deleting and duplicating the diagnostic memories. The star button can be used to set a diagnostic memory as the default. You can find out how these memories can be used for connections here: settings-for-connections-and-templates.md.

Create a Connection Execution Diagnostics Storage

Creating a new Diagnostics Storage

The following properties can be configured for a Diagnostics Storage:

Name	The name for the diagnostics storage. It is used to identify the Diagnostics Storage when projecting. Note: The name cannot be changed later.
Type of limitation	Storage limited Ring-Buffer: The amount of data that is stored before data is overwritten can be specified here. Retention time: Here you can specify how long the data is stored before it is being deleted. Ring-Buffer per connection: Here you can specify the maximum number of transfers per connection for which data is being saved before data is overwritten.

After creation, the newly created storage is displayed in the overview.

Diagnostic Data Logging

Here you can conveniently see what the current escalation level is.

For more information see: Escalation levels

Diagnostic Data Loggin with current escalation level

The following options can be configured for Diagnostic Data Logging

Maximum database size	The maximum amount of data in GB that can be stored. Default value: 8 GB.
Size of ring buffer	The maximum number of entries in the ring buffer. Default value: 2000 entries.
Maximum amound of characters in the status	The maximum number of characters that are saved for a value in the status display. Default value: 1000 characters

Transfer execution diagnostics

Here you can configure which transfer execution diagnostic data should be recorded and how much of it should be stored.

The following data can be recorded:

Notifications	History of sent notifications. Default value: 512 MB.
Connection status	The status history of connections. e.g. "Ready" or "Plug-in Error". Default value: 265 MB.
Plug-in status	The status history of plug-ins. e.g. "Ready" or "Error". Default value: 265 MB.

Diagnosis of the runtime service

Here you can configure which runtime service diagnostic data should be recorded and how much of it should be stored.

The following data can be recorded:

Service Events	History of Service Events. Default value: 265 MB.
Service Status	Status history of the runtime service. Default value: 265 MB.
Service Health	Health of the runtime service. Default value: 265 MB.
Performance metrics	Data on the performance of the OPC Router. Default value: 265 MB.

If enough data is available, an estimated recording rate and recording time are being shown for the diagnostic data of the transmission execution and the runtime service. This can look like this, for example:

Data recording estimates

Approximately 3.46 MB of data is being recorded per hour. This means that the data can be stored for approximately 3 days before it is being overwritten.
