DC 5.5 Core Service configuration

This page documents the available options for the services the DAM Center has in Dotnet Core. The services are in the “DigizuiteCore” and “AutomationWorkflows” folders.

Logging

All settings are reloaded on-the-fly when the appsettings.json file is changed. I.e there is no need to restart the processes. You need, however, to have the entire path to the log file (sans the log file) pre-created upon load. This typically is only an issue for when you change the log path.

The following keys are available in the “Logging” section of the appsettings.json.

Some of these settings might not be visible by default, regardless of this, they may all be used.

Description

LogLevel

The amount of logging to be included. Valid values are:

  1. None ← Least

  2. Critical

  3. Error

  4. Warning

  5. Information

  6. Debug

  7. Trace ← Most

With each log level has more info than the former (including the former).

Overrides

A dictionary that can be used to change the log level of certain namespaces. Usually not something you need to change.

For example - the following:

"Overrides": { "Microsoft.EntityFrameworkCore": "Warning" },

reduces the LogLevel of Entity Framework to Warning, rather than the normal log level set for the rest of the service. Multiple keys can be set at the same time.

LogDirectory

The path to the directory where the log files

DaysToKeepLogFiles

How many days to keep log files before deleting them

MaxLogFileCount

How many files to keep per service at the most.

Note

There may be times when one or more applications fail to fully start. This is usually due to an issue with the environment. In case of this happening, it may be useful to access the failing services' Web.Config files, and enable stdout logging. Please be very cautious when enabling this, as it doesn’t clean up after itself. Once the service is up and running anew, there’s a real threat of it filling the disk entirely if not disabled again.

Log server configuration

The log server has the following configuration options:

Option name

Description

Option name

Description

LogPath

The location of the log files on disk (Can be either a relative or absolute path)

LogFileSizeCutoff

The size in MB that determines (roughly) how big each log file should be allowed to become

LogStorageType

Determines what kind of storage to use. Currently, only “Local” is supported.

CleanupStrategy

What cleanup strategy to use. Either Duration or Count. Duration will keep all log files in a certain period, no matter the count. Count will only ever keep a certain amount of log files, no matter the period.

OldLogFileCount

Determines how many old log files can be at the same time, if using the Count strategy

KeepDuration

How long the log files will be kept, if using the Duration strategy. Use the C# TimeSpan format.

All these settings can be changed on-the-fly, without requiring a restart of the LogServer process.

Integration Service

The Integration Service debounces messages before sending updates to subscribing integration endpoints. The debounce interval can be configured by adding a “Debouncing” section to the appsettings.json file for the Integration Service. This section has the following configuration options:

Option name

Interval

The debouncing interval to use when debouncing messages before sending them to subscribing integration endpoints.

Timespan

Internal Debouncing

A lot of services are debouncing messages using the Debouncing Service. The Debouncing Service can be configured by adding a “InternalDebouncing” section to the appsettings.json file for the Debouncing Service. This section has the following configuration options:

Option name

Default value

SleepInterval

The Debouncing Service periodically checks if it has any messages that have been debounced and should be sent back to the origin. This parameter configures the sleep time between each check.

Timespan

00:00:00.200” (200 milliseconds)

ReturnLimit

The maximum number of messages returned at each of the periodical checks.

Integer

10000

Note that all parameters above are optional. It is possible to configure one parameter without configuring the other.

Workflows

The Business Workflow Service can be configured by adding a “BusinessWorkflow” section to the appsettings.json file for the Business Workflow Service. This section has the following configuration options:

MigrationInstanceLimit

When an existing workflow is updated, the existing workflow instances for this workflow are migrated to the new version. This parameter sets the maximum number of instances to migrate at a time.

Note that all instances using the previous version of the workflow are always migrated. Thus, this parameter can primarily be used to tweak performance.

Integer
