Overview

The VFC to WFE Metadata Integrator must be configured to connect to both the VFC and WFE environments.

When the Integrator is installed, appsettings.json, a default configuration file is created in the Integrator installation folder (referenced as INSTALLDIR in the Installation Guide), where the Vfc.Integrator.Service.exe file is located. This file is read-only, and only serves as a reference for the default values supplied with the installation.

When the Integrator first runs, it creates its editable configuration file, appsettings.<environmentName>.json. The default value of environmentName is Production, otherwise, if configured, the value matches the environment variable DOTNET_ENVIRONMENT. Any references to appsettings.Production apply to this file.

The configuration of the Integrator must take place in the appsettings.Production.json file, and missing or incorrect values can cause the Integrator service to fail.

Not all parameters in the file must be modified. Always refer to the following modifiable columns, whether a specific parameter can be modified.

More configuration settings are stored in the PersistedSettings.json file, which must not be manually modified. When updating, repairing, or uninstalling an existing Integrator installation, the appsettings.Production and PersistedSettings files, the Logs folder and its contents remain, while all other files get removed.

You must restart the Integrator service after making changes to the appsettings.Production file.

Prerequisites

Before you begin the configuration, the following items must be completed:

  1. Ensure all steps in the Prerequisites and Deployment process sections of the VFC to WFE Metadata Overview are complete.
  2. Follow the Installation Guide to install the VFC to WFE Metadata Integrator. Verify the installation returned no errors.

Compulsory appsettings parameter configuration

There are values in the appsettings.Production file that must be configured to match your deployment. Some of these values include default values, some of which need to be overwritten with correct values or the Integrator cannot run. Some of the values are optional to edit or include.

Non-compulsory appsettings parameter configuration

There are values in the appsettings.Production file that are internal to the Integrator and have been configured for optimal operation. Most of these values should only be changed with caution.

HighAvailability

Parameters relating to the Integrator resilience.

Parameter

Description

Default value

Modifiable

LockTimeout

The VFC database lock timeout period of this Integrator instance. The timeout starts when the database does not receive a heartbeat signal from the Integrator. When the timeout period elapses, this Integrator loses ownership and other Integrators can claim it.

00:10:00

Modify with caution

Refer to Resilience to find out more about the usage of the VFC database lock.

Bootstrap

Parameters relating to the dependency verification of the Integrator.

Parameter

Description

Default value

Modifiable

DependencyRecheckIntervalSeconds

The timeout period after all failing dependency readiness checks are retried.

30

Modify with caution

The Integrator depends on several parameters and connections being accurately set up, and runs an internal dependency check service. The status of dependencies is saved, and if a dependency failed during the last check, new verification process runs after the DependencyRecheckIntervalSeconds period elapses.

Synchronisation

Parameters relating to the synchronization process carried out by the Integrator.

Parameter

Description

Default value

Modifiable

ResyncStartAtTimeOfDay

The time of day when the next attempt is made to synchronize user, group, recording expectation, and extension data. Ranging from 00:00:00 to 23:59:59 in the hh:mm:ss format. The time is in the time zone of the server on which the Integrator runs.

01:00:00

Yes, can be modified

PermanentErrorRetryDelay

The time delay to retry a synchronization attempt if a persistent error happens that needs human interaction (for example, a configuration problem). Ranging from 00:00:00 to 23:59:59 in the hh:mm:ss format.

00:01:00

Modify with caution

TransientErrorRetryDelay

The time delay to retry a synchronization attempt if a temporary error happens that does not need human interaction (for example, a network outage). Ranging from 00:00:00 to 23:59:59 in the hh:mm:ss format.

00:00:05

Modify with caution

Specify ResyncStartAtTimeOfDay based on your system and organizational usage trends. Choose a time in the day when the least network activity takes place to avoid affecting business-critical operations.

CallMarking

Parameters relating to the process of the Integrator marking call data to the WFE environment.

Parameter

Description

Default value

Modifiable

IntervalMs

The delay between batches of calls processed to be marked to WFE in milliseconds.

5000

Modify with caution

ReadBatchSize

The number of calls to be read from the VFC database and marked to be sent to WFE at a given time.

1000

Modify with caution

PostCallDelayInMinutes

The delay between a VFC call being completed and it being considered for call marking to WFE.

1

Modify with caution

VirtualRecorderSerialNo

The Serial Number of the WFE recorder object created to represent the VFC installation from which the Integrator is synchronizing recorded call metadata. The calls marked to WFE are associated with this virtual recorder. Must be unique to a VFC installation. Refer to the Configuration Guide for the format requirements of the parameter.

Empty

Yes, must be modified

WfeApiRootPath

The path address of the WFE Data Marking API.

/api/recording/marking/v1

No

InitialHistoryDays

The earliest point in time that the Integrator marks call data. It is configured as a number of days in the past to mark as the initial watermark for marking calls, and the Integrator does not check for calls before this point in time.

0

Yes, can be modified


Call marking is the process of reading in a call record from the VFC database, evaluating it against the Integrator configuration, and sending it to the WFE database. These parameters define how often calls get marked, and how many call records are processed at a time.

Changing the default values can have significant impact on system performance. Modify these parameters with caution.
  • The values of InternalMs and ReadBatchSize can be adjusted depending on call volumes.
  • The PostCallDelayInMinutes starts after the last update is made to the call record in the database. Any of the internal VFC services can update a record, therefore the parameter is specific to system configuration. The value can be adjusted depending on system and network connection speed. Setting the parameter to too large a value can result in calls taking excessively long to be synchronized for use by WFE applications. In cases of high call volumes, this can also cause large batches of data to be processed simultaneously, increasing network traffic. Too short a time value can result in calls being marked repeatedly as VFC internal services update the database record of the call, causing excess load on the system and the network.
  • The VirtualRecorderSerialNo must specify the Serial Number of the External Server created earlier in the VFC to WFE Metadata Integrator deployment process, and it must be unique to both a VFC and a WFE installation. It must be a 6-digit number in the format XXXYYY, where XXX is a 3-digit unique identifier for the VFC installation, and YYY is a 3-digit unique counter, incrementing for each Integrator.
  • InitialHistoryDays specifies a number of days before the current time, and the Integrator only marks calls that were made since that point in time. This parameter is only applied on the first run of the Integrator.

See Recorders and call metadata for more information about call marking.

RecordingExpectation

Parameters relating to the synchronization of extensions.

Parameter

Description

Default value

Modifiable

WfeApiExtensionsChunkSize

The number of VFC extensions to be sent to the WFE API at a given time.

1000

Modify with caution

VfcDbExtensionsBatchSize

The number of VFC extensions to be read from the VFC database at a given time.

1000

Modify with caution

ContactIdCaching

Parameters relating to the processing of contact objects during the call metadata synchronization process.

Parameter

Description

Default value

Modifiable

MaximumCachedEntries

The maximum number of contact objects to be stored in the cache. Default: 200000.

200000

Modify with caution

MaximumSupportedContactStartTimeDifference

Absolute expiration time of the contact cache entries relative to the current time, in the format hh:mm:ss, between 00:00:00 and 12:00:00. Also defines the maximum time difference allowed between the start times of the call sessions under the same contact.

12:00:00

Modify with caution

The unit of measurement for the MaximumCachedEntries parameter is number of contact objects. As the concept of contacts describes related call sessions in VFC, contact objects can be different sizes depending on the number and length of related calls, but this setting has no effect on overall system performance.

See Recorders and call metadata for more information about contacts.

Advanced - ResponseCaching

Parameters relating to the caching of HTTP responses from WFE APIs.

Parameter

Description

Default value

Modifiable

DefaultSoftCacheLifeTime

The time interval after which cached responses from WFE APIs are invalidated if the cache was not used. In the format dd.HH:mm:ss.SSS (where dd and SSS are optional values).

00:10:00

Modify with caution

HardCacheLifeTime

The time interval after which a cached response from a WFE API is always invalidated, no matter what the status of the API is. In the format dd.HH:mm:ss.SSS (where dd and SSS are optional values).

12:00:00

Modify with caution

MaxCacheSize

Maximum number of responses from WFE APIs to HTTP requests to be stored at any given time.

1000

Modify with caution

SoftCacheLifeTimes

The time interval after which a cached response from a specific WFE API is invalidated if the cache was not used. Overwrites the value set in DefaultSoftCacheLifeTime for the specified API. In the format dd.HH:mm:ss.SSS (where dd and SSS are optional values).

"/wfo/api/em/recorder/v2/datasources": "00:10:00"

Modify with caution

The Integrator caches responses from WFE APIs to some HTTP requests to minimize network communication and load on the APIs. To keep data relevant, cached responses are periodically invalidated, and new queries are sent to the APIs. Some cached responses are only invalidated if they are not queried by the Integrator in a set time period, while others are always invalidated after a time.

These parameters must only be modified with caution to avoid adverse impact on system performance.

Advanced - ArchivedLogsCleanup

Parameters relating to the archiving of log files.

Parameter

Description

Default value

Modifiable

ArchivedFolderName

The path and folder name to store the zipped archived logs. It is relative to the Serilog path parameter configured. If left empty or the parameter is omitted, the archived files are created in the Serilog log folder.

Archived

Yes, can be modified

CompressionLevel

The level of compression. The value is one of the following: NoCompression, Fastest, Optimal, SmallestSize. Default: SmallestSize.

SmallestSize

Modify with caution

KeptArchivesCount

The number of archived log files to keep. Setting to 0 means all archived log files are kept.

30

Modify with caution

  • The ArchivedFolderName parameter describes where archived log files are saved, relative to the Serilog Logs folder.
  • The CompressionLevel parameter sets the level of compression to apply to the archiving of a log. Setting the parameter to a low compression setting can impact system performance, so edit with caution.
  • The KeptArchivesCount parameter specifies how many archived log files can be kept. Specifying the value as 0 keeps all archived log files. Setting the parameter to too high a number can impact system performance, so edit with caution.
