Loggers - Transaction Groups

This article covers loggers related to Transaction Groups that were introduced in Ignition version 7.8.X.

Loggers in this article:

• SQL Bridge.GatewayHook

• SQL Bridge.{ProjectName}.{TransactionGroupName}

• SQL_Bridge-{ProjectName}

SQL Bridge.GatewayHook

• Monitors updates made to the project hosting Transaction Groups.
  • DEBUG log reporting a successful update made to a specific project containing Transaction Groups. Will provide the name of the project that contains translation groups:
    

    Gateway project 'Test' updated.

SQL Bridge.{ProjectName}.{TransactionGroupName}

• A logger monitoring enabled transaction groups and transaction groups dependent on triggers for execution. {ProjectName}.{TransactionGroupName} can be denoted as the name of the specific host project and transaction group defined within.
  • DEBUG log monitoring the start of an enabled Transaction Group:
    

    Starting group evaluation. Executing pre-trigger evaluation. Trigger is active. Executing post-trigger evaluation. Group evaluation completed.

• • DEBUG log stating both a detected trigger from a Transaction Group as well as a successful Store and Forward transaction to a data source. (Note: if the Transaction Group does not use triggers, the first line will be omitted in each execution):
    

    Trigger evaluated. Value: [93, Good, Tue Sep 14 12:10:41 PDT 2021], Active evaluation: true, Return value: true, First exec cancellation: false Historical forward transaction completed successfully.

• • TRACE log that will mention any detected expression items in the Transaction Group when initialized. {ExpressionItemName} can be denoted as the name of the expression item defined in the Transaction Group. This log is not an indication of any error:
    

    [[__GROUP__]{ExpressionItemName}] Child interaction listener fired, but scan class does not support async execution, or tag is already executing off of interaction update.

• • TRACE log that typically comes before the DEBUG logs stating the evaluation of triggers:
    

    Trigger received subscription update: [93, Good, Tue Sep 14 12:10:41 PDT 2021]

SQL_Bridge-{ProjectName}

• Monitors all defined Transaction Groups and the current values of all items for each group. {ProjectName} can be denoted as the name of the specific host project.
  • DEBUG log monitoring a transaction group that was started successfully. Will list all successfully loaded Transaction Groups that exist in the project:
    

    Project 'Test' loaded: 9 resources, 0 deleted Registering live value monitor. [B2BAA81BE72CAF014C80E2A42CCAB71C,18,null] setStatsMonitoredGroups:[[18]] Session:[B2BAA81BE72CAF014C80E2A42CCAB71C] Loaded group '/StandardGroupTest' for resource id '18'

• • DEBUG log monitoring the current values of a specific Transaction Group that is running. Expect this to update based on defined trigger evaluations or the poll rate of the Transaction Group:
    

    Found 4 values for 'StandardGroupTest' since last time of [Wed Dec 31 16:00:00 PST 1969]. Extended: [null] Session: [B2BAA81BE72CAF014C80E2A42CCAB71C] Value for 0: false, Tue Sep 14 12:10:26 PDT 2021 Value for 1: true, Tue Sep 14 12:10:39 PDT 2021 Value for 2: 93, Tue Sep 14 12:10:41 PDT 2021 Value for 3: 93, Tue Sep 14 12:10:41 PDT 2021
