Scripting example in Jitterbit App Builder - Logging

Logging leverages Microsoft's Logging API. Logging helps debugging and maintaining a plugin, giving insight on current values, expected and unexpected behaviors. The example in this article demonstrates how to log messages.

Log severity

A message will only be logged if the Severity level is equal to or higher than the value configured on Minimum Severity under App Server Log Configuration for each log target configuration (Memory, Database, and Disk).

Severity levels

Microsoft Severity App Builder Severity Description
Off Off Configuration status where target log won't write any message, not intended for usage when logging.
Trace Trace Detailed message of minute steps, this status should be avoided in production enviroments.
Debug Debug Used during development to investigate state and behavior.
Information Info Used to track expected behavior, for example successfully processing a file.
Warning Warn Used when a behavior or state is not detrimental yet, but should be noted, for example disk running out of space.
Error Error Used when the current process has to stop due to a failure, for example unexpected data value from a file.
Critical Fatal Used when a failure requires immediate attention.

var logger = Services.GetRequiredService<ILogger>();

logger.LogWarning("My warning message");

Scope

Scoping is supported and allows additional information to be appended to the log record.

using Microsoft.Extensions.Logging;
using System.Collections.Generic;

var logger = Services.GetRequiredService<ILogger>();

logger.LogError("My unscoped error message");

// Appends "MyScope" to the log source
using (logger.BeginScope("MyScope")) {

    logger.LogWarning("My scoped warning");

    // Tags log records with the extra identifing properties.
    using (logger.BeginScope(new Dictionary<string, object>{
        ["CustomerId"] = 123,
        ["OrderId"] = 12
    })) {

        logger.LogWarning("My warning with extra data");

    }
}

Note

Any property added by the scope will be secured, meaning that to be recorded and displayed Log secure data has to be ON.
