Version 3.4.0-BETA.2

Migration notes:

  • If you were using Automatic naming before, you will need to update your module-info.java file Change requires applicationinsights.runtime.attach; to requires com.microsoft.applicationinsights.runtime.attach; and everything should work

Enhancements:

  • Automatic module name entry added to Runtime Attach library Jar to support Modular Java

Version 3.4.0-BETA

Migration notes:

  • Rate-limited sampling is the new default. If you have not configured a sampling percentage and are using the prior default behavior of 100%, you will get the new default which limits the total requests captured to (approximately) 5 requests per second. If you wish to continue with the previous behavior, you can explicitly specify a sampling percentage of 100, e.g. 
    {
  "sampling": {
    "percentage": 100
  }
}
  • Both percentage-based and rate-limited sampling now only apply to requests, and to telemetry that is captured in the context of a request If you do want to sample "standalone" telemetry (e.g. startup logs), you can use sampling overrides, e.g. 
    {
  "preview": {
    "sampling": {
      "overrides": [
        {
          "telemetryType": "dependency",
          "includingStandaloneTelemetry": true,
          "percentage": 10
        }
      ]
    }
  }
}

Enhancements:

  • Standard metrics for HTTP requests and HTTP dependencies are now pre-aggregated inside of the Java agent, and so they are no longer affected by sampling (#2439)
  • Rate-limited sampling has been introduced which can be used to tune ingestion costs (#2456), e.g. 
    {
  "sampling": {
    "limitPerSecond": 5
  }
}
    Note: the limitPerSecond can be a decimal value, including values less than 1
  • Exceptions are no longer captured directly on dependency records for these reasons:
    • in order to reduce ingestion cost
    • dependency exceptions which are uncaught, bubble up to the request-level where they are already captured
    • dependency exceptions which are caught, tend to be logged if they are important, where they are also already captured (#2423)
  • New versions of the applicationinsights-core and applicationinsights-web 2.x SDK artifacts have been released, with a reduced API surface area to makes it clear which APIs interop with the 3.x Java agent (#2418) These new versions are no-ops when run without the Java agent. To update your dependencies:
    2.x dependency Action Remarks
    applicationinsights-core Update the version to 3.4.0-BETA or later
    applicationinsights-web Update the version to 3.4.0-BETA or later, and remove the Application Insights web filter your web.xml file.
    applicationinsights-web-auto Replace with 3.4.0-BETA or later of applicationinsights-web
    applicationinsights-logging-log4j1_2 Remove the dependency and remove the Application Insights appender from your log4j configuration. This is no longer needed since Log4j 1.2 is auto-instrumented in the 3.x Javaagent.
    applicationinsights-logging-log4j2 Remove the dependency and remove the Application Insights appender from your log4j configuration. This is no longer needed since Log4j 2 is auto-instrumented in the 3.x Javaagent.
    applicationinsights-logging-log4j1_2 Remove the dependency and remove the Application Insights appender from your logback configuration. This is no longer needed since Logback is auto-instrumented in the 3.x Javaagent.
    applicationinsights-spring-boot-starter Replace with 3.4.0-BETA or later of applicationinsights-web The cloud role name will no longer default to spring.application.name, see the 3.x configuration docs for configuring the cloud role name.
  • ConnectionString overrides were introduced, and InstrumentationKey overrides were deprecated (#2471): 
    {
  "preview": {
    "connectionStringOverrides": [
      {
        "httpPathPrefix": "/myapp1",
        "connectionString": "InstrumentationKey=12345678-0000-0000-0000-0FEEDDADBEEF;IngestionEndpoint=...;..."
      },
      {
        "httpPathPrefix": "/myapp2",
        "connectionString": "InstrumentationKey=87654321-0000-0000-0000-0FEEDDADBEEF;IngestionEndpoint=...;..."
      }
    ]
  }
}
  • Configuration to disable jdbc masking was introduced (#2453): 
    {
  "instrumentation": {
    "jdbc": {
      "masking": {
        "enabled": false
      }
    }
  }
}
  • Sampling overrides can (and should) now be targeted to requests, dependencies, traces (logs) or exceptions (#2456), e.g. 
    {
  "preview": {
    "sampling": {
      "overrides": [
        {
          "telemetryKind": "dependency",
          ...
          "percentage": 0
        }
      ]
    }
  }
}
  • Ingestion response codes 502 and 504 now trigger storing telemetry to disk and retrying (#2438)

  • OpenTelemetry baseline has been updated to Java 1.17.0 (#2453)

Bug Fixes:

  • Fix operation_Id and operation_parentID being captured as 00000000000000000000000000000000 for "standalone" log records (which occur outside of a request). These fields are now empty for "standalone" log records, to reflect that they are not part of an "operation" (i.e. request) (#2432)

Version 0.9.4

  • Support collecting performance counters from 32-bit Windows machines
  • Support manual tracking of dependencies using a new trackDependency method API
  • Ability to tag a telemetry item as synthetic, by adding a SyntheticSource property to the reported item
