All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Unreleased

0.32.0 - 2024-05-15

  • Upgrade opentelemetry and opentelemetry_sdk to v0.23.
  • Upgrade opentelemetry-http to v0.12.
  • Upgrade opentelemetry-semantic-conventions to v0.15.
    • This removes and deprecates some attributes. All removed/deprecated attributes continue to work. Consider migrating to the new attributes in the future. See "Deprecated attributes" in opentelemetry-application-insights documentation for suitable replacements.
  • Set tags Cloud role and Cloud role instance also from resource attributes k8s.{deployment,replicaset,statefulset,job,cronjob,daemonset,pod}.name. This matches the behavior of the JS exporter.
  • Remove option to configure temporality seletor (with_temporality_selector). Application Insights supports delta temporality only as defined in the spec.
  • Add support for ExponentialHistogram export.
  • Add support for span link export.

0.31.0 - 2024-05-09

  • Change how the tags Could role, Cloud role instance, Application version and Internal SDK version are extracted:

    • Spans no longer extract them from span attributes. They still extract them from resource attributes. And they newly extract them also from instrumentation library attributes.
    • Events newly extract them from resource and instrumentation library attributes.

    In addition metrics no longer extract the tag Authenticated user id from the enduser.id attribute.

  • Set tags Device id and Device model based on resource attributes device.id and device.model.name. This matches the behavior of the JS exporter.

0.30.0 - 2024-03-08

0.29.0 - 2023-11-18

  • Upgrade to v0.21.0 of opentelemetry and opentelemetry_sdk.
  • Upgrade to v0.10.0 of opentelemetry-http.
  • Upgrade to v0.13.0 of opentelemetry-semantic-conventions.
  • Improve live metrics performance (#64).

0.28.0 - 2023-10-22

0.27.0 - 2023-08-06

  • Support configuration via connection string (see #54).
    • Configuration via instrumentation key is now deprecated.

0.26.0 - 2023-08-05

  • Upgrade to v0.20.0 of opentelemetry.
  • Upgrade to v0.12.0 of opentelemetry-semantic-conventions.
    • This removes and deprecates some attributes. All removed/deprecated attributes continue to work. Consider migrating to the new attributes in the future. See "Deprecated attributes" in opentelemetry-application-insights documentation for suitable replacements.

0.25.0 - 2023-03-26

  • Upgrade to v0.19.0 of opentelemetry.
  • Upgrade to v0.11.0 of opentelemetry-semantic-conventions.
    • This removes trace::HTTP_HOST and trace::NET_PEER_IP. The keys "http.host" and "net.peer.ip" continue to work with this crate. Consider migrating to "host.request.header.host" and "net.peer.name" (trace::NET_PEER_NAME) / "net.sock.peer.addr" (trace::NET_SOCK_PEER_ADDR).

0.24.0 - 2023-03-11

  • Map level attribute (set by tracing::Level) to Application Insights severity level (see #57).

0.23.0 - 2022-11-12

  • Support sending customEvents (see #53).

0.22.0 - 2022-09-17

  • Upgrade to v0.18.0 of opentelemetry.

0.21.0 - 2022-07-02

  • New feature reqwest-client-vendored-tls, which makes it easy to use reqwest with its native-tls-vendored feature.

0.20.0 - 2022-03-20

  • Use gzip compression (Content-Encoding: gzip) for POST /v2/track HTTP request.

0.19.0 - 2022-01-23

  • Upgrade to v0.17.0 of opentelemetry.

0.18.0 - 2021-09-12

  • Add support for metrics.
  • Take span resource into account for tags. Before a service.name in the resource would not populate the Cloud role name tag. Now it does.

0.17.0 - 2021-08-08

  • Upgrade to v0.16.0 of opentelemetry.

0.16.0 - 2021-06-17

  • Upgrade to v0.15.0 of opentelemetry.

0.15.0 - 2021-05-24

Changed

  • Upgrade to v0.14.0 of opentelemetry. Thanks to @notheotherben.

  • Use HttpClient trait from opentelemetry-http.

0.14.0 - 2021-05-03

Added

  • Add with_service_name function to pipeline builder, which makes it easier to specify a service name (translated to Cloud Role Name in Application Insights). Thanks to @isobelhooper and @johnchildren.

0.13.0 - 2021-03-25

Changed

  • Upgrade to v0.13.0 of opentelemetry.

    The choice of simple/batch span processor as well as the async runtime now needs to be made in Rust code:

    • If you previously used .install() with the reqwest::blocking::Client, you should now use .install_simple().
    • If you previously used .install() with the reqwest::Client and the Tokio runtime, you should now use .install_batch(opentelemetry::runtime::Tokio) as well as enable to opentelemetry/rt-tokio feature.
    • If you previously used .install() with the surf::Client and the async-std runtime, you should now use .install_batch(opentelemetry::runtime::AsyncStd) as well as enable to opentelemetry/rt-async-std feature.

0.12.0 - 2021-03-19

Added

  • New feature flags for using rustls with the reqwest clients instead of nativetls

0.11.0 - 2021-01-22

Changed

  • Upgrade to v0.12.0 of opentelemetry.

0.10.0 - 2020-12-29

Changed

  • Upgrade to v0.11.0 of opentelemetry.

0.9.0 - 2020-12-23

Added

  • Constants for span attribute keys, which you can use to set any of the Application nsights conrext properties (tags).

0.8.0 - 2020-12-08

Added

  • Support for specifying any Application Insights context property (tag) by using span attributes with the internal names of the tags. E.g. the attribute ai.device.oemName sets the client device OEM name context. Thanks to @twitchax for suggesting and implementing this.

0.7.1 - 2020-12-03

Fixed

  • Request and remote dependency durations were off by a factor of 10 (#23). Thanks to @twitchax for finding and fixing the bug.

0.7.0 - 2020-12-02

Added

  • Made ingestion endpoint configurable (#20).

0.6.0 - 2020-11-10

Changed

  • Upgrade to v0.10.0 of opentelemetry.

0.5.0 - 2020-10-18

Added

  • Added PipelineBuilder, a more ergonomic way to configure OpenTelemetry with the Application Insights span exporter.
  • Added support for semantic conventions for exceptions. Events with the name "exception" are now converted into Exception telemetry.

Changed

  • Upgrade to v0.9.0 of opentelemetry. This makes span exports use async/await. In order to support different runtimes, you now need to specify a compatible HTTP client.

0.4.0 - 2020-08-14

Changed

  • Upgrade to v0.8.0 of opentelemetry.

  • Removed .with_application_version function on exporter. Please use the service.version resource attribute instead. See semantic conventions for about the attribute.

    sdk::Provider::builder()
    .with_config(sdk::Config {
        resource: Arc::new(sdk::Resource::new(vec![
            KeyValue::new("service.version", concat!("semver:", env!("CARGO_PKG_VERSION"))),
        ])),
        ..sdk::Config::default()
    })
    .build();

  • Internal SDK Version is now filled from the resource attributes telemetry.sdk.name and telemetry.sdk.version.

0.3.0 - 2020-08-09

Added

  • Automatically truncate any values that are too long for Application Insight.
  • Request Url is now additionally constructed from http.scheme, http.host and http.target if all three are available.
  • Request Source is now filled fromhttp.client_ip or net.peer.ip.
  • Dependency Target now includes the port from net.peer.port and falls back to net.peer.ip if the name is not available.
  • Dependency Type now additionally looks into rpc.system.

Changed

  • Update attribute mapping based on new semantic conventions. The Dependency Target is now filled from db.name (before db.instance) and the Dependency Type is now filled from db.system (before db.type). Thanks @johnchildren.
  • Cloud Role is now filled from the resource attributes service.namespace and service.name (before it was autimatically filled from the current process executable name). This follows the OpenTelemetry specification and gives users of the exporter more flexibility.
  • Cloud Role Instance is now filled from the resource attribute service.instance.id (before it was filled automatically from the machine's hostname). This follows the OpenTelemetry specification and gives users of the exporter more flexibility.

0.2.0 - 2020-08-05

Changed

  • Upgrade to v0.7.0 of opentelemetry.

0.1.2 - 2020-07-25

Added

  • Send span resource attributes as part of request/dependency/trace custom properties. Thanks @tot0.

0.1.1 - 2020-06-23

Added

  • Populate the cloud role tag from the current process name.

Changed

  • Aligned attribute mapping with Azure Monitor exporter for Python and JavaScript. Most notably, INTERNAL spans now create a Dependency.
  • Populate cloud role instance tag from machine hostname instead of using the net.host.name attribute.

Fixed

  • Support events with empty messages. They now get the default message "<no message>".

0.1.0 - 2020-06-21

Added

  • First release.
